Recently I got a lot of PMs asking if CrossFire will be closed down soon, now that CF2 will soon be released. This post will tell you all you need to know regarding this matter:
First off, CF2 is separated from CF, it's not a content update like the 2.0 patch - so, if you play CF2, you will start over from the beginning without your stuff from CF. There are no words regarding account transfer option, and even if there is, I don't think CF2 will have all weapons available in CF so you can transfer between them.
Second, according to this thread, Tencent already managed to extend licenses for CrossFire, meaning they will be able to keep this game running for at least another 3 years. With that being said, CrossFire will NOT be closed down in the near future and it will run alongside CF2.
So, rest assured, we can still enjoy this old game for a while - I know CF is quite outdated and its graphics are not the best, but hey, if it ain't broke don't fix it.
