Expeditions outside the bunker
Beyond the airlock the world is still there, in ruins. Each expedition is a small adventure in stages, with turn-based combat, radiation and loot.
Prepare well
Before leaving you need a mask with filters, rations and a weapon from the armoury. The better your gear, the further you will go. Some weapons and pieces need prior research in the lab.
Destinations and bosses
Empty streets, a hospital, a flooded subway, a cathedral: each destination is longer and more dangerous than the last and ends with a boss. If you fall you lose nothing permanently: you are only wounded for a while.
What you earn
Scrap, junk to dismantle, materials and, now and then, a diamond. There is a limited number of trips per day to keep the pace of the game relaxed.
