I want to create a fast-paced, first-person action game designed specifically for mobile devices. The core idea is to deliver tight, responsive controls and quick session gameplay that fits touch screens without compromising the excitement normally found on console shooters. Scope The project covers everything from initial concept art to a playable build ready for App Store and Google Play submission. I already know the key pillars—Action genre, Mobile platform, First-person view—so I’m counting on you to translate those pillars into engaging mechanics, intuitive UI, and optimized performance for a broad range of handsets. Key Objectives • Build a small but replayable first-person action loop (think 3–5 minute levels). • Design touch-friendly controls with optional gyro aiming. • Implement lightweight progression (unlockable weapons or abilities). • Optimize file size and frame rate for mid-tier Android and iOS devices. • Integrate basic analytics and in-app purchase hooks so I can tweak monetisation later. Preferred Tech Unity or Unreal Engine is fine; use whichever you are fastest with and that best suits mobile deployment. If you choose Unity, I’d like URP; if Unreal, please configure for mobile forward rendering. Git or similar version control is mandatory so I can follow progress. Deliverables – GDD summarising core mechanics, art style, and monetisation loop – Playable alpha (one arena, one enemy type, weapon prototype) – Beta with full touch UI, audio, and first round of optimisation – Release candidate ready for store submission, including icons, screenshots, and compliance checklists – Source project + build instructions Acceptance Criteria • Stable 60 fps on iPhone 11 / Pixel 4 or equivalent • No crashes during a 30-minute playtest • Touch controls pass a simple two-finger test without ghost touches • All assets and code are free for commercial distribution or properly licensed If you have a completed mobile FPS in your portfolio or experience repurposing console-style action for touchscreen, let me know; it will help me pick faster.
