<Dota 2> Dota 2 is the official follow-up to the Warcraft III custom map Defense of the Ancients. It is an "Action RTS" where players control a Hero unit and engage enemy players using their Heroes' unique abilities. Valve is collaborating with one of the primary contributors of the original DotA series.

While Dota 2 was originally developed in the Source engine, it was ported to Source 2 in 2015.
