The player controls a helicopter armed with limited munitions, such as missiles, bombs, machine guns, and napalm. As the player requisitions them, computer-controlled tanks, infantry, engineers, mobile missile platforms, and vans round out available firepower.
The objective is to assist deployed units, with the player's helicopter, in their efforts to destroy an opposing base at the opposite end of the play area. The enemy possesses the same arsenal as the player, so tactics and convoy composition are vital. Only the van, which contains electronic warfare equipment, can achieve victory by coming into contact with the enemy base. Its armor is quite weak, so these units must be protected at all times.
