Your police stations will be more exciting thanks to permanent upgrades and characters that will bring new stats. You can spend some gems in buying the basic, advanced, or expert card packs.
They will randomly provide a certain number of card fragments that will unlock and level up some of the permanent features. Some of them will only be available after a specific level, but once you unlock a card, it will work in all your precincts.
To find these cards, tap on the card’s icon on the top right side of the screen. If you tap on the different cards, you can see the different enhancements that they provide. There, you will find a "Get Cards" button on the bottom left part of the screen.
