A Titan is a general term used by the Imperium for all things that are ridiculously MASSIVE and carry HUGE FUCKING RAPE GUNS that can blow the fuck out off the opposing side. The bigger ones are humanoid Giant Robots. And they say the Tau are the only mecha-using weeaboos in the setting
Most races own a titan of some sort. Each race's Titans reflect the design philosophy behind the rest of their armies. So Imperial Titans are Walking Cathedrals with Gothic architecture with guns poking out of every crevice, Chaos Titans look like a doom metal rock concert made of spikes and evil, Ork Titans are cartoony and cobbled together out of odds and ends also with guns poking out of every crevice, Tyranid Bio-Titans are essentially (even) more toothy and (even) more tentacly forms of kaiju, Eldar Titans are sleek wraithbone slendermen...that incidentally move like him too.
Basically, whoever has more Titans gets instant win... Unless you are in Supreme Commander or Total Annihilation, where their most common units are hilariously larger than your largest titan.
None of the fluff writers seem to have a consistent idea of how big a Titan is (other than that it's big); Graham McNeil says an Imperator is 43 metres tall, Dan Abnett says an Imperator is over 140 metres tall, and the cover of the graphic novel Titan II: Vivaporius shows a smaller Warlord with access ladders on its guns, suggesting that each barrel is the size of a house, which in turn means that the Titan itself would be over half a kilometre tall. Of course none of the writers have read Galileo's essay "Why Giants Don’t Exist". When you double the dimensions of a Titan the weight is increased eightfold, but the load-bearing capacity of the legs only goes up fourfold. . . confused? Well time to do some SCIENCE then!
Take some a dice of all the same size and weight. Arrange into a cube, three dice tall, three dice long, and three dice wide, the cube should have three layers of nine dice. Your cube of dice is now, three times the size of a single die, but notice that it took 27 dice to make that 3x increase in volume over a single die, so it now weights 27 times more than a single dice. This is known as the square cube law since volume is cubic in the radius while surface area is quadratic (i.e. squared), so adding one to how big something is can add a exponential amount of mass. For example, a cube that is 4 meters per side has a volume of 64 cubic meters, while a cube with 5 on each side has a volume of 125 cubic meters.
So if Dan Abnett's Titans obeyed the square cube law they should have very very wide legs(something like the Eiffel Tower), a thin body and head, which exactly the opposite of almost every Titan miniature, with the notable exception of the orks who start off wide and narrow as they go up, makes them almost look like there wearing hoop skirts but offers a low center of gravity making them more stable than their Imperial counter parts. The Adeptus Mechanicus must have some kind of anti-gravity supporting field (not inconceivable), or maybe Games Workshop just doesn't have any engineers on its writing staff (Very much not Inconceivable since an engineer would have better places to be then GW) . Or maybe the awesomeness of the design bends physics, in a universe where they're already shakily applied (also not inconceivable, especially as there is a theory that the Emprah trapped the void dragon on Mars to give themselves control of machinery). Mind you, the above logic only applies when you get close to the maximum load bearing ability of the underlying structures; if a 6 foot robot's legs can hold up double its weight, then the same robot at 12 feet, assuming the square cube law is a problem (see below), is absolutely fine - its legs can now hold up exactly its weight.
The square cube law is not a problem *at all* if the Warhammer universe has arbitrarily strong materials, since we know it has arbitrarily powerful power plants (the problem with the robot's mass is its inertia - you need more force to move more mass, which means more energy); if a Titan simply has legs made of unobtainium, which never break under any yield, and has a plant providing the necessary juice, then the only scaling problems are cost (doubling the size octuples the cost) and mobility (if WH40K had the rules complexity to handle larger objects being easier to hit, Titans would be hit on 2+ by a BS 1 model, and you'd better believe Titans are dense enough to sink in lava, let alone the ocean, and then climbing back out is sticky and complicated).
As of Horus Heresy: Tempest, the Cube-square law is apparently accounted for, the Warlord and presumably any larger titans are equipped with "gravitational and inertial techno-arcana" thereby massively reducing its ground-pressure and allowing a titan to walk safely on smaller moons without pushing off into space. Smaller titans rely on simply being structurally strong enough to take the forces involved Also the cube square law only applies when you're dealing with directly scaling something up, things that are engineered structurally for larger sizes often are heavily reinforced compared to smaller versions, see the difference between a mouse's skeleton and an elephants. same bones and muscle materials, very different internal structures in the bone and much much more muscle for the size.
