Blake Stone 1: Aliens of Gold

Before Blake Stone: Aliens of Gold, the world only knew of one man who could mow down Nazis in a maze of corridors — then Blake showed up with a laser gun and a mission to rid the universe of alien gold hoarders. Released in 1993 for DOS, this game is like Wolfenstein 3D’s sci-fi cousin who read too many pulp comics. The enemies range from mutants to scientists who clearly never took an ethics class. The voice acting is... charmingly robotic, and the gameplay is fast, frantic, and unapologetically pixelated. Expect secrets behind every wall and an endless supply of keys to doors you didn’t ask for.
