Hyper Dyne Side Arms (サイドアーム) is a 1986 side-scrolling shoot-'em-up arcade game developed by Capcom. 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. As either Lt. Henry or Sgt. Sanders, the player must pilot a giant space mecha known as a "Mobilsuit" to defeat the aliens. Up to two players can play simultaneously.
The controls consist of an eight-way joystick for moving the Mobilsuit and three action buttons. Side Arms uses two shooting buttons, one for shooting to the left and the other to the right. The third button is used to change between the weapons acquired by the player. 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 with shoots in a fan-shaped range, a three-way shooter, and a mega bazooka launcher that fires a laser beam. The player can choose what power-up their mecha will receive by shooting the power-up icon until getting the item they want. All of the weapons, as well as the mecha's speed, can be upgraded up to two or even three levels depending on the item. There is also a speed downgrade that will reduce the Mobilsuit's speed by one level. There are also two "Auto" power-ups, shaped like the enemy characters from Vulgus: one is shaped like the "Yashichi" and allows the player to fire continuously with either firing button held down; while the other, which is shaped like the "Sakichi", allows the player to shoot upwards, downwards and forwards at the same time, but at a slower rate than the regular shot.
In addition to the standard power-ups, there are two special combination power-ups shaped like the Greek letters α and β that will combine the player's Mobilsuit with an ally. This allows the player to do an eight-directional attack at the same time as their regular attack. When two players are playing this power-up will combine both players' suits instead. One player will move the combined suit and perform the regular attack, while the other will provide the eight-directional attack. If the combined suit gets shot by an enemy soldiers, it will revert both suits into their regular separate states.
Side Arms was released for the PC Engine on July 14, 1989 in Japan by NEC Avenue. This version differs from the arcade game in which it allowed player to change weapons through a sub-menu while pausing the game. However, the PC Engine version lacks the 2-player feature from the arcade game. This port was published in North America during the same year by Radiance Software.
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). This version features a new "Before Christ" mode with various changes to gameplay.
Appearances in other games
A "chibi" version of the player's Mobilsuit, called "Mobichan", appears in the game as a power-up item that gives the player an extra life. 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. The arcade game Warriors of Fate features a hidden ending sequence for completing the game on one credit which shows Mobichan and its Player 2 counterpart fighting against each other dressed Ryu and Ken and using their special techniques against each other.
Mobichan is saving icon for Street Fighter Collection (Super Street Fighter II and Street Fighter Alpha 2 Gold) for the PlayStation.
It also makes an appearance in Asura's Wrath (Episode 5 intro).
In Mighty Final Fight, Mobichan is seen on continue screen.
In Street Fighter Alpha 2, when player wins by the means of a taunt, Mobichan will be seen as win symbol.
In Warzard, if you beat the game with one credit you will be able to control Mobichan in credits sequence and shoot down the letters. Mobichan is also symbol that can be used when entering a password.