Imperial Titans
Imagine a city that hates you. Now give it city leveling weapons and legs to walk on, then fill it with more things that hate you. You have a rough idea of a Titan.
The Imperium has quite a variety of titans under the control of Adeptus Titanicus, each has a name and no two are the same.
They are quite often referred to as god-machines due to their ability to blow the fucking shit out of anything in their way. They are so fucking huge that infantry can't do anything to them with their tiny ass guns. These titans can unleash unlimited amounts of RAPE via their MASSIVE FUCKING GUNS that are mounted on their arms and sometimes on their shoulders. Well, actually there are guns fucking EVERYWHERE on a titan, so when you see one you are quite fucked. They also have void shields which makes them pretty much invulnerable to whatever shit you can throw at it. (update: in Epic, infantry can shoot at it enough to overload the Void Shields and bring them down, letting other Warmachines pummel the actual Titan)
Like all machines made by the Adeptus Mechanicus more complex than a toaster, Titans have machine-spirits that reflect their nature. Meaning Titans have machine spirits full of RAGE that want to Rip and tear everything it sees. To combat this, Titans are controlled by individuals called Princeps who possess extremely strong wills which can override the machine-spirit's bloodthirsty nature. However, if the Princeps is not careful in synchronization, then he goes insane and his mind is consumed by the Titan's machine spirit which then goes berserk and destroys fucking everything a la Evangelion.
Imperial Titans are old. As a rule. No exceptions. These things are so old that they make some Eldar Titans look young by comparison. That old. The main reason that these titans are so bloody ancient is that the Imperium often lacks the knowledge, skill, or resources to build them anywhere but Mars, Ryza, and apparently Lucius. The second reason they are so god-dang geriatric is that when Titans get killed, they are usually so big they don't get killed dead. This means that the Mechanicus can haul the thing back to the Titan's home world and fix it up again.
Oh yeah, we forgot. Imperial Titans have home worlds that run the upkeep for a whole Legion of titans of various sizes and classes. A single titan can be deployed by itself, though small detachments of titans are more common, typically the whole legion will "walk" together to end a threat. Because, for the Imperium, if we need to send one titan, we might as well send thirty-plus titans just to be sure that that severe of a threat gets taken care of.
During the Horus Heresy, several of the Titan Legions defected to Horus, giving Chaos its very own supply of Titans. Most of them are relatively similar to their loyalist counterparts, but often they end up getting possessed by daemons, making them far more dangerous.
Imperial Knight: This unique walker is small enough (at "only" 9 meters) to be piloted by a single person, but is no less deadly than a true Titan. They were originally designed during the Age of Strife when several members of the AdMech discovered feudal worlds whose leaders were willing to provide military assistance in exchange for the Mechanicus' technology. Although they have long since been overshadowed by the full-size Titans, the Adeptus Mechanicus still deploys them as a reserve force on occasion.
There are currently nine different Knight variants which have up-to-date rules right now.
- Knight Paladin: Equipped with an oversized Battle Cannon for use in most combat situations.
- Knight Errant: Equipped with a Thermal Cannon to vaporize enemy armor.
- Knight Gallant: A melee knight with a super-cool power fist that can pick up and throw other big dead things.
- Knight Warden: Equipped with a super gatling gun to ventilate mobs.
- Knight Crusader: A dakkalicious knight with both a gatling gun and a thermal cannon or battle cannon.
- Knight Lancer: A Melee Knight Armed with a Lance and Shield.
- Knight Castigator: Armed with a Sword and twin Bolt Cannon.
- Knight Acheron: Armed with a D-strength ChainFIST, and an autocannon-strength Hellstorm template
- Knight Magaera: Lots of anti-infantry goodies, but can swap its standard chainsword out for a D-strength version of a Dreadnought's siege claw, complete with Fleshbane flamer
- Knight Styrix: Murders shit, unique to heresy-era lists, and has the same claw option as its brother, the Magaera
All of them have a reasonable points cost (by Titan standards, anyway) and also wield Strength D chainswords or giant power fists that can pick up and throw whatever they kill if it's big enough. Have fun.
