The Dota 2 engine branch (Pre-Reborn) was introduced in 2013 with the release of Dota 2. It used to be the latest Source branch available, succeeding the Counter-Strike: Global Offensive engine branch, however with the release of Dota 2 Reborn update im 2015, the game was upgraded to the then-new Source 2 engine, which makes CS:GO the latest Source 1 branch available. Additionally, this is the only Source 1 engine branch that was never licensed to third-party developers.
