Insomniac Games has kicked off the limited Beta for Ratchet & Clank: All 4 One, giving lucky PS3 players the chance to test out two sections of this co-operative adventure with lots of weapons and character’s special ability.

According to a post on the PlayStation Blog, “the first scenario is the opening level of Luminopolis where Ratchet, Clank, Captain Qwark and the evil Dr. Nefarious are forced to band together when Nefarious’s light-eating Z’Grute is unleashed upon the city.”

“The second area of the beta jumps you deeper into the action with The Vertigus Cliffs, set in the N.E.S.T. area of the treacherous Planet Magnus is a unique area full of vertical views that look stunning in 3D. The Vertigus Cliff level will also give you a chance to check out some mechanics from later in the game, including use of your weapon wheel and many of the crazy Ratchet & Clank weapons you’ve come to know and love.”

Unfortunately you’ll only be able to jump into the beta if you have a special code, but keep an eye on the developer’s Twitter and Facebook pages for chances to win extra codes. And get ready for the demo for the game that will arrive in October, before the full game launches exclusively on the PS3 on the 18th of October.
