In it, you guide Ratchet and Clank around a tropical island as they chase after a kidnapped girl, bashing plants, robots and other terrors. As in previous games, Ratchet has numerous weapons on hand, including the highly effective Concussion Gun and more. He also turns to Clank from time to time, who wanders into smaller areas and utilizes hovering capabilitie
Sadly, what hurts Size Matters the most is the multiplayer. There are still co-op and versus options, but they're limited to two-player, local split-screen only. There's no online support whatsoever, which is unheard of considering that Up Your Arsenal has it in spades. It's fun for a little while, but hardly something you'll play over the long haul."
