Gearbox has issued an update for Borderlands on PC, which should get you nice and ready for the new DLC once it hits.
If you purchased the game through Steam or D2D, the patch will be applied automatically when you log in, obviously.
The update includes Steam Achievement support, adds 70 Achievements, 42 of which will be unlocked once you load the game. There are 12 you can unlock by fast-traveling to unlocked zones or pulling off an action-skill kill.
Update 1.31 also adds additional support for Logitech’s G-series of keyboards.
There’s no date on the new DLC yet, or an actual name either, but it’s expected before the end of the year.
