A co-op dungeon crawl with hack-and-slash action for up to four players and a surprising amount of scale and complexity. There are many stages to brawl and shoot your way through using a mixture of attacks and combos, an extended leveling system for becoming more powerful, and tons of hidden and not-so-hidden items with varying effects. There are a number of playable characters with unique looks and animations, though movesets are basically the same and characters mostly differ by stat allocation.
