Deployment and Forces
Space Marines:
The Space Marine player has one squad consisting of three terminators. One Blood Angel sergeant armed with a power sword and storm bolter, one Blood Angel armed with a storm bolter and power fist and one Space Wolf armed with a storm bolter and power fist. The Space Marine player deploys on the squad on the starting squares shown on the map.
Genestealers:
The Genestealer player begins the mission with two blips, and receives two reinforcement blips per turn. Blips may enter play at any entry area.
Special Rules
Beta Strain Genestealers: This mission marks the first time the Space Marine forces on board the Ark of Dust encounter one of the evolved Genestealer strains. Beta Strain Genestealers have a thicker carapace than the normal "Alpha" Strain Genestealers. As such, even under sustained fire, a Beta Strain Genestealer can only ever be killed by shooting on a roll of a 6. Close combat is unaffected. The Genestealer player has 4 of these special Genestealers to use in the game that can be placed like normal Genestealers whenever a blip is revealed.
Bombs: In order to achieve their mission goals, the Space Marines must place and arm bombs in the rooms marked A, B and C. In order to place and arm a bomb, a Space Marine must be standing in the room and expend a full four action and/or command points.
Victory
Space Marines:
In order to win the mission, the Space Marine player must place bombs in all 3 rooms and have at least one marine leave the board via the marked exit point. If all 3 bombs are placed and armed but no Marines escape the board, the mission can be considered a draw.
Genestealers:
The Genestealer player garners an outright win if he can kill all three Space Marines before they have placed and armed all three bombs. If the Genestealer player can prevent the Marine player from getting a Marine off the board after he has armed all three bombs, he may still attain a drawn result.
