Warhammer 40,000: Space Marine

Step into the ceramite boots of Captain Titus, a battle-hardened Space Marine of the Ultramarines chapter. Warhammer 40,000: Space Marine throws you into a brutal third-person action adventure on an Imperial Forge World—a planet-sized factory churning out the war machines humanity needs to survive. A millions-strong Ork horde has overrun the facility, and losing it is not an option. As you fight through the green tide, a far more sinister threat lurks in the shadows, waiting to reveal itself. This Anniversary Edition, updated to version v1.0.165, delivers the complete campaign with all the bone-crushing combat the title is known for.

Gameplay and Story

You control Captain Titus, a veteran of countless battles, as he leads a small Ultramarines force to reclaim a vital Forge World from an Ork Waaagh! The game emphasizes aggressive combat—there is no cover system. Instead, you charge headlong into enemies, using melee finishers to regain health and build momentum. The weapon roster includes iconic Warhammer 40k armaments: the bolter, the plasma gun, the melta gun, and the chainsword. Each weapon has distinct handling, and you can carry two at a time, swapping on the fly.

As you progress, you earn experience points that unlock new weapons and upgrades. The Anniversary Edition bundles all DLC, including the Exterminatus co-op mode and additional multiplayer maps (though multiplayer servers may not be active). The campaign takes you through varied environments, from the surface of the Forge World to its dark underbelly, and introduces the Chaos threat that lurks behind the Ork invasion. The story is delivered through in-engine cutscenes and radio chatter, with strong voice acting that captures the grimdark tone of the Warhammer 40k universe.
