Borderlands 2on Steam this weekend, and it's been drastically reduced in price if the game's brand of wacky co-op violence is your cup of tea.
The free weekend ends at 1pm PDT, but the game remains at 75% off until Monday August 25. Every bit of Borderlands 2 DLC is also on sale, including all mission packs and skins.
Basically it's a Borderlands 2 free-for-all. You can grab the Game of the Year Edition, which packs all the extra content up, for $9.99. It's part of a larger , which includes games like XCOM, Bioshock Infinite and Civilization 5.
If after all that you STILL crave more shooting and looting, you can pre-order Borderlands: The Pre-Sequel for 10% off. It's out on October 17 this year.
