I have them all with the exception of Quest for booty, even going back to all the PS2 games, this one is by far the worst. Its a different idea in the "tower defense" but the storyline is weak, the game is also extremely short(took me some 3 hours to beat start to finish), definitely not worth the $20 to buy, barely worth the rent for it. Very disappointed even though I knew what I was in for to an extent from reading other reviews. Ebay will be the next stop for this game.
For a platformer series that has had great weapons, funny characters, and silly plots. A great storyline from start to end, Level after level of fun, These last few ratchet and clank games are obnoxious. 1 game that your not allowed to solo through, playing the same missions over and over forced to deal with other players is annoying, and an even greater let down is this atrocity, turning a great game potential, into a tower defence game... Ratchet and Clank have lost the love I once had for their games.
