Kinmen Kill (金門殺) is a multiplayer battle royale game set in Taiwan's Kinmen islands, designed to realistically simulate FPV drone flying and combat to help prepare Taiwanese citizens for active defense against potential invasion. The core of the game emphasizes highly realistic physics, integrating BetaFlight directly into a custom-built 3D physics engine running at 8000Hz, matching BetaFlight's maximum gyro sampling rate, to closely replicate real FPV drone flight dynamics. We actively simulate advanced aerodynamic phenomena, such as ground effect, prop wash, and accurate drone response to piloting inputs, ensuring that in-game experience translates effectively to real-world FPV drone piloting. Available in Traditional Chinese and English, the game visually and narratively positions players as Taiwanese defenders against Chinese (CCP/PLA) adversaries, aiming to educate and motivate democratic self-defense tactics similar to Ukraine's drone warfare strategies.
