The Lab (by release date)Dota 2 is the official follow-up to the 
Warcraft III: The Frozen Throne custom mod Defense of the Ancients (DotA, retroactively called Dota 1, originally released in 2003). Developed and published by Valve alongside IceFrog, the original developer of the first game, 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 and ran in 
Source engine in 2013, using the Dota 2 engine branch which formerly succeeded CS:GO engine branch, it was later ported to 
Source 2 in 2015 as part of Dota 2 Reborn update. This also makes Dota 2 the first Source 2 game (though the first game to be completely made in Source 2, and not ported from previous engine was Artifact, or The Lab - Robot Repair).
