Well this is a surprise: Gearbox has released the Mechromancer DLC for Borderlands 2 a week early. It was originally scheduled to go live across Xbox 360, PS3, and PC on October 16, but it appears that Gearbox has finished it up a little ahead of schedule. If you pre-ordered Borderlands 2, the Mechromancer DLC is a free bonus as part of your membership in the Premiere Club, whereas everyone else with have to pay $10.
The Mechromancer is Borderlands 2's fifth playable class, and is essentially the game's pet class. The Mechromancer's action skill allows her to summon a robot affectionately named "Death Trap," and a number of her skills center around making Death Trap better. If you're planning on starting a Mechromancer the next time you boot up Borderlands 2, you can plan out your character to level 50 with the skill trees found on the Borderlands 2 official site.
Before you download the Mechromancer DLC or the patch that accompanies this release, however, you should know that some users are reporting issues with the downloads. Apparently, that nasty bug which wipes badass ranks is rearing its ugly head again, and users on the both the Gearbox and Giant Bomb forums are thinking that the DLC and patch downloads may be a trigger for the issue. The bug has also been wiping out unlocked skins, heads, and even entire character saves.
Gearbox has yet to make a statement on the issue, but still, tread carefully. It may be a better idea to wait on the Mechromancer download until we get official word from Gearbox, just to be on the safe side. We'll have more information for you once we hear something from Gearbox, so keep it tuned right here to SlashGear for more information.
