A coin-op game released by Capcom/Romstar in 1986. The full title was Sidearms Hyperdyne in the U.S. and Hyperdyne Sidearms in Japan. Sidearms was a very underated and somewhat rare shooter/shmup with a Robo-Tech type theme. The game featured both 1 and 2 player simultaneous action, horizontal and vertical scrolling, several stages ranging from moderate to downright difficult, challenging and sometimes huge bosses, a special power-up that unlocked a dual mecha transformation and other bonus features. The game was ported mostly to computers such as the Atari ST, and Commodore 64 as well as the PC-Engine/TurboGrafx-16 and also Sony's PSP in a Capcom compilation. Sidearms was the second game in a series known as "Jetpack Hero" which started with Section-Z and ended with Forgotten Worlds. They are related only in that they have a similar layout and gameplay; each game in the series has it's own storyline.

Sidearm is a z-80? based arcade game from the late 1980's featuring 2 dimensional scrolling, and interchangeable weapons.

Sidearm Frisbee, a Frisbee throwing technique, placing the disc between the thumb and first two fingers then throwing from the side. (similar to a sidearm baseball throw)

Ken Westerfield's sidearm distance record of 552 feet, with a 119 gram World Class Model Frisbee, Boulder Colorado 1978, and Victor Malafronte's, 538 feet also with a 119 gram Frisbee, not only have the longest sidearm throws of all time but are the best sidearm throwers of all time.

At a North American Series (NAS) Frisbee tournament in Dallas Texas, Westerfield became a member of the "400 club" with a prelim distance sidearm throw, and won the event with a throw of 378 feet, using a 119-gram World Class Model Frisbee. Only two competitors have officially ever thrown over 400 feet in competition with a 119-gram Frisbee (Lightweight disc by today's standard).

1978, in Boulder, Colorado, while doing a distance throwing demonstration at a North American Series (NAS) Event, Westerfield threw a sidearm 119-gram World Class Model Frisbee, 552 feet, shattering the official world distance record of 412 feet

Tournament officials marked and measured the throw at 552 feet. Since the introduction of heavy weight, sharp edge disc, the world record is now over 800 feet. However Westerfield's 552 feet is still the record for the sidearm throw

1) in lacrosse, a chief who refuses to shoot overhand even when it would be more convenient to do so. a sidearm guy always shoots sidearm because he thinks it looks cool.

2) in life, anyone who insists on doing everything in a lazy or inappropriate manner. They wear hats cocked at stupid angles and leave trash all over the floor. this is derived from definition 1), as sidearm guys translate their sidearm ways into an entire lifestyle.
