I see that in the rikti crash site map (not to be confused with the current rikti war zone map) that the creys folly gate is open. But I have yet to find the old creys folly map with the gate to the crash site open. Does it exist still or was it completely overwritten and replaced?
You'd have to use a version of the map prior to Issue 10. Everything since then would've been closed off. Check the disc releases (http://paragonwiki.com/wiki/Disc_Releases) article on PW to see what game boxes you could find that would have it.
