Please note that the DCS: M-2000C, and all future DCS World DLC releases on Steam, will now use Steam Keys instead of Starforce keys. As such, these purchases cannot be activated on the DCS World e-Shop version. Previous purchases will not be affected.
Well this sucks for some people and I hope they make a disclaimer on all Steam purchases so no one misses this. Probably should be a separate post somewhere here from DCS official in case someone misses the email or post.
