Armored Encounter! is a clone of Atari's Combat. Two players control tanks and try to shoot each other the most in a time limit of three minutes. Each tank has 20 rounds of ammunition. The last three rounds will change color, warning the player the ammunition is low. This game offers 12 variations, selected by the alphanumeric keys.
Sub Chase! features a Hawk hunter-killer jet against a Shark missile-launching submarine. One player controls the jet, which scrolls left, and the other controls the submarine, which scrolls right. While neutral ships sail on the water surface, the players have to shoot each other the most in a time limit of three minutes. Each hit on the enemy scores one point to the player and each hit on the neutral vessels subtracts one point. There are three game variations, selected by the numeric keys.
The game was released in Europe for the Philips Videopac as Air-Sea War / Battle.
