Mobile 3D Action Game Development

I’m building a mobile-first 3D action game and need an experienced developer who can take the project from early concept to a polished, store-ready build. The vision is a fast-paced experience with realistic graphics that run smoothly on both iOS and Android. I already have core gameplay ideas sketched out; what I’m missing is the technical and artistic horsepower to bring them to life. You’ll be handling scene setup, character and environment creation, gameplay scripting, UI, and the overall optimisation pipeline—everything necessary to produce a visually striking yet performant title. Unity or Unreal Engine expertise is welcome as long as the final APK/IPA hits stable frame rates on mid-range devices. Deliverables: • Playable vertical slice showcasing one complete level, core combat loop, and touch controls • Optimised 3D assets (characters, environments, VFX) that meet mobile performance budgets • Source project with structured, commented code and clear build instructions Acceptance criteria: • Sustained 60 FPS on devices equivalent to iPhone 12 / Galaxy S21 or better • All textures, meshes, and shaders use mobile-friendly sizes and LODs • No critical crashes or memory leaks after 30 minutes of playtesting If you have shipped a mobile action title with realistic visuals before, I’d love to see it and discuss how we can push this project forward together.
