About

Current World Status It has been about 3 years since the Ice Age began. Average surface temperature: approx. -40°C Certain polar and high-altitude regions: below -70°C Most major cities are buried under snow and ice. Food production has plummeted. Power and communications are extremely limited. Most human survivors live in massive underground bunkers. Flora and fauna adapted to extreme environments have appeared on the surface. Massive glaciers cover cities and mountain ranges, changing the terrain itself. Living organisms have evolved to suit these extreme conditions. Temperatures drop so sharply at night that staying outside for more than 10 minutes without thermal gear is life-threatening. Survival Bunker No. 7 A massive underground facility where seven AIs reside. Originally an AI research and national disaster response facility, it was converted into a human survival base after the Ice Age began. Main Facilities Central Control Room Manages global weather, satellites, power, and food status. Living Quarters Includes bedrooms, a cafeteria, and lounges. Power Generation Area Supplies power to the bunker using geothermal energy and small nuclear reactors. Equipment Room Stores Himalayan expedition-grade winter clothing, oxygen tanks, goggles, and climbing gear. Surface Entrance Consists of thick blast doors and airlocks. Access is highly restricted because opening a single door causes a significant amount of the bunker's heat to escape. However, there is one problem: there is no food left in this bunker. Therefore, someone must go outside to scavenge for it. Disasters: 「Whiteout」 The most common and dangerous disaster. Visibility drops to mere centimeters. Strong winds of 30–50 m/s. Snow and ice particles fly like blades, cutting the skin. Communication equipment becomes unstable. It is easy to lose one's sense of direction outdoors. Vehicles or buildings can be buried in snow within hours. Surface exploration is virtually impossible during a whiteout. Glacial Collapse A phenomenon where massive layers of ice accumulated on mountains or glaciers suddenly collapse. Thousands to tens of thousands of tons of ice pour down at once, creating shockwaves like a glacial tsunami. If it occurs near the bunker, the entrance may be completely buried under ice. Glacial Tsunami A massive wave caused by glacial collapse or the movement of giant ice masses. The sea being frozen does not mean it is safe. Seawater remaining under the ice is suddenly displaced, causing the ice sheet itself to move like a wave. This is a fatal disaster for coastal bunkers. Sudden Temperature Drop Even in a world that is usually -40°C, the temperature occasionally drops abruptly. Example: -40°C → -65°C Such changes can occur within a few hours. During these times: Battery performance plummets. Fuel viscosity increases. Mechanical failures occur. Metal structures contract. Frostbite risk for exposed skin surges. Avalanche Occurs as massive amounts of snow accumulate on mountain ranges after the Ice Age. Particularly in high-altitude regions like the Himalayas, giant avalanches can occur. What makes them more dangerous is that it's not just snow coming down; Ice + Rocks + Snow + Trees + Building debris All sweep down the mountain together.
