: Added Golden Chests and SHiFT code support to the original game for the first time, providing a new way to obtain legendary gear.
: Anyone who owned the base Borderlands 1 game or the original Game of the Year Edition on Steam was automatically entitled to the Enhanced version.
: You did not need to own any of the original DLC to get the Enhanced edition; the new version included all four expansions— The Zombie Island of Doctor Ned , Mad Moxxi's Underdome Riot , The Secret Armory of General Knoxx , and Claptrap's New Robot Revolution —for free.
: A new mini-map (similar to the one in Borderlands 2 ) replaced the original compass, making navigation and tracking objectives significantly easier.
