'Ratchet and Clank: All 4 One' Brings 4-Player Co-Op

Leapin' Lombaxes!  Insomniac wasn't all about the Chimera during their presentation in Germany -- the company also brought us our first look at the next installment of the beloved Ratchet and Clank series in Ratchet and Clank: All 4 One.

Now that Ratchet and Clank Future storyline is complete, Ratchet and Clank: All 4 One brings us back to our Lombax roots, continuing the original storyline of our favorite wrench-throwing hero and his lunchbox/backpack.

In this story, Dr. Nefarious's latest bungle traps him inside his own machines along with Ratchet, Clank, and Captain Qwark, forcing the evil robot to work along side the heroes to escape.

All 4 One will let gamers play as any of the four characters in drop-in/drop-out, online, four-player, co-operative play (say that three times fast.)  Undoubtedly, the players will have to work together to solve the platformer's puzzles and fight their way through the game -- similar, I'm guessing to the time puzzles from Crack in Time.

Ratchet and Clank: All 4 One is slated for release in 2011.  Here's hoping it's sooner rather than later!  For now, we'll just have to satiate ourselves with this trailer:
