Galactic Attack is a 1980 space combat simulator video game written by Robert Woodhead for the Apple II and published by the company he co-founded, Siro-Tech.

Siro-Tech was renamed to Sir-Tech and followed-up Galactic Attack with the more commercially successful Wizardry which was inspired by the PLATO system dungeon crawl games Oubliette and Moria.

In Galactic Attack, the player's job is to liberate the solar system from the dreaded Kazanta invaders by destroying the Kzanta's ships and bombarding the Kzanta's forces on the planets of the solar system and then beaming down armies to secure the planets.

Ships have phasers which fire in a cone, with damage proportionate to distance, a limited number of torpedoes that can be in flight at any given time and which proceed in a straight line until they hit a target or time out, deflector shields, a range of warp speeds, and a limited energy supply that slowly automatically regenerates.
