Dungeon Defenders is now available for Mac users. The tower defense/action RPG title can be purchased at the Mac store for $14.99. You'll be able to choose between different character classes, build up defenses against relentless enemy assaults, and score epic loot. There are a host of other features which you can see here.
Dungeon Defenders supports four player local or online co-op. Not only is it available on the Mac, it's also available on the PC, XBLA, PSN, and mobile devices. If you have somehow missed out on this great co-op title, pick it up. We gave it a 5/5 in our Co-Op Review.
