Warhammer 40000 Boltgun 2 continues the retro-style first-person shooting of its predecessor, set in the grimdark Warhammer 40,000 universe. Players control a Space Marine battling hordes of heretics and daemons with a powerful arsenal of weapons.

The game builds on the original's fast, old-school shooter design, delivering more relentless combat within its pixelated, franchise-inspired sci-fi setting.
