[Korean source] According to an article from South Korea, Smilegate has revealed that CrossFire 2 is currently in development. The project started just this summer, and currently is looking to fill the team up with development staff. Smilegate is also working on several games, including the Marvel MOBA.
CrossFire has been the top online shooter in China for many years, while its effort in Korea previously fell short. With significant earnings from the China market, Smilegate will be re-launching CrossFire in Korea again later this month. The English server is currently still very active.
