Real-world treasure hunt

Intercepted transmission: a new operation is live. Find the specimens. Beat the clock. Outplay every other operative. A location-based treasure hunt played in the real world. Specimens are hidden across the field — physical QR codes waiting to be found. Walk the map, scan what you discover, and watch your score climb. But your lead decays as other operatives catch up. First is fastest. First is cleverest. Proximity signals pulse harder as you close in. Sealed containment units need challenges solved before their Bluetooth locks will open. Trade specimens with rivals, form hives for score multipliers, and hide your best finds from the leaderboard — your true score is yours alone. When the clock hits zero, the highest-ranked operative takes the prize. Features — Map-driven outdoor gameplay with real-time proximity heat — QR specimen scans with procedural tier glyphs — Bluetooth lockbox challenges with riddle / trivia / puzzle gates — Trading between players with multi-tag N:M proposals — Hive formation for score multipliers — Live Activity on lock screen + Dynamic Island countdown — Haptic proximity feedback Designed for short, in-person events — your community runs the game.
