Knight Online mobil port

I want to bring the full PC experience of Knight Online to smartphones. The task is to convert the existing desktop codebase (client and server) into a mobile-friendly build that runs natively on both iOS and Android without losing the feel, look, or performance players expect from the original MMORPG. Key objectives • Preserve real-time multiplayer functionality, including party, guild, chat, and PvP systems. • Maintain high-quality graphics—models, textures, and visual effects should match or closely approximate the current PC assets while remaining performant on mid-range devices. • Rework UI, controls, and camera for intuitive touch interaction (tap, swipe, virtual joystick, on-screen buttons). • Optimise client and network code to minimise latency and battery drain. • Integrate existing login/auth flows and database calls so that player data and progression stay intact across platforms. Deliverables 1. Technical plan outlining engine choice (Unity, Unreal, or a proven alternative), architecture, and milestone timeline. 2. Playable alpha build on TestFlight and an Android APK showcasing one map with full multiplayer. 3. Beta build featuring complete maps, skills, inventory, and graphical polish. 4. Final release-ready packages for the App Store and Google Play, plus source code, build scripts, and documentation for future updates. Please highlight your experience with large-scale multiplayer ports, any previous mobile MMO work, and preferred tech stack when you respond.
