You are under attack from above and must survive using only your trusty machine gun. Destroy as many enemy helicopters as you can. The goal is to see how many points you can obtain. Heli Attack 1 by Squarecircleco is the first game of the Heli Attack series. It is much simpler than its successors, featuring a single screen in which the player character accrues points by shooting an indestructible helicopter until the player runs out of health. With the exception of the Squarecircleco's sound logo which plays before the title screen, the game featured no sound.
