Light on story and heavy on guns. Borderlands 2 is saved from XP strip-mining by a sharp sense of humour and a slick, destructive multiplayer.
Lots and lots and lots of guns; Utterly compelling; can't-stop-yourself loot collecting; Great world; backed by some razor-sharp wit; Co-op is laser-focused and smart
Story never feels like it's driving the game; Easy to get ground down by the grind
