Contour interval in TOC

[76mm]

Elevation intervals are easy to change if you don't like them, although obviously changing them could impact the realism of the game as designed; as Strela mentions, if the only issue is the movement cost of changing contours you can also change that value in the pdt file.

If you open a PzC map file in a text editor, the third line is a bunch of numbers which represent the successive elevation contours in the game--you can change them in the text file to change the elevations. Obviously, save a copy of your original map file.
