You find yourself trapped in a sealed-off town deep in the Far North. A secret experiment has gone catastrophically wrong, shattering reality into two realms: our world and the Other Side. Outside your underground base, enemies wait around every corner. Explore the city, collect resources, craft gear - but remember: panic is more dangerous than bullets. A creature hunts you by tracking your heartbeat. The higher your pulse, the closer IT gets. Begin your journey as a lone operative: upgrade your equipment, fortify your shelter, master both worlds, and fight for survival - until you unravel the city’s darkest secret. Big City A vast, snow-covered Soviet-era city with changing weather, day and night cycles, cunning enemies, ever-changing - and no two raids are ever alike. Every trip into the city is a unique experience. Get out in time… or lose everything. Gather and Survive Explore the massive city to scavenge for loot - ammo, medicine, gear, resources, and rare items. Bring it all back to the bunker and use it wisely to upgrade your equipment and shelter. The Other Side Battles aren't just in the real world - you can enter The Other Side and face a terrifying enemy face to face. Time here is limited by your air supply, but only here can you find the most valuable resources. A Monster That Senses Your Fear Watch your heartbeat - it can give you away! Once you panic, there's no escaping THE ENTITY. It's already on your trail. Can you stay calm when it matters most? Level Up and Prepare Earn experience and resources to upgrade your gear. Grow your abilities through a branching skill tree and shape your own playstyle. Every raid makes your character stronger. Complete Missions and Uncover Secrets Take on quests, talk to survivors, and piece together the truth behind the catastrophe. Which side will you choose - the military or the scientists? Or is the truth hidden in The Other Side? No matter your choice, remember: with every heartbeat, IT draws closer.Stay calm. And good luck!
