There was a fun mod "no fences" for S.T.A.L.K.E.R. Shadow of Chernobyl, that allowed the player to leave the "natural" gameplay areas by removing fences around them and allowing to explore the half-implemented climatic terrain that was only visible remotely from "the inside".
Is there some counterpart - a mod, a patch, a cheat, a console command or something like that, that works in S.T.A.L.K.E.R. - Call of Pripyat? I realize there's less outside the gameplay area for Zaton and Yanov, but a significant part of Pripyat is cut off and I'd love to explore it.
