Capture the Flag!
The object of the game is to capture own both your flag, and your opponent's flag at the beginning of your turn. Do so, and win.
Each player will control 5 units on the board at all times. Should a unit be attacked, it will be removed from the field. Depending on where the unit was located when it was removed, it will respawn in a specific location. If the unit was removed within the player's defending area, that unit will respawn at that player's base. If the unit was removed outside of the defending area, the player will respawn in jail. Respawn takes 2 turns.
Player 1's defending zone is everything from the hills to the western edge. Player 2's defending zone is from the stream to the eastern edge. All areas inbetween are considered no-man's land, and units removed here can be taken to jail.
