This is a modification for the real time strategy game Warhammer 40k : Dawn of War. The mod is based on the very popular Spacehulk Table Top game, and to some extent also the computer game, which is also called Spacehulk. You control a squad of 5 Space Marine Terminators of the chapter’s first company. The squad is the Chapters Elite, specially trained to operate in the most dangerous of battlefield conditions and in the dark vacuum of starship boarding actions.
If you aim for the classic boardgame (or simply don’t have dawn of war) try this very good remake
