The authors of the long-in-development Classic Offensive mod for Counter-Strike: Global Offensive have shared a message to Twitter that it has been rejected from release on Steam and its app retired after eight years of development.
I have sent a request for comment from Valve and will update this story if I hear back, but the rejection may be due to Source engine workarounds used by the team when creating the mod.