Warhound Scout Titan: The smallest traditional Titan class the Imperium has but it's still fucking massive. It looks like a dinosaur with no tail. It carries smaller weapons such as a massive megabolter which is like a minigun that fires off tank shells, or a Huge ass LAZAR that rips your tanks a new one like they were made of cardboard. Or maybe throw a really big flamethrower on it. Can also be used to scout behind enemy lines and reveal itself behind a bush-CREEEEEEEEEEEEEEED!
Reaver Battle Titan: Bigger than the Warhound so therefore causes more RAPE, this titan can wield an absolutely HUGE powerfist for fucking Wraithlords, Defilers, etc. It can also carry a massive hellfire missile launcher for more rape or triple lehzar rape cannons and even a fucking Gatling Rape Blaster.
Warlord Battle Titan: It's really REALLY fucking big, one of the more common huge fucking titans that carry all the weapons you can imagine from megabolters to huge lazer and devastator cannons that should've been mounted on some kind of fucking battleship. The Imperium seems to have almost as many of these as it has Reavers. Modified or custom built titans are known to exist such as the ANGRY MARINE TITAN with its HUGE chain fist, even moar massive Chain fist, oh and it launches Angry Marines and Land Raiders, fucking awesome rite? Now has an awesome new model.
Imperator Battle Titan: HOLY SHIT IT WEARS CASTLES!!! Over 9000 times bigger and heavier than a Warlord Titan and too many massive fucking guns to count. It needs a whole ship for itself to get around. Unfortunately the Imperium doesn't have a lot of 'em anymore since those chaos assholes stole the majority of 'em (they still suck though). They said that it's the largest thing to walk on land, because anything larger would produce its own gravity well. Oddly enough, it mounts a Ryza-pattern Plasma Annihilator, yet most of these things were supposedly made on Mars. Then again, they might predate differing planetary patterns of weapon. There is a detachment of twelve Emperors that serve one purpose — SCARING THE SHIT OUT OF ANYONE THAT MIGHT THINK OF REBELLION AGAINST THE IMPERIUM. And they FUCKING do. considering the amount of planets and hell, even whole sectors, that regularly defect from the Imperium, their one-hat trick isn't as effective as most people would think.
TL;DR They're what would happen if Cherno Alpha was made by Mormons and grown to twice FIVE times it's size.
GW still has the rules for 40K available on their page Emperor Battle Titan (Doesn't seem to exist anymore.)
Castigator Titan
"By the Fell Gods and the destiny of warp, by the death of the False Emperor and the dying of the stars, we bring to you, Warmaster Abaddon, Beloved of Chaos, Despised of Man, this tribute. For now these last days are the final fires burning, the black flames that consume a galaxy, the storms of the warp that drown out life, the End Times and the dawn of a galaxy of Chaos. We swear fealty to the Gods of Chaos and their herald, Abaddon the Despoiler, with this tribute that it might strike fear into the followers of the Corpse-Emperor and that through it they may see the true face of death..." -The Castigator Titan, on itself
The Castigator-Class Autonomous Bipedal Weapons Platform is an STC Titan believed to be the design all Imperial Titans are derived from (a claim supported by the Titan itself, which referred to all other Imperial Titans derisively as "pale imitations made by ignorant children"), and like everything else made during of the Dark Age of Technology, it is to all other Titans what a Primarch is to a Space Marine by comparison (the Father of all human Titans). It was a towering giant of white and silver, with a faceless head except for its gleaming red eyes. Despite being far larger than any other Titan in existence (standing completely upright instead of hunched over like 40k titans) it proved to be far faster and agile than its bulk would suggest thanks to its unique locomotion system, which featured synthetic muscles supplemented by an automatic repair system. Its weapons were no less advanced, consisting of a Titan Power Fist and a heavily modified rotary cannon of uncertain origin (it fired Daemons). (Some theorize that this was what inspired the Angry Marines to equip their Titans with Angry Marine Launchers and Land Raider Launchers, but nobody has the courage to confirm if this is the case.) Unlike any of the other Titans, it has no crew and is instead operated solely through the action of an artificial intelligence.
