Changes

The [[Dark Angels]] had repelled a [[Genestealer]] incursion in the Tolevi system many centuries ago. A Dark Angel hero was leading his men aboard the invading [[space hulk]], [[Sin of Damnation]], when it vanished into [[Warp|the Warp]]. The player's , a [[Deathwing]] [[Termimator]] and his squad is sent to investigate the Tolevi system for a distress call of the Dark Angels' origin. Genestealers have infested the planet Ma'Caellia, and the player's forces are ordered to destroy the aliens' [[Hive Mind]]. However, there are too many Genestealers, and the Marines are forced to withdraw. Without any other options, the Marines performed an [[Exterminatus]] on the planet with using [[Virus bomb|virus bombs]]. As they are doing so, the Sin of Damnation re-enters the system, and the player receives orders to invade the hulk. Aboard the vessel, the player's squads destroy the Genestealers' gene banks and their [[Genestealer Patriarch|Patriarch]]. The end of the campaign tasks the player to control a lone Marine as he goes deep into the hulk to find the source of the distress call.
