A great addition to the Ratchet & Clank series.
Having miny missions as Ratchet in jail was a nice touch to the game. Most of the other people in jail we're put in by Ratchet so it probably won't be a hospitable visit. Your basically fighting guys you put in jail from the other games ( which is cool ). Clank can buy weapons for you, some from other games and some that are new. It's just fun to still have the Ratchet playing in this game.
Quark is now wrighting an auto-biography about his "heroic deeds". This is the first time you really get to play as Quark and it is actually pretty fun. So you play through his stories and a thing that I thought was cool is that if Quark starts to talk and changes the story it happens while you're playing, like from ninjas to big buff ninjas. You will probably find parts with Quark that will make you laugh.
This is overall a great game. Fom encountering old enemies to fighting evil cactus's with Quark. If you like Ratchet & Clank you'll love this game.
