Maps
Vehicles, helicopters, airplanes, and airships can be transported to other maps via highways. The highways are located at the edge of the map. Boats reach other maps through the river at the edge of the map, and trains via the tracks at the edge of the map. Relocating units to other maps costs fuel, with 20% of the used fuel being carried along. To relocate units to other maps, sufficient military headquarters and an adequate group limit on all maps are required.
