3D Survival Mobile Game Creation

I want to bring to life a cross-platform survival game in the spirit of the recent “Whiteout Survival” ads. The project targets both iOS and Android from day one and must feel native on each store.

Core Vision
• 3D graphics that deliver the same cold, rugged atmosphere shown in the ad, optimised for mid-range devices without sacrificing visual punch.
• Engaging survival mechanics: temperature, hunger, shelter, and day-night cycles that constantly pressure the player.
• Deep yet intuitive resource-management loop covering gathering, crafting, base upgrades, and worker assignment.

Scope of Work
You’ll take the concept from paper to a test-ready build. That means creating stylised low-poly assets or integrating stock packs where it saves time, setting up the gameplay systems in Unity or Unreal, and wiring basic analytics so I can fine-tune balancing. A simple login-free architecture is fine for this phase; multiplayer can wait for a later milestone.

Key Deliverables
1. Playable beta (APK + TestFlight build) featuring one biome, core survival loop, and progression to day 10.
2. Art package: all 3D models, textures, animations, and shader graphs in organised project folders.
3. Source project with commented code and build instructions.
4. Short video walkthrough that demonstrates features and performance on a mid-tier phone.

Acceptance Criteria
• Stable 30 fps on devices equivalent to iPhone 8 / Galaxy A50.
• No blocking bugs that reset progress.
• Balancing sheet exported as CSV so I can tweak numbers without a re-build.

Unreal or Unity are both acceptable; let me know which engine you prefer and why. I’m ready to review early prototypes as soon as you have the first week-night cycle running.
