You can no longer stay in the bunker: food supplies are running low, the ventilation system is damaged, and radiation levels are rising every day. Nuclear winter brings extreme cold, and you have almost nothing to keep you warm.

Explore radioactive ruins in search of resources, food, and technology while defending yourself from zombies, frost, and radiation.

Process collected scrap into metals, electronic parts, plastic, glass, and other resources. Use them to craft complex parts, devices, weapons, equipment, consumables, and medicine. Gather and grow food.

Power your base: use various energy generation methods, create electrical grids, install storage batteries, and set up lighting and heating. Build a chemical station to purify water and produce biofuel, acids, and gunpowder.

To survive, you will need new technologies, as radiation penetrates deeper and deeper every day. Explore the ruined post-apocalyptic world in search of floppy disks with recipes. Restore damaged disks and use them in the auto-crafter to create advanced devices and equipment.

Combine gear into a single, more advanced piece to fit all necessary functions into limited slots. For example, combine heated thermal underwear with a bulletproof vest, then merge them with a radiation suit — this creates powerful armor that combines and enhances all properties while occupying only one slot.
