I think Treyarch knows that you want Radiant. Don't post spamtopics about it.
I bet they'll release it after all the map packs
ADD ME ON STEAM: AKNINJA612
(Still implying protecting a .ff with a flag for it being a DLC map which can be removed and replaced in \usermaps\ is a safe way to prevent piracy...)
But *locked*.
Only post bugs you experience with the Mod Tools and other features you want other than Radiant.
