Chopper Command Atari 2600 (Activision) 1982

Chopper Command is a horizontally scrolling shooter released by Activision for the Atari 2600 in 1982. It was written by Bob Whitehead. The player flies a helicopter left and right over a scrolling, wraparound landscape, shooting down enemy airplanes to protect a convoy of trucks below.
In Chopper Command, the player controls a military helicopter in a desert scenario protecting a convoy of trucks. The goal is to destroy all enemy fighter jets and helicopters that attack the player's helicopter and the friendly trucks traveling below, ending the current wave. The game ends when the player loses all of his or her lives or reaches 999,999 points. A radar, called a Long Range Scanner in the instruction manual, shows all enemies, including those not visible on the main screen.
The player's helicopter is destroyed if it collides with an enemy aircraft or a truck or if it is shot by an enemy bullet. The enemy bullet splits in two one going up and one going down. Using the "A" difficulty level results in a slower player shot.
Each enemy helicopter is 100 points and each enemy jet is 200 points. After each wave, bonus points are awarded for remaining trucks.
A player who achieved 10,000 points could send in a photo of the TV screen and receive a "Chopper Commandos" patch.
