you can also follow the walls depending on the angle the room is.Well I stopped using mhs now....100 fcr @ mf runs makes everything easier.
Another point is, that the map (chambers lvl 2) before meph is ALWAYS the same. The wp is just always somewhere else and the "stairs" to the next or previous lvl. So if u find one "stairs" u know where the other one is
Thx @ all who posted here.
