Borderlands

Lock, load, and face the madness!
Get ready for the mind-blowing insanity, as one of four trigger-happy mercenaries, taking out everything that stands in your way.
RPS (role playing shooter) combines frantic first-person shooting action with accessible role-playing character progression.
Co-op frenzy: fly solo in single player, wreak havoc with a friend in 2 player split screen, or drop in and out with up to 4 player co-op online and offline for a maniacal multiplayer experience.
Bazillions of guns: gun lust fulfilled with rocket-launching shotguns, enemy-torching revolvers, smgs that fire lighting rounds, and tons more.
