Yup, fail... noclip right outside of "The Vaults" (Yes, I admit, it's a lame easter egg...)

It is also possible to hovel glitch outside of the map... the alien base, and the Dropship Zone. Transit, though, has the best hovel glitch that I know about in any of the default maps, it's even better, because humans can get out too, xD..

Anyways, I'm very curious about the "semi-elaborate puzzle" in citadel, though.