- SPOILER -
This turned out to be a very big problem for the Imperium, as the AI in question was advanced enough to fall to Chaos and went so far as to make a pact with the Ruinous Powers, although the book is a bit ambiguous about that too as Justicar Alaric claimed that it was a daemon that had found itself trapped inside the STC during the time the planet it was buried in was lost in the warp, and that it was in there so long it actually started to believe it was the AI. Only the efforts of an expeditionary force of Tech Guard and a single squad of Grey Knights were enough to destroy it, though fragments of its STC database was collected and stored by the Mechanicus shortly afterward to be reviewed at a later time.
Orky Titans
The Orks use titans called Gargants, made out of scrap metal, wood, stolen stuff, and SHEER ORKINESS. They are supposedly effigies of the ork gods, but sometimes they just want a bigger, killier thing than that other ork over there.
Obviously, the Orks have no standard pattern of build, but Gargants are almost always humanoid Orkoid, wield over-sized guns, have a huge close combat weapon, and are insanely hard to take down (even compared to the other races' Titans!). The bigger ones usually move on treads, the smaller ones usually waddle. Either way, these things are slow. But who cares, because they have enough guns to blast the enemy apart, and enough other Gargants to box them in as well!
They have Power Fields, which are so finicky that they can't be repaired in battle, which sucks, but at least they have them.
Ironically, these are the most realistic titans in 40k. Unlike the rest of the titans, these either have massive feet or use treads to deal with the problem of sinking into the ground and are very bottom heavy in order to avoid concentrating the weight on the thinnest part of the structure. If anything, the Orks should have the most impractical titan designs, not the least. Not really though, just the most low-tech sollution
Stompa: The smallest Gargant type. While Games Workshop would like you to think otherwise, the Stompa is bigger than a Mega-Dred but smaller than the current model, which is a small Gargant (don't get all smart and technical, we know the irony there). They come in bunches, and have no shields whatsoever. Their main armament is usually a gatling gun or stolen tank cannon, and then a giant close combat weapon. They eat infantry, buildings, smaller Titans, and tanks for breakfast, but only in close combat.
Gargant: Orky Titans roit an' proppa. They are more in line with the "Stompa" rules GW and Imperial Armor put out. Lots of armor, lots of staying power, lots of dakka(but not enough). Usually has a better close-combat statline than any other Titan counterpart except the 'nids. Due to the lack of pattern, the weaponry varies roughly from stolen Earthshaker cannons to giant gattling guns, plus a gazillion other little guns so the Gargant can fire at everything at once. One configuration has so many guns on it that the entire crew cannot fire them at once. And they somehow generate Supa-rokkits out of thin air.
Great Gargant: The Great Gargant in Space Marine: Epic was what is today simply called a Gargant, and was armed with a mega-kannon, a super lifta-droppa and a ridiculous trouser cannon. The latter fired a giant iron ball which wrecked the hell out of anything short of another Titan and had rules allowing it to roll through multiple targets.
Mega Gargant: Here the line between giant robot and moving fortress blur. Where the Great Gargant is like a skyscraper, this thing actually is a fortress on treads. With a population in excess of a small city, these machines are always moved on huge treads which can literally crush Baneblades beneath them. Slab-sided and covered with gun nests and extra armor patches, this large block-like fortress is home to thousands upon thousands of grot riggers, running to and fro. Powered by salvaged space ship reactors or dangerous Ork-made reactors of questionable physical legality, the engine of destruction has more guns and bigger guns than any other race will mount on a thing of its size. And this is a small mountain. Bristling with turrets, artillery cannons, rocket bays, launch hangers for aerial craft, high-caliber gatling guns, flak turrets, lightning lasers, autocannons, and ONE GIANT MEGA-CANNON, each Mega Gargant is not just as tough as a block of titanium, it can evaporate you through sheer volume of shot. Also, it has the obligatory close combat weapon, which is something easy to move around (like a hammer, axe, or buzzsaw) because it will be so large that the Gargant just may not be able to move it much.
Like the Imperator, the Mega Gargant originated in Titan Legions where it had the dubious honour of having the most complicated rules of any model in the game, requiring the player keep track of dozens of Hit Locations (which could each be destroyed or the subject of a fire that could spread), the Krew (and there were different types of Krew), the Steam Counters, the commander's Shoutin' Counters to actually make the Gargant do anything... and after all that, one was destroyed in a battle report where a Space Marine side with only a basic Warlord Titan won by 105 VPs to 5. This appears to have been about the time White Dwarf decided to switch to narrative, rather than blow-by-blow, battle reports to make bullshitting the results easier.
