Warhammer 40k: Boltgun levels 17-19

Warhammer 40k: Boltgun is a run-and-gun first person shooter set in the grim, dark future where there is only war. You play as a space marine in service to the Inquisition, "investigating" the world of Graia. And by "investigating", we really mean you're violently purging it of heretics and daemons.
Chapter three, woohoo!
