"About an hour ago we received a tip that a couple Gearbox employees had tweeted about Borderlands coming to Steam. While many people assumed it would be inevitable, I hit up Gearbox to see if I could get official confirmation, and official confirmation I got.
Not only will Borderlands be releasing for download on Steam, Steve Gibson of Gearbox also told us about a couple additional features that will be exclusive to the PC version. Given the amount of unique weapons in the game, you'll probably end up with some sweet-looking gun that none of your friends have. Want to show it off? You'll be able to export item cards to .jpg files. Additionally, the PC version will come with timedemo benchmark software, which admittedly isn't needed for the console versions, but will be a nice touch."
