Stop me if you've heard this one. Four heroes walk into a dungeon. Together, they set up an intricate series of traps and barriers, all of them cleverly placed so as to dictate a precise flow of traffic, and ultimately designed to slaughter any possible invader. With the floor plan of death put in place, the heroes summon a horde of goblins, wyverns, kobolds and ogres - and go to work.

In short, Dungeon Defenders follows the formula of the ever-growing tower defense genre to the letter. What sets it apart is the fact that it gets damned near everything exactly right.
