Defense of the Ancients 2

Defence of the Ancients, or DotA as it is more commonly known, began life as a custom scenario for Warcraft III: Reign of Chaos. An anonymous developer known as IceFrog has been custodian of the mod ever since, making regular updates.

Valve has confirmed that IceFrog will be working with them on the sequel.

DotA 2 will launch on Mac and PC in 2011.
