Hey, remember the girlfriend mode character, the Mechromancer? Maybe you got too caught up in the PR fiasco there to remember, but yes, Borderlands 2 has another class coming out on October 16th. That's still a ways away, but you can start fiddling with the classes' skills now!
Just head on down to the Borderlands 2 website, which has an interactive skill tree where you can configure the build of your dreams. It also gives you a closer look as to what Gearbox originally meant when they made the girlfriend remark.
Those with the Season Pass will be able to get the class free of charge. For others, she'll be paid DLC. I for one am glad she exists, because she'll be useful for newbies and, hey, it's another woman character! That's always a plus.
