Terminator Armour
Chaos Space Marines in Terminator armour are capable of moving and firing with heavy weapons thanks to the bulky exo-skeleton and powerful servos built into the armour. They are as a result slightly cumbersome and may not be able to pursue lighter opponents so may only consolidate when victorious in close combat and may never sweeping advance. Any model in Terminator armour has a 2+ Armour save, a 5+ Invulnerable save and adds +1 to its Attack characteristic. Terminators may teleport onto the battlefield and set up using the Deep Strike mission special rule if the mission allows these rules to be used.
Errata — Chapter Approved: Codex: Chaos Space Marines Q&A (v3.0): This entry should also state that models in Terminator armour count as stationary when shooting, even if they moved that turn — letting them fire heavy weapons without penalty.
