Co-op tower defense action-RPG (phew) Dungeon Defenders is celebrating its first year of existence with some party favors and a sale. For the next two weeks, the "Dungeon Defenders Anniversary Pack DLC" is free. It finds our pint-sized heroes wearing party hats and defending a newly decorated tavern homebase from wave after wave of monsters trying to destroy the birthday cake crystal core.
Dungeon Defenders is also 75 percent off as part of Steam's midweek madness sale, making the core game a mere $3.74. Want to be a big spender and receive all of Dungeon Defenders' content? Well, better cancel that trip to The Olive Garden tonight, because that's going to cost $12.49.
