Mobile Multiplayer Open-World Roleplay Game

About the project

Multiplayer Open-World Mobile Roleplay Game I am looking for an experienced game development team to build a high-quality multiplayer open-world roleplay game for iOS and Android. The game should feel like a living online city where real players interact, choose careers/lifestyles, earn money, own vehicles/property, join factions, commit crimes, work legal jobs, and progress over time. I am not looking for a template, reskin, basic simulator, or low-quality prototype. I want a strong foundation for a serious long-term online game. Graphics / Visual Quality Graphics are very important. I want a modern realistic 3D style comparable to high-quality mobile open-world games, while still being optimized for smartphones. Desired visual features: * Detailed city environment * Good lighting/shadows * Day/night cycle * Weather * Quality character models * Character customization * Smooth animations * Detailed vehicles * Vehicle lights and basic damage * Important building interiors * Modern premium UI * Adjustable Low / Medium / High / Ultra graphics Performance and optimization on modern iOS and Android devices are extremely important. Map / World The first version does not need a huge map. I prefer a smaller, detailed and active city instead of a massive empty world. Potential locations: * Downtown * Residential areas * Luxury district * Industrial area * Police station * Hospital * Government buildings * Vehicle dealerships * Garages * Fuel stations * Banks * Shops * Restaurants * Apartments/houses * Prison * Highways * Airport area * Countryside/desert areas The map, assets and identity must be original or properly licensed. Multiplayer Multiplayer is the core of the game. Players must be able to interact with other real players in a persistent world. Required architecture should support future scaling. Features: * Player synchronization * Vehicle synchronization * Interaction synchronization * Text chat * Proximity voice chat or recommended voice solution * Private/faction chat * Player IDs/names * Reconnection support * Persistent accounts Important gameplay systems should be server-authoritative wherever possible. Accounts / Persistence Player progress must be stored permanently. Stored data should include: * Cash/bank balance * Character * Clothing * Vehicles * Inventory * Jobs * Faction/rank * Property * Licenses * Punishments * Businesses * Progression The backend/database must be secure and scalable. Character System Character customization should include: * Gender * Face * Hair * Skin tone * Clothing * Accessories * Facial hair Movement should include: * Walk * Run * Sprint * Jump * Crouch * Enter/exit vehicles * Sit * Interaction animations * Handcuff animations * Weapon handling later Controls must be comfortable on mobile. Vehicles Vehicles are a major part of the game. Categories can include: * Sedans * SUVs * Sports cars * Supercars * Pickups * Motorcycles * Police vehicles * Emergency vehicles * Commercial vehicles Vehicle systems: * Buy/sell vehicles * Ownership * Garage * Keys * Lock/unlock * Fuel/refueling * Damage/repair * Impound * Registration/license plates * Paint customization * Wheels * Performance upgrades later Driving should feel enjoyable and reasonably realistic. Economy Persistent economy including: * Cash * Bank * Player payments * Salaries * Purchases * Fines * Vehicle purchases * Property purchases * Job income * Business income * Criminal income Prices and economy settings should be adjustable server-side without requiring a full game update. Jobs Legal jobs may include: * Taxi * Delivery * Trucking * Bus driver * Mechanic * Tow truck * Courier * Garbage collection * Construction * Fishing/mining Jobs should support progression and different rewards. Police Police should be a major faction. Features: * Police ranks * Duty system * Uniforms * Police vehicles * Equipment * Player/vehicle search * Handcuffs * Arrests * Fines * Jail * Impound * Wanted system * Police radio * MDT/police computer * Traffic stops * Rank-based permissions EMS Future EMS system: * Ambulances * Medical uniforms * Revive/treatment * Hospital * Emergency calls * EMS ranks/radio Criminal Gameplay Potential systems: * Robberies * Illegal items * Vehicle theft * Black market * Gangs * Gang territories * Police pursuits * Wanted status * Prison * Illegal missions * Criminal reputation These systems must be balanced to protect normal roleplay. Factions / Organizations Support multiple organizations such as: * Police * EMS * Government * Businesses * Criminal groups * Player organizations Faction systems should include: * Ranks * Permissions * Internal chat * Uniforms * Vehicles * Headquarters * Shared storage * Management controls Property / Businesses Future property system: * Apartments * Houses * Garages * Luxury properties * Buy/sell * Interiors * Storage * Keys * Invitations Player-owned businesses could include: * Restaurants * Dealerships * Garages * Shops * Taxi companies Business owners should eventually manage employees, salaries, permissions and income. Inventory / Phone Inventory should support items such as: * Food/drinks * Medical items * Tools * Documents * Keys * Weapons/ammunition later * Job items I would also like an in-game phone with possible features: * Contacts * Calls/messages * GPS * Bank * Jobs * Taxi * Emergency services * Marketplace * Settings Combat Potential later combat: * Melee * Weapons * Health * Armor * Knockout/death * Hospital respawn Combat and damage should use server-side validation where possible. Admin / Moderation A strong administration system is required.

Anti-Cheat / Security Please explain how you will protect against: * Speed hacks * Teleport hacks * Money modification * Inventory duplication * Fake purchases * Damage modification * Unauthorized items/vehicles * Client manipulation * Packet abuse Money, inventory, ownership and important gameplay logic should not trust the client. Monetization The architecture should allow future monetization such as: * Premium membership * Cosmetic clothing * Vehicle cosmetics * Character customization * Battle pass * Animations * Extra character slots * Cosmetic property items I do not want extreme pay-to-win gameplay. Technology I am considering Unity or Unreal Engine. Please recommend: * Best engine for this project * Multiplayer technology * Backend technology * Database * Hosting architecture * Voice chat solution * Expected server capacity * Scaling approach Development Phases Phase 1 – Core Prototype * Small city area * Multiplayer * Character movement * Vehicles * Accounts * Persistent database * Money system Phase 2 – RP MVP * Expanded city * Jobs * Police * Arrest/jail * Shops * Inventory * Dealership * Banking * Chat * Admin tools Phase 3 – Expansion * EMS * Criminal systems * Properties * Businesses * More jobs/vehicles * Character customization * More interiors Phase 4 – Launch * Optimization * Anti-cheat improvements * Monetization * Scaling * Events * Live operations Ownership / Deliverables I require: * Full game source code * Full backend source code * Database schema * Game project files * Server configuration/documentation * Admin tools * Build files * Access/control of infrastructure * Commercial rights to custom work produced All third-party assets/plugins/services must be disclosed, including recurring fees/licenses. The project must not depend on infrastructure controlled only by the developer. Proposal Please include: 1. Multiplayer/mobile games you have developed 2. Videos or playable examples 3. Proposed team size 4. Recommended engine 5. Recommended multiplayer/backend architecture 6. Development milestones 7. Estimated MVP cost 8. Estimated complete-project cost 9. Estimated monthly server cost 10. Expected concurrent player capacity 11. Mobile performance expectations 12. Source-code handover terms 13. Post-launch support options Please clearly state which systems you have personally built before. I am looking for a serious development team interested in a long-term online multiplayer project, not someone simply combining marketplace assets into a quick prototype.
