Space Marine Adventures: Tyranid Attack!

From BoardGameGeek:

In the 41st Millennium, the galaxy-spanning Imperium wages endless wars against horrors and threats from all sides. Rebellious traitors, jealous alien empires, and the twisted denizens of the warp – an alternate dimension full of nightmarish creatures. Humanity must fight or perish, and for ten thousand years, the elite Space Marines have been the shock troops that offer some respite, taking the fight to the enemy and tearing victory after meagre victory from the clutches of their numberless enemies. Space Marine Adventures is a fast-paced game for one to four players, set in the shadowed corridors of a derelict space hulk infested with ferocious alien Tyranids that have come from another galaxy to consume all life. You must take control of a squad of Space Marines – the Imperium's superhuman warriors – and battle against a host of these alien creatures. Can the genetically modified superhumans survive their perilous mission to find and defeat the dreaded alien leader – the Tyranid Prime?
