I’m building an open-world game for Android and I now need a complete, production-ready level created in Unreal Engine 5.5. The playable area must span roughly 2 000 × 2 000 metres and present a believable desert environment—dunes, rocky plateaus, sparse vegetation, weather-worn ruins, whatever sells the arid mood—while still running smoothly on mid-range phones without hangs or lag. Because combat is the core mechanic, lay out the terrain to encourage firefights: natural arenas, flanking routes, cover objects, and enemy spawn volumes. I don’t want grey boxes or temporary props; every asset included should be final-quality yet fully optimised for mobile. That means sensible texture sizes, LOD chains, instanced foliage, Nanite where it makes sense, and mobile-friendly lighting (no heavy Lumen). Deliverables • A UE 5.5 project with the desert landscape, all meshes, materials, and level logic in place • Performance hitting a steady 30 FPS (or better) on a typical Android test device • A brief optimisation report describing the settings and techniques you used When you place your bid, please give me the total cost to deliver everything above and let me know how long you’ll need. No placeholder bids, please—I’m ready to move forward as soon as we agree on scope and price.