Other Gargant Variants:
Not all Gargants are created equal:
- Mekboy Gargant:
- Big Meks who build their own Gargants, instead of being contracted by other Warbosses, tend to make better, flashier ones for themselves. They rig experimental weaponry and shielding to the frame, and send it into battle wired up and filled to the brim with bits and gubbins. These mount Power Fields, Lifta-droppa traktor beams (which throw tanks), Zzap gun technology (which is random but eats heavy infantry and light tanks), and all kinds of other crazy junk. Where most Gargants have an arm filled with loads of guns and an arm with a fuckhuge CCW, this one has two gun arms.
- Goff Rokk-an-Rolla:
- Somewhere along the line, the Goffs got the bright idea to Roada Rolla their enemies. This monster eats infantry and tanks, but can't kill other Titans very well. It cuts huge lines in the enemy, and takes no prisoners.
- Goff Klawstompa:
- A pure close combat Gargant, it has two giant claws, and can destroy other Titans in one round of close combat. But other Titans can hit this enemy crab's weak point for massive damage (double meme? Derp), as it has no ranged weaponry. Still, it is very survivable, and can't be stopped by anything once it hits enemy lines. This and the Rokk-an-Rolla are the polar opposite of Mekboy Gargants as they replace the gun arm with another claw or fist or chainblade or even wrecking ball.
- Steam Gargant:
- Sometimes Feral Ork Pigdoks get particularly inspired, and lay about themselves with all the scrap they can find from their raids. They will rope up their whole tribe into building this ridiculously ramshackle machine. This thing could not stand if it weren't for Feral Ork psychosensitivity. The giant machine is always an effigy of Gork or Mork, and features a big close combat weapon (usually an oversized hammer, axe, spear, or mace), catapult and ballista emplacements, maybe a back-mounted trebuchet, rows of platforms for archers, all the trappings of a traditional siege tower, and a GIANT METAL BOILER protruding out of the back. The boiler is fueled by an endless supply of wood, coal, and anything else burnable that a horde of grots can steal off the battlefield. The machine is run by Spannas: random Boyz conscripted to work the machine. May or may not feature a chained Weirdboy or two, who will fire off bolts of lightning from the head or heat the boiler with a stream of arcane energy.
Eldar Titans
Revenant Titan:
Well, yeah back to the Titan: It's the smallest Eldar Titan, and it's also the most useful Titan, as its both fast and agile, unlike some I could mention.
The Eldar field these war machines in pairs - they are piloted by Eldar twins with a strong psychic bond to enable a greater level of awareness and cohesion to the fighting unit. For a race who are dying outand don't breed much you'd think they'd figure out how to just network two titans together or just use the radio rather than building their doctrine around psychic twins but frankly the eldar titans could only be more anime if they were powered by magic and could only be piloted b angsty teenagers.
These agile monsters are considered as scout Titans due to their speed and agility.
It's armed with a Pulsar, which is pretty much made to tackle enemy Titans, like this bitch here. It also has an Eldar Missile Launcher, a rapid firing missile launcher. And FINALLY, it has Sonic Lance, and it's a large flame template infantry killer, which even makes space marines look like pussies.
It also gets Titan Holofields, which works like reverse 4++ against hits (basically forcing your opponent to roll D6 for each hit and completelly negating it on 1-3), which, mind you, stacks with cover saves your titan can get (by, say, hiding behind the building quarter its size, bonus points if it's a 3+ cover fortification), and in case you really want to make it even tougher your farseer may cast a Fortune on it - now you may wish your opponent good luck going through three successive 4+ saves to just touch this thing.
Well, short story, pretty much your basic, Eldar killing machine, and it's the SMALLEST of the Eldar Titans.
Phantom Titan:
The other titan available to the Eldar in IA11. Loaded up with all kinds of fun customizable toys. From the Phantom Pulsar which doubles the standard number of pulsar shots, the Heat Lance which turns titans to molten slag without too much difficulty, the Phantom D-Cannon which throws out an SD 10" pie plate at AP2 and does D3 STRUCTURE POINTS of damage, a power glaive which allows the phantom to take down pretty much any other titan in CC. And it's protected by the same bullshit holofields Revenant does, backed by AV13 and insane amount of hull points.
