Side Arms Hyper Dyne is a classic 1986 horizontal scrolling arcade shooter developed by Capcom. Earth is under attack by the Bozon alien empire, and players control Lieutenant Henry and Sergeant Albert in heavily armed mecha suits to fight them off. As a spiritual successor to Section Z, it delivers intense sci-fi action where you can fire in both directions to take on waves of enemies.
How to Play
Your objective is to survive enemy waves, collect power-ups to upgrade your weapons, and defeat the boss at the end of each stage. Use the Arrow Keys to move your mecha. For arcade controls in the browser, press Shift to insert a coin and Enter to start. Press Z to shoot left, X to shoot right, and C to cycle through your available weapons. In two-player mode, the two mechas can merge into a single, more powerful unit.
Tips
- Master weapon switching: Different situations call for different firepower. Switch to the shotgun for wide coverage or the laser for piercing damage against heavily armored targets.
- Watch your back: Enemies constantly spawn from behind you, so be ready to use the dedicated left-attack button to clear your tail.
- Grab the Alpha power-up: Collecting the glowing “a” icon combines both players (or grants a special combined form in single-player) for a massive, multi-directional attack boost.
