Surprise hit Dungeon Defenders has sold a million units across Xbox Live, PSN and Steam, the game's publisher told us in a recent interview. The well-received co-op tower defense action game launched on October 19, 2011, and has kept a steady sales beat going on Steam with deep discounts and consistent support.
"It is tremendously successful franchise," Reverb Publishing CEO Doug Kennedy said. "We have lots of plans to support it both with DLC and additional add-ons for the franchise."
