The player controls a spaceship and travels through the galaxy. Unfortunately, there are asteroids and aliens that threaten the player's life. . .
Missile War is a shooting game in which the only goal is to survive long enough to get a high score. The player is free to move the spaceship horizontally and vertically, firing head-on at obstacles entering from the right side of the screen. Points are awarded for knocking down obstacles and lost for exiting from the left side of the screen. There are three types of obstacles: asteroids, asteroids that split in two when shot, and high-speed spacecraft. It is important to shoot down enemy ships, and if an enemy ship goes off the screen, the player loses lives and points. There are no enemy bullets, so touching obstacles is the only way to die. The background is simple.
