First upload - essential. This is the original vanilla quake-c with all the compiler warnings fixed. You could base a mod on this, however I would recommend Painkeep 2.2 update or hipnotic for all the extras they contain.
Painkeep 2.2 update available here - Moddb.com
I could not find the hipnotic .qc files anywhere - guess I'll package those, upload them next and throw in a link.
