A top-down zombie-blasting horde game is a perfect fit for mobile devices as the gameplay is easy to get into. However, fans of this type of game will also quickly learn that the genre comes with lots of grinding. To pass through stages, careful strategy isn’t enough; you also need to level up gears often. You’ll want to redeem the free Gems, Blueprints, and Keys from these Zombie.io gift codes to make the grind more bearable. Unfortunately, you must reach a certain stage first before you can start claiming them.

We have confirmed that the codes listed above are the ones currently working as of writing. The redeem code feature is only unlocked after you’ve completed Stage 5 – Molten Core. However, it is easier said than done, especially for free-to-play players! You’ll need to raise your Power Level to at least Level 1,300 to clear Stage 5 comfortably. You can check your Power Level by looking at the number below your Profile Level on the top left side of the screen. Increasing the Power Level is done by equipping higher rarity gears, upgrading them, and leveling up Genes.
Zombie.io promotional gift codes are not case-sensitive and can be typed in lower and upper cases. We’ll update this article once new ones have dropped, but you can also head over to the game’s official channels for more. Such as the Discord server, Facebook, and X (Twitter) accounts.
