Counter-Strike Online is a remake of Counter-Strike: Condition Zero targeted towards Asia's gaming market. It is being developed by Nexon Corporation of South Korea with oversight from license-holder Valve Corporation. It uses a micropayment model that is managed by a custom version of the Steam back-end
It's made by Nexon, instant suck.
CS:O is only for Asia, and it's just CS:CZ. CS:S uses source and therefor it's superior.
