About the Game
Play as Malum Caedo, a fearless Space Marine, on his perilous mission to locate a shard from a mysterious power source on Graia, a Forge World on the brink of being overrun by Cultists, Traitors and Chaos Daemons. Scour the place, acquire devastating weapons and holy equipment, and PURGE THE HERETICS in this retro shooter!
Become the ultimate warrior of the Imperium, wielding your deadly arsenal to explore the violent and iconic Warhammer 40,000 universe. Dominate the battlefield with the awesome firepower and heavy metal of a Space Marine’s devastating weapons, as you battle against the Chaos Space Marines and Daemons.
Take control of the mighty Malum Caedo– along with his faithful servo-skull – and plunge headlong into your mission on Graia. Retrieve the Power Source fragment on the Forge World and cleanse the archenemy from its surface! Roam through bastions, cathedrals, corrupted canyons, hellish furnaces and war-torn environments.
Dive into a visceral combat experience, complete with viciously satisfying gunplay, high mobility and buckets of blood to reward your skills. Rely on your indomitable chainsword to eviscerate your enemies. Dash, jump and slice the foulest heretics across the galaxy! Unlock new deadly weapons like the Shotgun, Meltagun or Heavy Bolter and equip yourself with different types of devastating grenades. Show no mercy!
Experience a perfect blend of Warhammer 40,000, classic, frenetic FPS gameplay and the stylish visuals of your favourite 90’s titles. In glorious boomer shooter style, unleash your devastating weapons as you blast through an explosion of sprites, pixels and blood. Discover an exceptional aesthetic, with retro cutscenes and pixel art backdrops, paying tribute to a historic era in video games.
Want to take purging to the next level? Annihilate endless swarms of enemies in the new horde mode, available for free. Blast each and every heretic standing in your way, trample on their remains and cleanse their foul heresy. For only in death, does duty end.
