Chopper I is a vertical-scrolling shoot ’em up released in 1988 for Arcades. Developed by SNK, you take control of an infiltration helicopter flying behind enemy lines to destroy heavily armed military bases. The gameplay is classic arcade action, requiring you to weave through intense enemy fire from tanks, jets, and gunboats while picking up power-ups to upgrade your primary weapons and bombs.
How to Play
The objective is to survive each stage and defeat the boss at the end, flying continuously upwards. By default for Arcade games in the browser, insert a coin with Shift and start with Enter. Use the Arrow Keys to pilot the helicopter, press Z to fire your machine gun, and X to drop bombs on ground targets.
Tips
- Your bombs are essential for destroying ground-based enemies like turrets and tanks before they can fill the screen with projectiles.
- Focus on gathering weapon upgrades early; increasing your spread shot makes it significantly easier to deal with formations of smaller aircraft.
