TV Arcade I Space War Vertical Intercept on the RCA Studio 2

Vertical Intercept is a one-button game for two players. Each player controls a missile launcher on each side of the screen and in between them an enemy spaceship moves up and down.

The player's missile climbs when the player holds down the button and drops when he releases it. The game ends when the spaceship hits a marker at the top of the screen 8 times. Hitting the spaceship makes it reverse its direction, so the game can be prolonged.
