Borderlands 2

[tigerparrow]

Borderlands 2 is a hybrid First-Person Shooter, RPG game focused on over-the-top co-op play, and set in the open-world game environment of the planet Pandora. The second game in the game series, Borderlands 2 raises the 'loot and shoot' action of the original game with an even larger and more detailed world to explore, an updated gun system, a new cast of characters and character classes, and integration of storyline with action.

I absolutely loved the first one - there was a storyline, albeit one that didn't get in the way of shooting stuff.
