Reverb Publishing and Trendy Entertainment are showing off Dungeon Defenders this week at GDC. The series debuted earlier this year with Dungeon Defenders: First Wave, the only iOS title (besides Infinity Blade) to use Epic Games’ Unreal Engine 3 and the only Unreal-based Android game. Second Wave will soon come to Sony’s Xperia Play as a two month exclusive, and will arrive for the Xbox Live Arcade and PlayStation Network later this year.
