Guardians of Middle Earth Trailer

In time for next week's E3, below is a trailer for Guardians of Middle Earth, a "Defense of the Ancients" (DOTA) style game. DOTA refers to the Warcraft III free mod that pits at least two teams against each other under the command of a "hero" unit with the goal of destroying the opponents' Ancient building while simultaneously defending their own. The Hero unit leveled up by destroying enemy fodder units and enemy heroes (which resurrect after a time delay). I guess in this case the idea will be to have Hero (Gandalf, Gollum, etc.) representing each faction as they probably protect various environments of Middle Earth. I assume actual game play elements will be demoed at E3.
