Those who have played the first Borderlands will get exclusive access to character heads and skins in Borderlands 2. The unlocks will be available once the game has detected the save games of its predecessor. Unfortunately there is little information on the unlocks with only a single image detailing what players will get. But it lacks any information showing how much of the first game will need to be completed. The only clue is that the exclusive contest will be available for what the poster calls Vault Veterans but how many of the side quests will need to be completed (if any) remains a mystery.
