Hyper Dyne Side Arms, also known as Side Arms Hyper Dyne or simply as Side Arms, is a horizontally scrolling shooter developed and released by Capcom as an arcadevideo game in 1986.
In this cooperative game each player takes control of one of two flying mecha suits (Mobilesuit Alpha and Mobilesuit Beta) and must battle an alien army. Side Arms uses a two-directional attacking system similar to Capcom's previous shoot-'em-up Section Z.
