The Ratchet & Clank series is known for big-ass guns and the Lombaxes who love them. Insomniac's platformer series has sold millions of copies and spawned numerous sequels, and a new one, Ratchet & Clank Future: A Crack in Time, is coming at the end of October. Series creative director Brian Allgeier provided some insight into how the team comes up with Ratchet's ridiculous weaponry (and provided an exclusive first glimpse at some newly unveiled guns) last week at PAX. We taped it in its entirety. My favorite part is when he unveils the Groovitron montage.
