The single-player campaign stars you as a Librarian Terminator, more interested in powerful Psyker abilities than overdue books, and you and two of your Space Marine buddies are journeying deep into a derelict vessel – a Space Hulk, in fact – while taking down Tyranids and slowly gaining progression via a light RPG system. It's not just the Genestealers you'll fight, as you also put rounds into cast of other enemies, but you're mostly here for the main event.

After this, they'll try to ambush you in just about every way they can, crawling down walls towards you or clawing their way out of vents. It expands the gameplay environment, beyond the narrow maze-like corridors of the original board game and earlier video games, to include massive space ship. You'll see a Genestealer before you fight one, see them skittering over pipes before a set-piece pits you against dozens of them all at once. Space Hulk itself was a board game that itself took inspiration from Aliens, remixing the setting to let players play out the story of probably-doomed Terminator Space Marines trying to survive against ravenous Tyranid Genestealers, but with this live game, they double down on the inspiration. The last-stand defences and desperate attempts to survive against all odds are reminiscent of tense moments in those games, but the biggest debt Space Hulk: Deathwing owes is to Aliens. Space Hulk: Deathwing owes a debt in part to both Left 4 Dead and Warhammer: Vermintide.
