I made a very small 3 player map with all of our snow tiles and most of our rock tiles.

My wife and I played the first game on it with the following armies:

Wife:
Sudema 140
Sentinels of Jandar 110
Nakita Agents 120
Nilfheim 185
555

Me:
Jotun 225
Gladiatrons x 2 160
Blastatrons 60
Major X17 100
545

A liberal starting position policy allowed the Sentinels of Jandar to grab the Thorian and Defense glyphs on the first turn. Major X17 moved up to prevent the 3rd one from grabbing the attack glyph and to prevent Nilfheim from taking the two hexes of highest ground in the middle of the map. Not only did Major X17 do that but he actually killed a Sentinel with three skulls to one shield.

Gladiatrons started marching in to take the attack glyph and try an assault on the Sentinels. They got the glyph but attacking Sentinels with six defense dice didn't go anywhere. Nilfheim...
