Switching between any of your five on-screen team members: Robin, Beast Boy, Cyborg, Starfire and Raven could be fun, if you could find them more than half the time - they're constantly hidden behind scenery, enemies, or special effects - and if there was ever any real reason to do so. They all share a health meter, control the same, and their AI tends to make them more interested in the scenery than in helping you pound baddies. At least the intelligence deficit works both ways: even the bosses are content to follow a simple alternation between attacking and waiting for retaliation.
Thirty-six different characters (Vixen, Mammoth, Jinx) can be unlocked over the course of the single-player story mode. But you can only play as those new characters in the versus - er, excuse us, "Master of Games" - mode. And though the arenas are stocked with falling debris, arcing electricity and patches of slow-down goop, there's just not enough meat on these bones to make even a single satisfying multiplayer meal. The co-op mode, by contrast, genuinely amps up the fun factor.
