Us Firefighter: Rescue Games – Mobile Simulation
End-to-end design, development, and deployment of 'Us Firefighter: Rescue Games', a high-engagement 3D open-world firefighting simulation mobile game built with Unity 3D, featuring offline gameplay, custom vehicle physics, character customization, and 1M+ Google Play downloads.
Client Background & Strategic Objectives
DotCom aimed to capture the mobile simulation market with a compelling, accessible firefighting experience. The core objective was to build a game that balanced realistic emergency response mechanics with arcade-style accessibility, targeting a broad audience (Rated 12+). Delivering an offline-first mobile game capable of reaching 1M+ downloads required high performance on mid-tier Android hardware.

5 IntegrationsDevelopment Technology Stack
4 Core TechsAgile Sprint Breakdown & Execution Roadmap
Pre-Production, Core Physics & Grey-Boxing
Finalized GDD, established Unity project architecture, built fire truck acceleration/turning physics, dynamic fire particle systems, and grey-boxed the open-world map.
Asset Production, Customization & Mission Logic
Finalized 3D models and texturing for vehicles and city assets. Programmed the 'fireman dress' customization UI, mission waypoints, spatial audio, and dog mascot variant.
Optimization, Monetization, QA & Launch
Applied texture compression, occlusion culling, and memory profiling for 60 FPS on mid-tier devices. Integrated AdMob mediation, passed QA audits, and executed Play Store launch.
Financial Matrix & Budget Allocation
| Development Phase | Budget Allocation | Strategic Justification |
