Based on Valve’s Counter-Strike engine Nexon developed a free-to-play online version which is released in Asia only. The long-running MOFPS enjoys still huge popularity, nurtured by Nexon's constant content updates and events. Throughout the years Counter-Strike Online has grown massively in content. In addition to the classic Counter-Strike game modes, Nexon added scenario, fun, survival and PvE zombie modes and many in-game characters. Especially the zombie modes are popular among the 25 game modes which are for example available in the Korean version.
