The Playstation Blog announced today that Ratchet & Clank: All 4 One has been given a release date.

The game will arrive in stores October 18th.

A step away from its single-player only predecessors, the game will feature a cooperative multiplayer where you can take control of Ratchet, Clank, Captain Qwark or Doctor Nefarious as they all work together to get back home after they find themselves trapped in a machine called the Creature Collector.

Also announced today were pre-order bonuses.  Players who pre-order the title through Amazon.com will get a T-Rex Morph Weapon Mod to transform enemies into baby T-Rexs.  If you pre-order the game at Best Buy, you will receive a Kerchu-engineered flamethrower.  Reserving the title at GameStop will net you the Mr. Zurkon robot that flies around and fires laser blast at foes.  Finally, pre-ordering the game through Wal-Mart will unlock the classic Sheepinator Morph Weapon Mod that transforms enemies into sheep.
