Sting: The Secret Operations

Sting: The Secret Operations was a free to play game by YNK Korea. An open beta began in December 2008 (https://www.gamesindustry.biz/sting-source-engined-online-fps-currently-in-open-beta). It appears that the game was launched in multiple markets and was known as Sting Online or Sting in Korea, Code Name Sting in Japan and K.O.S: Secret Operations in the Philippines and United States.

In March 2013 it was announced that the game would be shutting down (https://www.facebook.com/photo/?fbid=10151464108668518&set=a.452443728517).
