A clone of missile command made with Unity
Missile Command is a 1980 arcade game developed and published by Atari, Inc. and licensed to Sega for European release. It was designed by Dave Theurer, who also designed Atari's vector graphics game Tempest from the same year. The 1981 Atari 2600 port of Missile Command by Rob Fulop sold over 2.5 million copies.
The player's six cities are being attacked by an endless hail of ballistic missiles, some of which split like multiple independently targetable reentry vehicles. New weapons are introduced in later levels: smart bombs that can evade a less-than-perfectly targeted missile, and bomber planes and satellites that fly across the screen launching missiles of their own. As a regional commander of three anti-missile batteries, the player must defend six cities in their zone from being destroyed.
The game is played by moving a crosshair across the sky background via a trackball and pressing one of three buttons to launch a counter-missile from the appropriate battery. Counter-missiles explode upon reaching the crosshair, leaving a fireball that persists for several seconds and destroys any enemy missiles that enter it. There are three batteries, each with ten missiles; a missile battery becomes useless when all its missiles are fired, or if the battery is destroyed by enemy fire. The missiles of the central battery fly to their targets at much greater speed; only these missiles can effectively kill a smart bomb at a distance.
