Missed out on the definitive Borderlands 2 experience in the Steam Sumer Sale? Don't worry, you can still pick up the Borderlands 2 GOTY Edition for just over a fiver at the Mac Game Store, and because it's a Steamworks title the code will also work on PC.
So what do you get? Most of the major DLC packs released so far, which includes Tiny Tina's Assault on Dragon Keep, both Ultimate Vault Hunter Upgrade Packs, the Mechromancer and Psycho characters, Creature Slaughterdome, Collector's Edition Pack, Premiere Club, and a number of character customisation skins and heads.
