This game is amazing i love how u can level up your weapons and buy more, plus its very fun. the robots also seem kinda human. But the only problem in this game is that there aren't enough checkpoints during hard missions and this can get frustrating. These 3-d naughty dog games such as Daxter (also amazing,) and ratchet and clank , and agent clank really bring out the best of the psp's power while keeping the game fun. This game provides extras such as Captain Qwaurk missions Ratchet mission which also let you use the weapons available in Ratchet And Clank size Matters. This game gives the chance for Clank to buy weapons for ratchet and these include: The Shot Rocket, The Plasma Whip, and many more weapons and mods. The game could be improved by allowing further leveling up on some weapons as it adds more personal goals in the game. The Bottom line : This is an awesome, fun game
