Counter-Strike Online is a first-person shooter video game, targeted towards Asia's gaming market released in 2008. It is based on Counter-Strike and was developed by Nexon Co. Ltd. with oversight from license-holder Valve Corporation. It uses a micropayment model that is managed by a custom version of Steam.[1]


The game features a variety of additions over the international Counter-Strike, such as the introduction of female characters, numerous new weapons and skins for previous weapons. Most of the weapons are "locked" by default, so virtual cash or in-game points are essential to purchase them. Most special weapons, skins, power-ups, etc. can be purchased with cash points. A variety of other special items can also be bought with in-game points as well.

Counter-Strike Online itself is free to play, but some weapons are bought using points purchased with real money. These weapons usually expire after a certain amount of time but sometimes can be purchased permanently during a promotion. Certain weapons and items can be purchased with points that are gained by getting kills, completing objectives, etc.


Counter-Strike Online includes classic Counter-Strike modes and added more. They are categorized as six: Classic, Deathmatches, Zombie Infection, Scenarios, Fun and Others.

  • Classic: Round-based match. The modes available are Bomb Defuse, Hostage Rescue, Assassination and Basic.

  • Fun: Spin-off modes that are fun to play. Modes available are Hidden, Bazooka Battle, Soccer, Challenge and Item Battle.

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.[2] It has been confirmed that Counter-Strike Online 2 uses the same Source version as Counter-Strike: Source.
