On April 5, 2012, Nexon and Valve announced a partnership to develop
Counter-Strike Online 2, which is based on an enhanced Source engine and offered enhanced graphics, powerful impact physics, and more new features. It ran a closed beta test on 16 November 2011 and an open beta test in June 2013. After a period of open beta testing, it was released in December 2013 in the Asian markets, but it was closed on April 26, 2018. Maps in this game are taken from
Counter-Strike: Source. Some are heavily modified in terms of graphics, such as
Dust II, Inferno, and Italy. The game also adds its own exclusive maps. The weapons are taken from
Counter-Strike: Source as well as adding new weapons. The weapon models are heavily modified and reanimated. They are separated into pistols, shotguns, submachine guns, assault rifles, sniper rifles and machine guns. Some weapons can be obtained for free while others can be obtained for points and achievements. Some weapons need the player to collect the given kill points to unlock them. ==Spin-off==
