Computer War is a single-player strategy, simulation, casual, and arcade game in which players engage in a two-part gameplay involving puzzle-solving and action elements. In this game, players must decode a computer message to launch missiles and then actively guide interceptors to defend cities from incoming enemy missiles, set in a tense thermonuclear war scenario. It stands out with its unique combination of puzzle mechanics, where players rotate pieces in a grid to match a target figure, and real-time action, where players control interceptors to shoot down enemy missiles, creating a dynamic and engaging experience across multiple platforms including Commodore VIC-20, Atari 8-bit, ti-99/4a, vic-20, and Texas Instruments TI-99.
