This game is intense. It can be as long and as short as you would like it to be. I know most people don't like UMS games, but this one is worth a shot. You get a hero, run around and kill other players/NPC's until your army is strong enough to destroy their base.

A really intense game, and if you haven't already done so, get the map and head on over to battle.net and check it out.
