Counter-Strike: Global Offensive started off as an Xbox 360 port of Counter-Strike: Source by Hidden Path Entertainment. Seeing this as an opportunity to expand the franchise, Valve turned it into an entirely new game. The game uses the latest version of the Source engine and is not built off of Counter-Strike: Source. After the success of the previous game, Valve wanted the newest game in the franchise to cater to both the casual and competitive community by including a matchmaking system as well as support for dedicated servers. Valve announced the beta would begin in October, but after receiving feedback from professional players who had been invited to playtest earlier versions of the beta, Valve decided to delay the beta. After addressing the majority of the issues the closed beta started on November 30, 2011.
