Borderlands 2 50% off on Steam; play for free this weekend
Steam's weekend deal is for Borderlands 2. If you don't own the game by now, here's yet another chance, as it's 50% off -- dropping the price from $19.99 to $9.99. That's just the basic Borderlands 2 game, though. If you want all of the DLC and characters and extra quests, you can buy the Game of the Year version for $19.99, discounted from $39.99.
No matter what it is, even if you just want some of the DLC, it will be 50% off.
But wait, that's not all! You can play the full game for free this weekend until Sunday. Go... get to it!
