Conclusion: Moon Diver tries its hardest to be exciting, and at times, its entertaining. If you're going to play by yourself, be prepared to grind your way through, attempting each level a number of times to improve your character's stats. The only way to experience the whole game with relative ease is by dipping your toes in the online pool.
Summary: A four player co-op hack-and-slash, Moon Diver boasts frantic action and unique co-op twists. Sadly, a series of baffling design choices make it impenetrable to both solo and multiple players. Moon Diver is simply a mess that's unlikely to please all but the most devoted fans of the genre.
