Mutant Chronicles
Mutant Chronicles is sci-fantasy setting created by Target Games in 1993. It is best described as Shadowrun IN SPAAACE, although it is set only in Solar System. Also, it borrows some inspiration from W40K. It has megacorporations, cyberware, cyberspace, hueg guns, swords (heck, even chainswords!), shoulderpads, mutants (duh), religious fanatics, demons, magic... And it is pretty grimdark too.
Originally it was only RPG, than came card game (Doomtrooper), wargame (Warzone, similar to Warhammer) and several desktop games. There is even 2008 movie adaptation directed by Simon Hunter, but completely derped… basically they just used the name of the franchise and several characters. But hey, it has Ron Perlman, John Malkovich, Thomas Jane and Sean Pertwee, which is quite awesome if you ask me.
Human factions:
Capitol: megacorp based on USA. Media masters, strong airforce. Their homeland is Mars.
Bauhaus: megacorp based on Germany, Italy, France and Russia. Best quality products, strong tanks. Their homeland is Venus.
Imperial: megacorp based on British Empire. Very aggressive and expansionist. They have no homeland, but have enclaves across whole inner Solar System, mainly in Asteroid Belt.
Mishima: megacorp based on Japan and other Asian countries. Basically, weaboo in space. Katanas, power armors, mechas, Ki powers… yey! Their products are cheap and shitty quality. Their homeland is Mercury.
Cybertronic: newest megacorp, most technologically advanced. Full of robots, cyborgs, matrix. Their HQ lies on Luna, but they have stations on other planets too.
Brotherhood: religious sect, Catholic rip-off. And they have Inquisition! It is based on the teachings of the First Cardinal, who was like Emperor – helped humanity to rise from age of technological apocalypse and kick some heretical ass. Now, Brotherhood has banned AI… but Cybertronic don’t give a single shit about this. Their de facto homeland is Luna.
Cartel: inter-corporation "peace organization", like UN in real life. It's purpose is also to fight the Dark Legion. Armed forces consists of Doomtroopers, super-elite warriors equipped with best weapons and wargear.
Dark Legion:
Dark Legion is infernal army from beyond, awakened on 10th planet Nero (Pluto was still considered as planet back then). It has five demonic leaders, Dark Apostles, and consists of undead creatures, mutants, demons, aliens from different planes, heretics and killing machines.
Algeroth: like Khorne
Ilian: mistress of seduction (like Slaanesh) and magic (like Tzeentch)
Semai: made of just as planned, exactly like Tzeentch
Demnogonis: just like Nurgle, but not obese
Muawijhe: just like Malal… basically Freddy Krueger with army of nightmares or Joker with god-like powers. Take your pick.
