Editing Warhammer 40,000/Xenos in 30k (section)

==== Building a Genestealer Infestation Army ====
* A Genestealer Infestation Army is chosen from Codex Tyranids.
* A Genestealer Infestation Army may only be used when playing a Zone Mortalis game. A Genestealer Infestation Army will therefore use a standard Zone Mortalis Detachment and will not use any special Tyranid Detachments or optional detachments, except by agreement.
* A Genestealer Infestation Army may only select Genestealer units (Broodlord Prime, Genestealers, Alpha Genestealers, Ymgarl Genestealers, Buster Genestealers).
* The opposing force gains a free Spearhead Sentry Gun (see the Isstvan III Zone Mortalis Stratagems from ''Horus Heresy Book One Betrayal'') for every 1,000 points in your force, or part thereof. This is true even if that optional special rule is not being used in the mission.
* '''“They mostly come out at night… mostly.”''' —  Genestealer Broods may choose the following options:
** Genestealer Broods may upgrade every model to have the Hit and Run special rule for 6pts/model.
** Genestealer Broods may upgrade every model to have the Move Through Cover special rule for 3pts/model.
** Genestealer Broods may upgrade every model to have the Stealth (Zone Mortalis) special rule for 3pts/model.
** Genestealer Broods may pay an additional 50pts, and, when the unit has been destroyed, an identical unit may placed into Ongoing Reserves.
*'''“What do you mean, ‘''They cut the power''’?”''' — The Genestealer Infestation player can always elect to use the Night Fighting rules.
*'''“Nuke the site from orbit. It’s the only way to be sure.”''' — The Genestealer Infestation player’s opponent may always elect to use the Attrition optional special rule in Zone Mortalis games.
*'''“That can’t be; that’s ''inside'' the room.”''' — The Genestealer Infestation player can always elect to use the Enemy Unknown optional special rule in Zone Mortalis games. Additionally, Genestealer Units can move through locked doors if they pass an Initiative test (this does not open the door, it simply allows them to move through it, representing the use of a duct or similar means to bypass it altogether).
*'''“They’re coming outta the goddamn walls!”''' — If, when a Genestealer unit nominates a unit that will charge, the distance in inches of all models in the Genestealer unit to any model from the unit that they’re charging, is equal to or greater than the double the highest Initiative score of the target unit, then the Genestealers may take an Initiative test (a roll of 6 always fails). If this test is passed, they gain the Jink special rule for the Assault phase.
*'''“What the hell are we supposed to use, man?”''' — If the Cold Void & Poisoned Air optional special rule is in effect, any ranged weapon with the Melta, Shred, or Rending special rule but without the Template range or Pistol type, plus any Missile type weapons, gain the Gets Hot! special rule, and non-Genestealer units gain no benefit from Assault or Defensive Grenades, to represent the Genestealers making deliberate use of volatile and precarious accessways to discourage ranged attack with high-powered weaponry.
*'''“They’re all around us, man!”''' — If more than one Genestealer unit charges into the same combat on the same Charge sub-phase, all Genestealer units in that combat count as having Assault Grenades.
*'''“Maybe they don’t show up on infra-red at all.”''' — Units gain no benefit from the Night Vision special rule when targeting Genestealer units, and Genestealer units gain Feel No Pain (4+) against any weapon with the Ignores Cover special rule, unless they have the Template range.
*'''“Game over, man! Game over!”''' — Genestealer units cause Fear.
