Key points

Organner Server Fans discovered an unofficial server using Radmin VPN.

Counter-Strike Online 2 (abbreviated as CSO2 or CSOL2) was a multiplayer first-person shooter game developed by Nexon, who licensed the Counter-Strike intellectual property from Valve. The sequel to Counter-Strike Online, Counter-Strike Online 2 ran on a modern version of the Source engine similar to that which Valve had used for Counter-Strike: Global Offensive. The game was online-only, requiring players to connect to a master server operated by the publisher of the game in their region in order to play the game. CSO2 operated using a free-to-play model, with various items being purchasable with real-world money via a microtransaction system.

CSO2 was announced on April 6, 2012 as a successor to Counter-Strike: Online, though the latter game would continue to be supported. Recruitment of playtesters for CSO2 began on July 16, 2012, with closed beta testing commencing on August 2. On August 6, 2013, the beta was opened to the public, and on November 28, CSO2 officially launched in South Korea.[1]

On February 22, 2018, Nexon announced that they would be discontinuing support for Counter-Strike Online 2.[2] When Nexon's master server shut down on April 26, 2018, it became impossible to legitimately play the game, as players could no longer proceed past the login screen to enter the game itself. Modders have since developed alternative launchers for CSO2 that allow players to connect to custom, privately-hosted servers still running the game, though many of its features, such as character customization, remain inaccessible.
