Zero Zone vs Downfall Survival Sim

Zero Zone turns your real runs into post-apocalyptic conquest. Every kilometer you run generates Scrap and Intel — resources you use to upgrade your base and claim hexagonal territory on a real-world map. Defend what's yours. Attack your rivals. Dominate the city. MOVE TO EXPAND Lace up and run. GPS tracks your route and converts your distance directly into in-game resources. The more you run, the stronger your base. BUILD YOUR BASE Spend Scrap upgrading your HQ and its buildings step by step. Unlock new abilities and cement your position on the map. CONQUER TERRITORY Use Intel to claim hexagons on the real city map around you. Expand strategically — every hex you hold strengthens your leaderboard position. BATTLE YOUR RIVALS Attack enemy hexagons using your Intel. Server-authoritative, probabilistic battles keep things fair. Push notifications alert defenders the moment their territory comes under attack. PRIVACY FIRST Your base doesn't have to be at your home address. Leaderboards show only a city tag — never your exact location. NO PAY-TO-WIN Zero Zone is free to play. Premium currency buys cosmetic skins only. No advantages for paying, ever.
