The Ratchet and Clank series has been going since 2002, and from the first, the little duo has captured the hearts of platform gamers across the galaxy. The series has always primarily been about the insane weapons, and the dynamic duo afterwards.

The latest game in the series, All 4 One, is now available, and adds a new twist to the game: 4-player local and online co-op. Does it work? Does it detract from the fun of the series? Let’s find out.
