The Enemy is attacking your borders and you must withstand the three waves of invasion heading your way. You must choose and deploy your units to destroy the Invader before it eliminates them all. This dice game is a solo version of co-ordinate based battle games, like Battleships or Salvo. You choose which Units to use - Bunkers, Guns, Tanks and Command. Then deploy them on the grid to outlast the attack of the Invader. Near misses result in bombardments that cover multiple grid points, so a well thought out deployment is essential. You need to survive three waves of attack to win the game.