Warlock Titan:
Old Epic rules included a Psyker version of the Phantom, armed with a big powerfist and a giant Psycannon. It has not been seen since then.
Necron Titans
While no record of Titan-scale war machines exist in Imperial Archives, it should be duly noted that it is well within the reach of Necron technology to create them, and they most likely do exist. The only other race with knowledge on this matter would be the Eldar, who we are sure have already purged the memories of such constructs from their minds PTSD-style.
While many fans speculate over what a Necron Titan would look like, most agree it would be a Necron version of the Iron Giant; i.e. an up-sized, unkillable Necron Lord with guns aplenty.
A machine suspected to be the Necron Titan looked like a worm. (Well, what would you expect from race that most time spends under the surface?) They are called Tomb Stalkers, and are strange beasties that walk and talk like monstrous creatures, but supposedly can take down Warhounds.
There are also the Æonic Orbs and the Tesseract Vaults.
They got advantage that Titans(or similar units) from other races doesn't have: they're more Resistant to Graviton weaponry due to their technology that's advanced enough to ignores Laws of Physics(including Square Cube law among others)
Something that could perhaps be called a "Necron Titan" (or at least the closest they've been seen to have so far. It's more the size of a Wraithknight really) appeared in that old Necromunda comic Kal Jerico: Above & Beyond. It begins with Kal's mother Jena Orechiel basically abducting him from Necromunda's underhive and whisking him away from his life of gun-slinging bounty hunter shenanigans. She took him on a mission to the Space Hulk Kronos which had recently re-emerged from the Warp and where there supposedly rested a powerful alien weapon she wanted destroyed which, after a fun journey through the Space Hulk, turned out to be a giant Necron called The Setekh. Obviously the thing wakes up cranky and starts killing the shit out of Orechiel's retinue as well as the numerous Deathwatch Space Marines some asshole rival Inquisitor named Malva brought with him while taking zero damage from their attempts to fight back (at this point Orechiel comments that defeating it wouldn't be possible even with an entire Space Marine chapter behind them). The only ones to barely escape the hulk alive were Kal, his half-sister and his mother (oh, and her pet Kroot) who commandeered the Deathwatch ship and ordered it to perform Exterminatus on the Space Hulk which was heavily damaged by the ensuing barrage of cyclonic torpedoes and thrown back into the Warp. It's important to note this was before the changes to the Necron fluff so it's likely it never even happened. A shame because fielding this thing in one's Necron army would probably be hilarious.
Another possibility of a Necron Titan happened during the Medusa V campaign where the Necron´s tried to awaken a huge Tomb Spyder like construction called a Crypt Stalker. Unfortunately it got it´s ass handed to it by a bunch of Chaos Titans. However since this is from a time where the Necrons was actually cool and the C´tans wasn´t reduced to overgrown Pokemon, it has likely been shelved alongside the Setekh.
Bio-Titans
The tyranids equivalent of titans are predictably giant versions of other tyranids, following the style of the army in the same way the others do. As in they're giant monstrosities that will either run at you and eat your face off or wield guns that shoot things that do. Obviously, they fall under the Gargantuan Creature rules, rather than any superheavy rules. There are three kinds that currently have models, the relatively small Hierodule, the flying Harridan, and the FUCKHUEG Hierophant. Another exists, in the fluff, a couple more, one called the Dominatrix, which has an Epic-scale model but no rules for it. There's also the even less tangible Hydrophant.
Tau Titans
For much of the Tau's history, they never had Titans or any equivalent to them. This is worth mentioning here because they thought that the idea of any civilization that had the resources and technology to build something like a Titan would surely not be so absurd as to actually waste them in such an impractical manner by building one when creating numerous smaller war machines would be much more efficient. They laughed at the first humans to tell them of Titans, assuming that it was only Imperial propaganda to intimidate their enemies. Then the Damocles Crusade made them turn their blue skin several shades paler as they realized that the gue'la were crazy enough to actually build them.
