Dungeon Defenders features a lovingly-rendered watercolor art style and allows up to 4 players, online or locally, to take one of four distinct classes into fierce battle against ever-increasing waves of baddies and bosses across 15 arenas and multiple modes.

Tower defense fans and RPG nuts alike will find themselves enthralled by the depth of the character progression. Each class has a slew of towers and skills in their arsenal with 90 levels worth of stat building with all four DLC packs.  All this makes for a chaotic, fun romp of a time in expertly crafted dungeons full of monsters attacking from every angle.

Dungeon Defenders is now available free on Xbox Live online entertainment network from Microsoft starting today, March 16, through Monday, March 31, as part of the Games with Gold program for Xbox 360.
