Dyger is a 1989 vertically scrolling shoot ’em up developed by the South Korean studio Philko Corporation. Set against the backdrop of an alien invasion in the 22nd century, the game puts players in the cockpit of a lone spaceship tasked with saving Earth. Notable for its dual-plane combat, you must simultaneously manage the airspace and bomb ground targets across various intense arcade stages. This specific version is “Korea Set 2,” an alternate regional ROM of the original arcade release.
How to Play
As an arcade title, insert coins using 5 and press 1 to start. Use the Arrow Keys to pilot your ship. The game relies on a twin-attack system: press the primary action button to fire your main lasers at airborne enemies, and use the secondary action button to drop bombs on ground installations like tanks and static turrets. Power-ups dropped by defeated enemies upgrade your main weapons and increase your speed.
Tips
- Keep moving: The screen can quickly fill with enemy projectiles. Constantly shifting your position prevents you from being boxed into a corner.
- Prioritize ground targets: Static turrets on the ground often fire at unexpected angles. Bomb them early to clear a safer flight path before dealing with the faster aerial drones.
