Yes, internally the battletech code stores things as x,y,z coordinates and
during presentation time maps these coordinates onto a hex map.  As far as
the user is concerned, they're working with a hex system.  Some unit types
can jump or fly and the terrain is not flat, so the various distance and
collision routines take altitude into account as well.  However, that's
the extend of the 3d-ness to the game.. its basically 2d at heart, just
like the table top game the online version is based upon.

Its been a very long time since I worked with the code, but I can probably
still answer questions about it if there's any interest in the details
under the hood.

Later,
Brad
