Fusionist stands as an independently developed AAA game, leveraging the Unity engine with HDRP (High Definition Render Pipeline) for achieving top-tier visual effects. The networking component incorporates real-time synchronization technology (KCP + flatbuffer protocol), while backend computation exclusively determines all outcomes to eliminate any potential for cheating. Furthermore, a lightweight client has been crafted using Unity WebGL technology, enabling seamless compatibility with PCs and mobile devices to broaden user accessibility to the maximum extent possible.
