Like the original Borderlands, there are four playable classes in Borderlands 2. Developer Gearbox has been forthcoming with the Gunzerker and Siren classes - bringing them out at various trade shows and preview events - but have kept quiet on the other two characters: Zero, the katana-wielding assassin and the new soldier, Axton.

After spending a sizable chunk of time with the other two characters, I wonder why they were ever hidden away in the first place. Zero and Axton in Borderlands 2 are responsible for some of the most stylish and exciting combat options I've seen in the game.
