Die-hard Ratchet & Clank purists might want to watch out for this "black sheep" title in the catalog. The closest comparison to this game is Ratchet: Deadlocked for the PS2. This game focuses more on co-op gameplay than it does on exploration and the RPG elements of the prior games. All 4 One features a locked camera and up to 4-player online or offline cooperative gameplay (although 2-player co-op is most ideal). Although a lot of fans of the original Ratchet & Clank formula will be turned off, this is still a pretty good title to check out as long as you keep an open-mind.Pros+ lots of fun if you have some buddies to play through with+ great-looking cut scenes with witty dialogue and great voice-acting+ varied weaponry and upgrades+ many varied locations+ still contains skill points, trophies, and the RYNOCons-locked camera-lacks exploration of previous games-Weapons and health aren't upgraded through frequency of use anymore-some irritating glitches and bugs (dieing during the final boss fight for no apparent reason)
