I need a developer who can take a location-based multiplayer game from concept to live release on both the Apple App Store and Google Play. The core loop is simple: players move in the real world, find hidden pins, and team up for collaborative missions. Essential gameplay details Alternate Reality (AR) Gameplay • Mode: real-time, location-based multiplayer • Interaction: collaborative missions and some PvP • Must-have features: in-game chat, shared objectives that track progress for every squad member, and push notifications that trigger instantly when a mission update occurs Scope of work You will write every line of code, configure the database and real-time backend, integrate GPS/Maps (MapKit + Google Maps), and prepare the builds for submission. I expect cross-platform parity and smooth performance on recent iOS and Android devices. Using a cross-platform stack (e.g., Unity, Flutter, React Native) is fine if it delivers native-quality results; feel free to propose the toolchain you prefer. Deliverables 1. Full source code with clear, commented structure 2. Cloud backend (Firebase, Supabase, or similar) set up under my accounts 3. CI/CD pipeline that produces production builds for both stores 4. Store-ready screenshots, icons, and privacy labels 5. Step-by-step deployment and maintenance documentation Acceptance criteria • New users can create an account, join a into the game and see pins on the map within 30 seconds of launch. • Chat messages reach all squad members in under 500 ms round-trip in a real-world test. • Collaborative mission progress remains consistent across devices after force-closing or switching networks. • Both builds pass App Store and Google Play review and are published under my developer accounts. I’m looking for a single, all-inclusive quote—keep it competitive. Serious, experienced mobile game developers only; please share one live store link to a similar project when you submit your proposal. I will provide exact game details once a general quote has been agreed on. All rights to the game will be owned completely by me.

Location based multiplayer game from concept to live release on Apple App Store and Google Play with AR gameplay, real time squads, chat, and push notifications. Success is new users seeing pins on the map within 30 seconds, chat under 500 ms round trip, mission progress staying consistent across devices, and both builds passing store review. First I will lock the core loop and tech stack, then stand up the real time backend with auth and squads and wire MapKit plus Google Maps with GPS pin sync. Do you want true AR overlays or map first with optional AR view, and is PvP required in the first release or post launch. Pitfalls are GPS drift and battery drain, real time sync conflicts after network switches, push notification delays, store review issues around location and background use, and backend cost spikes under load. I have shipped real time location based multiplayer apps with chat, shared objectives, and cross platform parity using a single codebase and cloud backend. I can start quickly and give a clear all inclusive quote after stack choice, happy to continue in chat, Danylo Podolskyi

Hi there! Location-based AR multiplayer games are exciting, but real-time syncing, collaborative missions, and push notifications can be tricky to implement. Without careful planning, issues like laggy chat, inconsistent mission progress, or GPS errors can ruin the player experience. I am an experienced mobile developer with expertise in cross-platform game development using Unity and Flutter, integrating real-time backends like Firebase or Supabase. I’ve built multiplayer features, in-game chat, collaborative objectives, and smooth location-based interactions, ensuring consistent progress across devices. I also handle full deployment pipelines for both iOS and Android, including App Store and Google Play submissions. My approach will be to develop the game with Unity or Flutter for cross-platform parity, integrate GPS/MapKit & Google Maps, implement real-time squad chat and mission tracking, and set up cloud backend for seamless multiplayer data. I will ensure smooth performance, sub-500ms chat latency, and proper CI/CD pipelines so builds are production-ready. Full source code, deployment guides, and store assets will be delivered, with all rights assigned to you. check our work https://www.freelancer.com/u/ayesha86664 Do you prefer Firebase or Supabase for the real-time backend, or should I recommend the best option for speed and scalability?

Hello, I understand you're looking for a developer to bring your location-based multiplayer game from concept to live release on both the Apple App Store and Google Play. This project presents several challenges, including ensuring real-time interactions, handling GPS integration for accurate location tracking, and maintaining cross-platform performance. To address these challenges, I propose using Unity as the development platform. Unity excels in creating seamless AR experiences and offers robust support for multiplayer functionality. For real-time interactions, I would integrate a cloud backend like Firebase, which can handle user accounts, chat features, and collaborative mission tracking efficiently. Additionally, I will implement a CI/CD pipeline to streamline the build process for both platforms, ensuring smooth updates and deployment. In my previous projects, I developed a similar location-based game where I faced challenges with real-time data synchronization and user engagement. I successfully integrated MapKit and Google Maps for accurate location tracking and used Firebase for real-time chat and user authentication, which allowed for instant communication among players. This experience has equipped me with the skills needed to tackle the complexities of your project effectively. I can start right now and can finish in a short timeline. Looking forward to your reply.

Hi there, I’m an experienced mobile game developer with a strong track record of delivering cross-platform, real-time, location-based games from concept to live release on both iOS and Android. I specialize in building multiplayer AR experiences with smooth performance, reliable backends, and polished user interfaces. Approach & Expertise: Cross-Platform Development: Unity is my preferred stack for native-quality AR and real-time multiplayer; Flutter or React Native also viable for lighter AR interactions. Real-Time Multiplayer: Implement squad-based collaborative missions with instant sync and chat, using Firebase Realtime Database, Firestore, or Supabase for backend state management. Maps & Location: Integration of MapKit (iOS) and Google Maps (Android) with accurate GPS tracking, geofencing, and live pin updates. Notifications & Chat: Push notifications and low-latency in-game messaging to keep squad members synced under 500 ms. CI/CD & Deployment: Automated pipelines for both stores, including build, testing, provisioning profiles, and privacy labels. I ensure that new users can join and see map pins in <30 seconds, collaborative mission progress is consistent across devices, and chat functions reliably in real-world conditions. I’ve shipped similar AR multiplayer games and can provide store links upon request. Let’s discuss exact game mechanics and timelines so I can finalize a precise, competitive proposal.
