Vault 13

In Vault 13, you command an underground bunker after the surface fell silent. Advance day by day while water, food, power, and air stay scarce. Watch the command center for supply levels, facility tier, and stability before the next crisis hits. Upgrade wings on the facility deck: repair damage, raise room levels, and keep production running when morale slips. The council chamber tracks every resident—review profiles, ease conflicts, and respond when agitators push the vault toward collapse. Sudden crises force hard choices with lasting fallout. Your decisions feed the chronicle timeline so you can trace how one harsh morning shifted the bunker. Progress saves locally on your device; start a new survival cycle anytime from Settings when you want a clean slate. Built for short sessions or long campaigns: plan upgrades, survive hatch debates and power struggles, and see how many days…
