Radar

Radars are unlike the other upgrades the player can use; Radars can potentially increase the Mars Dollar income for the player by listing (if any) volcanoes, ruins, settlements, and homesteads available within the radar's vincity.

Radars only have 4 levels, can be purchased with real money, and level 1 radar costs 3500 Mars Dollars.

With each upgrade, the radar's vincity increases. The radar lists what's in the vincity by the first letter of the area.

H=Homestead S=Settlement V=Volcano R=Ruin O=Outpost D=Dunes P=Plains C=Crater
