===Crotalids===
Originally written by [[Graham McNeill]] at some point when he was involved in rules design. Crotalids are amphibious reptiles that look like somewhat like skinny Crocodiles and have a unique biological ability to migrate through the warp. They show up on a planet, screw with its ecosystem due to the introduction of an apex predator, then move to another planet once all the prey have died off.

Unlike the Devils, they are fully intended to be played as a neutral faction, as most of the time the players have no control over when they show up or what they do.

'''Special Rules'''
*'''Territorial''' - Crotalids are an unplayable faction in the game and do not behave as other models on the table do.  Instead, during '''each players movement phases''' the Crotalid pack will move 6" towards the nearest non-Crotalid unit. If they reach base-to-base contact with this unit they will have counted as charged that unit in the following assault phase.
*'''Animal Nitrate''' - At the beginning of '''each players assault phase''', any unengaged Crotalid unit must make an assault move of 12" towards a non-Crotalid unit. If no units are in range then the Crotalids take no action.
*'''Fight or Flight''' - Crotalids are affected by morale as normal units of their type, however if the pack is ever caused to fail a morale check from any source, then they immediately migrate away from the battlefield and are removed from play.  Yet, despite being animals, destroying a pack of Crotalids (whether through killing them all or making them flee) ''does'' count as a kill point to players in missions which award them.
