BUNKER PROTOCOL: Reactor Core

You wake up alone in a sealed underground shelter. The door is locked. The lights flicker. Your only way out is to solve every puzzle the bunker throws at you. BUNKER PROTOCOL: Reactor Core is a fully 3D escape room experience designed for mobile. Explore every corner of a detailed underground bunker, examine objects, collect items, and piece together the solution to escape. FEATURES - Immersive 3D Environment: Explore a richly detailed underground bunker rendered in full 3D. Rotate your view, walk around, and examine objects up close. - Multiple Interconnected Puzzles: Solve a sequence of brain-teasing challenges, from valve alignments and symbol safes to wire repairs and cipher dials. Each puzzle unlocks the next. - Observation-Based Gameplay: Every clue you need is hidden somewhere in the shelter. No trivia, no outside knowledge required. Just look, think, and solve. - Item Collection & Combination: Pick up tools and key items scattered throughout the bunker. Combine them to create new solutions and unlock hidden mechanisms. - Sequential Puzzle Progression: Puzzles unlock one by one in a carefully designed order. Restore power, crack codes, repair circuits, and ultimately find your way to freedom. - Hint System: Stuck on a puzzle? Use the built-in hint system to get a nudge in the right direction without spoiling the full solution. - Multilingual Support: Play in English, Japanese or Russian with full localization. - No Ads Interrupting Gameplay: No banners, no interstitials. The only ads are optional rewarded videos when you choose to view a hint — your immersion is never broken.

Examine everything, collect useful items, and solve puzzles in sequence. Each solved mystery brings you one step closer to escaping the bunker. THE CHALLENGE The bunker holds many secrets. A locked terminal. A sealed door. Valves that need the right sequence. A safe with mysterious symbols. Wires that need mending. Can you piece together every clue and find your way out?
