At some point in the future, Borderlands 2 will be getting another playable character as downloadable content. We don't know what this escaped experiment is called, or what it looks like, exactly, but this teaser trailer from developer Gearbox gives me some ideas.
PAX East attendees who want to find out more information will want to make room in their schedules for the Inside Gearbox Software panel on March 24 from 12:30pm to 1:30pm.
