Getting to Know SideArms - Hyper Dyne (Japan)

Compiled by the Retro Games Online Editorial Team · Updated June 27, 2026

SideArms - Hyper Dyne is a horizontally scrolling shoot 'em up originally developed by Capcom for arcades in 1986. This port arrived on the NEC TurboGrafx-16 (PC Engine) exclusively in Japan in 1989, published by NEC Home Electronics. It's a straightforward translation of the coin-op experience, bringing the same fast-paced action to home consoles without major revisions.

Players pilot the Hyper Dyne mech through six stages, blasting waves of alien enemies while collecting colored power-up capsules to upgrade their weapon. The game alternates between ground-based walking sections and airborne segments where the mech can fly freely. Each stage ends with a boss encounter that demands pattern recognition and precise dodging. The core loop involves clearing enemy waves, gathering upgrades, and surviving until the stage boss.

This import-only release is a competent port of a Capcom arcade classic, though it lacks the two-player simultaneous mode found in the original arcade cabinet. For TurboGrafx-16 collectors, it's a decent but not essential shooter, sitting alongside games like Gunhed and Blazing Lazers. Its straightforward arcade roots make it easy to pick up, but the challenge escalates quickly, keeping it engaging for fans of the genre.

How to Play SideArms - Hyper Dyne (Japan) Online

When you boot the game, the title screen appears in Japanese. Press the Start key (Enter) to begin. You control the Hyper Dyne mech with the D-pad: move left, right, up, and down to dodge enemies and position yourself. Use the S key (B button) to fire your weapon. The X key (A button) lets you jump, which is useful in ground sections to avoid incoming fire. As you defeat enemies, they sometimes drop colored power-up capsules. Collecting two capsules of the same color upgrades your current weapon to a more powerful version; mixing colors changes your weapon type.

The game proceeds through six stages, each with a boss at the end. Your goal is to survive and reach the final confrontation. The menus and any configuration screens are entirely in Japanese, but typically you only need to press Start to skip them. If you see a screen with options, pressing Start again usually begins the game. The core loop is straightforward: shoot everything, collect upgrades, and learn enemy patterns to survive the escalating difficulty.
