I’m putting together a full-scale 3D adventure game for both iOS and Android and need a developer who can take the concept from first prototype right through to store release. The core loop is classic exploration: players journey through interconnected worlds, solve environmental puzzles, and unlock gear that pushes the story forward. Because long-term engagement is critical, I want in-app purchases woven naturally into progression—think cosmetic upgrades, special abilities, and chapter unlocks rather than paywalls that break immersion. Unity or Unreal Engine is fine as long as the finished build runs smoothly on current mid-range phones and tablets. I’ll supply a high-level narrative arc, character sketches, and a rough wireframe of the UI; you’ll translate that into production-ready 3D assets, intuitive touch controls, and polished animation. Key deliverables: • A playable vertical slice demonstrating one complete level with integrated IAP and save system • Optimised, clean source code with comments and prefabs organised for easy iteration • Final iOS (IPA) and Android (APK or AAB) builds ready for App Store and Google Play submission, plus store-listing assets • Brief technical doc explaining architecture, asset pipeline, and instructions for future updates Acceptance criteria: the test build must hit a consistent 60 fps on devices comparable to an iPhone 11 and Samsung A52, all IAP products pass sandbox validation on both stores, and touch gestures feel intuitive for new players within the first minute of play. If you have shipped a 3D mobile adventure before, especially one monetised with non-intrusive purchases, I’d love to see it.

Hi! I have shipped 3D mobile adventure games in Unity with IAP, save systems, and smooth 60fps performance on mid range devices before. I understand you need a complete production pipeline from prototype to store release. I will deliver one polished vertical slice first so you can validate feel and monetisation before full build begins. Can you share the narrative arc and UI wireframes so I can scope the asset pipeline accurately?

Hello, While I haven't shipped a 3D adventure game specifically, but i have shipped several mobile games and am highly proficient in Unity and C#, focusing on the technical backend you need: mobile optimization, secure data persistence, and verified store integration. IAP & Save Systems: Experienced in setting up secure player progression saves and store-validated in-app purchases. 60 FPS Optimization: Focused on draw-call reduction and object pooling to hit a stable 60 FPS on mid-range devices. Timeline Note: The total duration will depend on the final feature scope. 3 quick questions to lock down the scope: 3D Assets: Will you provide the 3D models/animations for me to integrate? Vertical Slice: How many puzzles or gear unlocks do you envision in this first test level? Thank you. Regards, Mehwish Tariq
