DotA is a free mod based off of WarCraft III. Guess this means it's gonna be some kind of third person sky camera game, like Alien Swarm(Valve's free sky camera game).

The Elements of War camera system, available in ALL Source/Gold Source games/mods is perfect for a sky camera game. Unlike Zelda/Nox/Diablo/Alien Swarm and any of the others, my system allows the player to always look to the north of the screen. When you turn left or right, the screen rotates clockwise or counter-clockwise with you. Making it the perfect upgrade to any FPS'er player looking to play a sky camera game.
