Hyper Dyne Side Arms[a] is a 1986 side-scrolling shooter video game developed and published by Capcom for arcades.

There are five types of power-ups that can be acquired by the player: a speed upgrade, an orbital bit that will provide additional firepower with the standard gun, a shotgun that shoots in a fan-shaped range, a three-way shooter, and a mega bazooka launcher that fires a laser beam.

According to Takashi Tateishi, the composer for the PC Engine version, the port was actually developed by Capcom themselves, but published by NEC Avenue to avoid offending Nintendo.

There was also an improved port to the PC Engine CD-ROM, under the name Hyper Dyne Side Arms Special (サイドアーム・スペシャル).

Home computer versions of Side Arms were also released in Europe for the ZX Spectrum, Amstrad CPC, Amiga, Commodore 64, and Atari ST, which were published by Go!

In July 2022, Side Arms was also included in Capcom Arcade 2nd Stadium for Nintendo Switch, PlayStation 4, Xbox One and Microsoft Windows via Steam.

In Japan, Game Machine listed Hyper Dyne Side Arms on their February 1, 1987 issue as being the ninth most-successful table arcade unit of the month.

Mobichan has appeared in many console games released by Capcom during the early 1990s as a mode select cursor such as in the Super Nintendo Entertainment System version of the original Street Fighter II.

In Project X Zone 2, Baby Bonnie Hood from Darkstalkers summons Mobilsuits α & β during her single-unit super attack.
