Shop

The shop is a place where you can buy guns, hacking upgrades, base upgrades, cash injections, access teams and buy premium.

Guns
Guns are weapons in the game that allow you to kill others and break into bases. You can buy guns at the shop when you have enough funds. You start off with the HK MP7 and the M9. You can buy other guns such as the Jungle Carbine when you gather enough money. Weapons are permanent.

Hacking
Hacking consists of Wallets and Tools.

Wallets are items that can store Crypto, the main currency. They have a limit, and if you reach that limit, you can't get any more crypto into your wallet, thus causing you to go back to your base and depositing it. Tools are items that boost how fast you get Crypto deposited into your wallet and bonus. Tools are unlocked every 5 levels except for when you join the game. To get crypto inside your wallet, you need to go closer to the Atm,computer or anything having crypto stored in.
