We've been pretty interested in the development of One what with its fun-sounding cooperative mechanics and huge boss battles. And, I mean, c'mon, it's a cooperative Ratchet and Clank game! We've previously heard few details on the story of the game, however. For those of you wondeirng just HOW Ratchet, Clank, Qwark, and Dr. Nefarious end up in a situation where they must band together, the following story trailer may clear up some of your lingering questions. It also shows off some of the cooperative swinging and shooting that we've heard about in the past.
