Straightforward winning conditions - the effort has been put into creating a varied and interesting terrain to play on, and tuning the computer players to present maximum challenge. Originally designed for 2 players (1+2) with computer player "Yellow Peril" getting in the way (it is set to attack the winning player). After dealing with him, you must overcome Computer Player 4 to access the major mineral deposits, without which you will probably face stalemate or defeat versus your opponent. I redesigned the scenario to allow a human to take over position 3 if desired. Each of the 3 starting positions have very different terrain around them. Each player should adopt a different strategy. Singleplayer also : Yes
