Is there a predetermined number of secret roons? ie 1 obvious 1 not so obvious amd 1 super secret?
Also can they only appear in the GC or cam there be secret rooms in the UT?
Yes, as of now, all special rooms are predetermined and always exist in each game, only their location is randomized.
I'd be all for having chance-based generation of special rooms, because that would allow for hundreds of hand-made rooms with special contents, only a handful chosen for each game. Much more variety, much more fun.
