Unfortunately all of this running and gunning comes at a small price. The game will occasionally slow down when the shooting gets fast and furious and too many of the game's achievements appear to be broken, with players needing to start up their own characters to get some of them well after the achievement's requirements were met in co-op. Busted achievements certainly aren't a reason to not play the game, however it's a shame for folks to not get the points they have coming to them.

Even with these problems, the desire to keep leveling up, to keep getting stronger, to keep getting better weapons, better shields and better stuff is strong enough to overcome them. Packed with so much stuff to see and kill, Borderlands offers plenty of things to aim your spiffy new weapons at, all the while providing one of the best co-op experiences of the year.
