Borderlands 2 is getting its second downloadable character, Krieg the Psycho, starting tomorrow. We gave a run-down of his skill trees in our hands-on, but just in case you'd rather hear it from Sir Hammerlock, a new trailer scratches that itch.

The launch trailer details Krieg's skills: Mania, Hellborn, and Bloodlust. The trailer shows off the different skills in action and suggests a few key skills that help define each tree, so you can start planning which path sounds best for your particular psychotic murderer.
