The game is set in a science fiction future where the moon is populated by 26 domed colonies connected to each other by canyons that function as supply routes.
The player must land in the canyons using Lunar Lander-style controls to search bases and ruins for the stolen ICE crystals.
To win the game, the player must "develop a pattern of play, alternating between exploring the canyons for valuables and the ICE and returning to the cities for repairs and trading."
[2] A Macworld review commended the game's "humanitarian goals" with killing "limited to machines" and combat secondary to moving essential goods to dying cities.
Success depends upon making trading decisions based on changing commodity needs, weighing the challenges in traveling to different destinations, and becoming skilled enough to pilot a craft overloaded with cargo while searching for the missing ICE crystals.
