Valve confirmed that the leaked source code was indeed legitimate and that includes code from a 2017 build of CS:GO. It even contained Team Fortres 2 code from a build of the game back in 2011. Needless to say, fans of the two popular Valve titles expressed their discontent over the leak, saying that it could lead to widespread cheating and malware development by unscrupulous developers. According to YouTube personality Tyler McVicker, he says that the code was allegedly leaked by a group of developers who had unauthorised access to the code since 2018. McVicker has apparently tried to stem the leak of the source code but was caught unprepared when one member of the group decidedly released the code. In act of vengeance for being removed from, of all things, a Discord group.
— CS:GO (@CSGO) April 22, 2020 As for concerns of cheating and damage to the gameplay on both CS:GO and Team Fortress 2, Valve has been trying to soothe the frantic wave of gamers. Assuring them that they have no reason “to be alarmed or avoid the current builds” and recommended that the games be played on official servers, and not fan servers.
