Dungeon Defenders has expanded its perspective on PC and Mac gameplay (and probably life and love and stuff) with the new Summoner character, who can conduct battle from on high as if in an RTS. Overlord Mode allows the Summoner to supervise entire armies from a top-down perspective, altering the game entirely.
Along with omniscient battle control, the Summoner gets two pets, can levitate for 15 seconds, build an army from sentient crystal and basically wreak havoc on the battlefield, as the above video shows. The Summoner DLC pack is available via Steam for $4.
