The game was also released to the TurboGrafx-16, as well as to various home computer platforms. In Side Arms the player takes control of a flying mecha suit who must battle an alien army. Side Arms uses a two-directional attacking system similarly to Capcom's previous shoot-'em-up Section Z. An evil alien empire known as the Bozon are launching a full-scale attack on Earth.
