Trendy Entertainment have been showing off Dungeon Defenders, their upcoming tower defense-esque game, at GDC. Our friends over at GameTrailers have put up a video showing off some gameplay with one of the developers explaining some of the different systems. The game seems to be in a similar vein to the Blitz mode found in Monday Night Combat, with players all defending using their different abilities. The video also boasts the ability to play with others on different platforms. Specifically it mentions the players working together on an iPad, Android device, PC and PS3 all together. Although XBLA isn’t mentioned in the video, the game is still slated to be coming to the platform at some time in the future.
