Attack the Genestealers and their more frightening cousins, the Tyranids, in their huge living ships. Your job is to take a squad of Space Marines into the bowels of the ship and try to destroy it's vital organs. The ship is not defenseless as you could find a Genestealer or the larger more dangerous Tyranids opposing you. This time, lighter armored but faster marines in addition to the heavily armoured Terminaters are going in, but unlike the opponents in the game Space Hulk the opponents now have weapons.
