To celebrate the launch of Dungeon Defenders on XBLA, Trendy Entertainment have released this brand new trailer for your enjoyment. Released for XBLA yesterday, Dungeon Defenders is a 4-player co-operative Tower Defense, Action-RPG. We’ve already fallen in love with this one and in our review we described it as one of the largest, most polished XBLA titles to date. Wow. You can pick up Dungeon Defenders from Xbox Marketplace for 1200 MSP.
