The game is played on a 20x20 grid superimposed on a map. The map’s terrain consists of various lakes, flatlands, caverns and mountains. Each player controls an army that consists of a variety of modern units depending on the scenario. Players set up their units any way they choose in their designed corner of the gameboard. A player may take four actions each turn but no piece may take more than two actions during a turn. Move, fire, rapid transit (move a piece in one’s own corner without using the dice), place a jet or pass are the possible actions. Units within range of each other undertake combat by rolling the appropriate six-sided or eight-sided die. The victory conditions are dependent upon the scenario.
