Warhammer 40k Warriors of Ultramar

"In the cold darkness of space, the voracious alien Tyranids travel from world to world, consuming all in a futile attempt to slake their hunger for bio-matter. Lying directly in their path is the industrial planet Tarsis Ultra, where Captain Uriel Ventris and the Ultramarines of Fourth Company stand shoulder to shoulder with their battle-brothers from the Mortifactors Chapter. As war rages and the situation looks bleak, Uriel must accept the barbaric traditions of his allies and act against the ancient tactics laid down in the holy Codex Astartes if there is to be any chance of destroying the alien menace. This edition also features the prequel short story Leviathan in which Captain Uriel Ventris and his company are charged with destroying a space hulk."
