This product page is for a SAS: Zombie Assault 4 top-up. A top-up adds in-game premium currency, balance, or a redeemable digital item depending on the selected product card.

If you want to buy SAS: Zombie Assault 4 (SAS4) credit without waiting for a slow manual process, this store is designed for quick digital checkout and instant delivery where supported.

How the SAS4 top-up works

The exact delivery method depends on the item format shown on the selected product card. Some SAS4 top-ups may require account information such as a player ID, login, nickname, email, or another identifier used to apply the balance. Other products may be delivered as a digital code or activation instruction that you redeem yourself inside the game or related platform. Always enter the details exactly as requested at checkout.

• Choose the SAS: Zombie Assault 4 (SAS4) denomination you want.
