This Free ‘Wolfenstein’ Inspired Shooter Lets You Fight Nazis With a Pet Rat

Remember When Shooters Were Simple?

There was a golden age of gaming. An era before online stores, before daily logins, and before every game needed a ten-year roadmap. It was the age of DOOM and Wolfenstein 3D, where all you needed was a powerful weapon, lightning-fast reflexes, and a legion of bad guys to blow into pixelated gibs. A new game, Darkenstein 3D, has just crash-landed on Steam, and it’s a glorious, blood-soaked love letter to that very era. And the best part? It’s completely free.

Developed by a single passionate creator and published by the legendary MicroProse, Darkenstein 3D isn’t just inspired by the classics-it feels like a lost relic from the 90s, lovingly restored with modern physics and a whole lot of chaos. This is a game that respects your time and your skill, offering pure, unadulterated, old-school action without asking for a dime.

A Quest for Vengeance, Fueled by Spite (and a Dog)

The story is exactly as brilliantly unhinged as it should be. You play as the “Hobo Guy,” a furious drifter who finds himself trapped behind enemy lines in 1940s Germany. The Nazis have made a fatal error: they’ve kidnapped your dog, Gunther. Your mission is simple, brutal, and deeply personal: get your dog back. What follows is a rampage through 13 handcrafted levels, from dark castles to secret bunkers, as you tear through waves of Axis soldiers.

But this isn’t just a historical shooter. As you progress, you’ll uncover a bizarre conspiracy involving aliens and zombies. The game gleefully mixes genres, keeping you on your toes as you face down everything from soldiers to extraterrestrial threats. And you’re not entirely alone. You have an unlikely ally: a vicious pet rat that you can unleash to attack enemies and cause general mayhem in every firefight.

Pure, Unfiltered Gameplay

Darkenstein 3D proudly wears its inspirations on its sleeve. The gameplay is fast, unforgiving, and skill-based. There’s no regenerating health, no cover system, and no hand-holding. Your survival depends on your ability to move, shoot, and dodge. It’s a true “boomer shooter” at its core.

Here’s what you can expect when you dive in:

  • Fast-Paced Action: Movement is king. You’ll be circle-strafing and bunny-hopping your way through hordes of enemies, just like in the good old days.
  • Physics-Driven Carnage: Enemies ragdoll, explode, and turn into satisfying piles of gibs. The combat feels crunchy and impactful.
  • A Quirky Arsenal: You’ll have access to classic weapons like shotguns and a flamethrower, but you can also throw your rat at enemies. You can even eat pie and drink beer to regain health.
  • Secrets Galore: Every one of the 13 levels is packed with hidden areas, traps, and treasures, encouraging exploration and rewarding curious players.
  • Zero Microtransactions: The developer has been very clear. This is the full game, for free, forever. There are no battle passes, no cosmetic shops, and no hidden fees. It’s just the game.
