Ratchet and Clank: All For One has been unveiled by Sony.
The game is being developed by Insomniac's North Carolina office, with studio director Chad Dezen demonstrating the game during Sony's Gamescom press conference.
The title allows gamers to control Ratchet, Clank, Quark and Nefarious seperately, and players must work together and against each other to complete tasks.
Users can drop-in and drop-out of play at any time.
The announcement was made shortly before Insomniac revealed its blockbuster FPS sequel, Resistance 3.
