Warhammer 40k: Leviathan

The Imperium fights for its very existence against a threat unlike any other in the galaxy, and a Tyranid invasion beyond any yet experienced. The fortress world of Regium has a proud history, standing defiant in defence of the Imperium of Man for millennia. But now it is shaken. Parasitic plagues run rampant, and Regium's citizens face a dire threat. Rallying his warriors, the battle-hardened veteran launches a strike force to slaughter the xenos in the outer system before it can reach Regium. But as this new tendril of Hive Fleet Leviathan proves unpredictable and deadly, Castamon and the First Company must harness all their skill, might, and zeal, or face utter annihilation.
