Barrage is a Missile Command variant where the player has to prevent the fiendish Draks from dropping acid balls on a planet. The player commands two laser gun towers at both sides of the screen to aim at and destroy the small dots coming down from above. You have to protect the vehicles and buildings on the ground. Each attack round gets more difficult and faster, and the guns are rebuilt and restocked with limited ammo. The game includes a single player mode, cooperative mode and competitive two player mode.
