Step into the chaos of Darkenstein 3D, a bullet-dodging retro FPS set deep behind enemy lines.Inspired by the brutal pace of Return to Castle Wolfenstein and the glory days of late 90s shooters, this game blends secrets, explosive physics, and a story driven by desperation… and a dog. You play as the Hobo Guy: a furious American drifter lost in enemy territory, armed with nothing but a shotgun and pure vengeance. It’s 1940s Germany, and though you’re outnumbered and outgunned, you won’t back down. This isn’t about justice, it’s personal! Gunther, your loyal companion, was taken during a Nazi raid. Now he’s locked away deep inside enemy fortresses. To get him back, you’ll need to push your limits through an uphill battle against the Axis forces. Along the way, you’ll uncover alien secrets, strange powers, and hidden horrors in a world crumbling under war. Fast, brutal, skill-based. Darkenstein 3D doesn’t hold your hand. Enemy projectiles can be dodged, but survival requires sharp movement, precise aim, and quick thinking. Every battle is a deadly dance of strafes and corners. No cover mechanics, no aim assist, just raw gunplay. Take on 13 handcrafted levels that steadily raise the stakes. Explore castles, caves, valleys, and desert towns. Unlock doors with hidden keys, discover secrets, hunt for treasure, and push your score higher and higher. You won’t fight alone. A vicious rat companion joins the bloodbath, lunging at enemies and sowing chaos in close quarters. Combine him with grenades and mines for maximum destruction. He’s small, angry, and always hungry. Explosive gore, ragdoll physics, and debris-filled firefights: every shot feels heavy, and every kill looks painful. Enemies fly, gib, and collapse in glorious carnage as the battlefield crumbles around you.

No microtransactions. No battle passes. No currencies. Just one complete, standalone retro FPS the way it used to be. Built over four years by a single developer, Darkenstein 3D is a passion project turned full campaign. It’s hard, it’s funny, it’s handcrafted, and it’s packed with hours of replayable carnage.
