Despite what the back of the box for Ratchet & Clank Future: A Crack In Time might have said, Insomniac Games newest PlayStation 3 exclusive will not feature a multiplayer component.
As cautioned earlier, that PS3 box art for the new Ratchet & Clank was based on a standard template and "not final," according to Insomniac. So don't expect to see a well hidden surprise multiplayer component in the final game, nor any of the other features listed in error.
"As we've said before, [Ratchet & Clank Future: A Crack In Time] is a single-player game, and has been planned as such from the very beginning," reads a statement. "We're totally focused on wrapping up the Ratchet & Clank Future story arc that we started in Tools of Destruction, and continued with Quest for Booty."
