Even in it's current incomplete state of Early Access, Prodeus is one of the finest examples of the genre, standing tall amidst the retro FPS revival games a la Ion Maiden, Dusk, and mods like Brutal Doom. The movement is brisk and responsive, the weapons are tactile and purposeful, the levels are complex and varied without feeling like a labyrinth of back-tracking time waste. Top to bottom this game is a blast and worth every penny.
