"Co-op is king in One 4 All. You can wander through the wacky wondrous worlds presented before you alone if needs be, but that would completely defeat the purpose of this project. It’s about getting around with your friends (3 to be exact) and it’s quite competently executed. You can play as any Ratchet, Clank, Quark or Nefarious, each one with their own skill-set and abilities to layer and vary the co-operative experience. Collectively, you’ll solve puzzles, manipulate the environment, navigate moving vehicles, traverse exposed gaps in the scenery and take out any number of huge alien monsters. It’s core R&C gameplay multiplied by four. That’s not a bad thing."
