Built as both a tribute and an evolution of classics like Wolfenstein 3D, Doom, and Return to Castle Wolfenstein, Darkenstein 3D is fierce, funny, and ferocious — everything fans of retro shooters crave. Inspired by the glory days of late 90s shooters, this game blends secrets, explosive physics, and a story driven by desperation… and a dog.

Step into the boots of the Hobo Guy, an American drifter caught deep in enemy territory during the 1940s. When his loyal dog Gunther is kidnapped, vengeance becomes the only mission. With nothing but a shotgun, grit, and a rat companion hungry for blood, you’ll battle through bunkers, castles, valleys, and deserts to get him back — uncovering alien secrets and bizarre powers along the way.

Step into the chaos of Darkenstein 3D, a bullet-dodging retro FPS set deep behind enemy lines.

MicroProse and solo developer Rowye announced that Darkenstein 3D: Total Trampage will launch for PC (Steam) on October 14, 2026 and requires the base game. The complete original Darkenstein 3D campaign remains free to play.