They suffered horribly at the hands of Imperial titans, but for some time they still considered titans too impractical to be worth building. Even so, they needed some ways to counter them. Mantas were in the same mass class as titans, and had big enough railguns to threaten them, and while almost invulnerable to most titan class weapons (since they aren't designed against flying targets, even ones big enough to be mistaken for real estate) it were too vulnerable to massed anti-tank weaponry (like lascannons) in turn, and a bit too valuable to lose cavalierly. So they ended up manufacturing a version of the Tiger Shark bomber equipped with Manta-scale railguns. For a time, it seemed to work at forcing the Imperium to be more careful about deploying titans against the Tau, since a single flight of bombers can rip up a formation of titans and replacements for those bombers can be (relatively) easy to manufacture compared to the titans it threatens. Funnily enough this is what actually happened in the real world, only replace "titan" with "battleship" and you have a perfect example for the dominance of modern naval combat, although with the introduction of anti-ship ballistic missiles such as the DF-21d and the high cost and maintenance is really stretching the relevancy and practicality of ships such as Aircraft Carriers.
However, due to the increasing number of Imperial Knights and Tyranid gargantuan creatures the Tau have been facing during their expansions, it has become clear that the tried and true method of spamming bombers and Mantas is no longer sufficient enough to properly take on these new threats (with the mantas being too valuable to risk mutual destruction with Knights equipped with dedicated anti-aircraft weaponry, and the bombers not being quick enough for rapid deployment against newly arriving war machines and also being vulnerable to anti-aircraft weaponry). In order to have a chance against these opponents, the Tau needed something that could go toe-to-toe with these towering monstrosities, or at least bombard them from long range while still being tough enough to withstand being a massive bullet magnet itself.
In a move that would have previously seemed foolhardy and wasteful to try, the Tau just said "Fuck it!" and decided to take a page from Pacific Rim, building their own Titan in order to fight everyone else's. The result was the KX-139 Ta'Unar Supremacy Armour, the first Titan-class battlesuit of its kind. While it still can't fight in melee very well, it does have two TL burst cannons and smart missile systems it can fire Overwatch with (at BS2, no less) to discourage enemy assault forces. For its arm weapons, it can equip either a Heavy 5 multimelta for popping vehicles or an ion cannon that can fire either 6 shots at S7 AP3 or 3 shots at S9 AP2, both of which are superb for massacring heavy infantry. The back-mounted Pulse Ordnance Multi-Driver can fire either a Strength D Massive Blast with 72" range or a S8 AP3 Apocalyptic Barrage with Pinning and Ignores Cover with a range of 12-120". Defensively, it has a 2+/5++ save that improves to 4++ against shooting attacks, and it can sacrifice the invulnerable save for a turn to cut the number of wounds suffered from a "Deathblow" result on the Destroyer table in half, allowing it to withstand as much damage as it can dish out, especially since it's a Gargantuan Creature with 10 wounds.
Fielding Titans
Unfortunately fielding a titan in a tabletop game will cause lots of RAGE and presents itself as a huge fire-magnet, so every fucking thing on the other side will try to shoot at it. Luckily it's got shields, so it can soak up a lot of damage. Should said titan 'get killed' it may take out the whole field (if its a small one), and all those units around it, enhancing its awesomeness. Too bad that, since you are forced to buy one from Forge World, everyone who sees you with one will call you a rich noob who buys his way to victory. (Anything larger than a Reaver has to be built from scratch. NOT ANY MORE!! For the price of a mere £1240 you can now buy a warlord titan model from Forge World, sure it's a rip-off but who cares. It's an awesome model. If you want to make an accurately scaled miniature of an Imperator, it's actually easier to stand on the table while wearing a sign saying "Imperator Titan"- it's that big.) AND, you have to play Apocalypse (or Escalation)[1] which SUCKS Lord of Wars permitted in normal games from 7th edition. But who cares? YOU HAVE A GIANT RAPE MACHINE OF DEATH!!!!! (If you really want to field a Titan and you are smart enough to realise that apocalypse sucks, you could always organize a game where it's 1 Titan vs an equal points number of normal stuff. Would be a weird, probably unbalanced but fluffy and fun game. Or just a titan showdown, possibly 1v1.)
EMERGENCY WARNING
Lukas the Trickster WAS able to troll them so hard that their owners and their dogs would rage quit instantly but, thanks to the 7th edition codex, he can't do that crazy shit anymore! His "The Last Laugh" special rule used to remove any model in base contact with him when he died, including titans, but now functions only in a challenge, thanksfully, meaning he can only threatens characters. His reign of terror is finished. (at least for Titans)
