Scrap and diamonds
Two currencies, one rule: no randomness. In the bunker you always know what you earn and what you pay.
Scrap is earned by playing
Scrap is the in-game currency. It is earned by doing tasks, completing missions, with the daily streak and with the automatic scrap collector. It is used to recharge vital systems, buy upgrades and redeem some decorative items. It cannot be bought or exchanged for money.
Diamonds: the booster
Each diamond divides the time left on a bunker job by ten and refills your stamina in the mine. They are found by playing (in the mine, missions, the weekly streak and expeditions) and can also be bought in packs.
Clear purchases
Warehouse decorations give no gameplay advantage. There are no loot boxes, raffles or random items: you see what you buy and what it costs, VAT included. Purchases are only for people who meet the minimum age, with daily and monthly limits you control in your account.
