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 the Steam back-end.
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.
