Now that work on Resistance 3 is complete, Insomniac Games can turn its attention to its other baby, the Ratchet & Clank franchise. Often lauded as one of the best platforming series ever made, and among the best PS3 exclusive titles, Ratchet & Clank return later this year with a new game, Ratchet & Clank: All For One.

But if you can’t wait until the game is released on October 18, then you are in luck. And terribly impatient. For the first 25 people that post a comment below, we will send you a key that will give you access to the closed beta demo of the game. Insomniac’s Senior Community Manager, James Stevenson explained what to expect with the demo via 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. New Weapons like the Frost Cannon, Plasma Bomb Launcher and Warmonger give you a great assortment of guns to play with, but old favorites like the Combuster are back as well. There are LOTS of weapons in the beta, as well as character’s special ability.

Right now the demo is only accessible by invitation. Those that were at the Insomniac Community Day, or who won a contest may already have their codes, but for everyone else here’s your chance to win.

Just tell us what you like about the Ratchet & Clank series, and the first 25 responders will be emailed codes. First come, first serve. Good luck to all, and look for Ratchet & Clank: All For One as a PS3 exclusive in stores on October 18.

These keys are only useable in North America.
