Thunder Dragon Bootleg No Sound is a modified arcade release of the 1991 vertically scrolling shoot ’em up originally developed by NMK. Players pilot the titular combat helicopter through eight stages to stop a group of rogue scientists. As the title indicates, this specific bootleg version runs without audio, but it fully retains the intense bullet-dodging and classic arcade action of the original game.
How to Play
Your objective is to survive waves of enemy aircraft and ground forces, defeating a massive boss at the end of each stage. In the browser, use the arrow keys to maneuver your helicopter. Press Z to fire your primary weapon and X to deploy a screen-clearing bomb. Use Shift to insert a virtual coin and Enter to start.
Tips
- Pay attention to the numbered power-up canisters (1 through 4) that appear. Each number provides a different weapon typeโsuch as wide shots, lasers, or missilesโso grab the one that best suits your playstyle.
- Bombs not only deal heavy damage but also clear the screen of incoming bullets. Save them for boss encounters or when you are completely boxed in.
