I got my copy of All 4 One two days ago and I started to play the offline single player experience.
My thoughts on this game so far is like a love hate relationship. There are some elements that I really love about the game such as the audio/music, cinematic sequences, concept idea and variety in the gameplay. Although, the controls and pesky glitches is something you really got to get used to, especially those glitches.
It's not as amazing as the older games and the future saga, but it's something to check out if you're into multiplayer co-op and Ratchet and Clank. I'll give you guys my full thoughts after beating the game.
