Displayed prices
Prices come directly from your app store and are displayed in your currency.
Subscriptions
A subscription automatically applies to all your missions: the amount displayed at the end of an incident already includes the multiplier. It stacks with boosters and event bonuses. Management (renewal, cancellation) is handled through your app store.
Good to know
Gems do not replace credits: they save you time, but cannot be used to buy buildings or vehicles directly.
