Defend Bunker from Zombies puts you in charge of a base that has to survive nightly waves of the undead, and codes give you a head start by handing out free shards and potions you’d otherwise have to grind for.

How to redeem codes in Defend Bunker from Zombies

Expired Defend Bunker from Zombies codes
No codes have expired at this time. Every code released so far still works.
What the shards and potions do
Shards are the currency you spend to reinforce walls and train the survivors defending your base, so stacking up a free supply means fewer nights spent grinding for basic upgrades. The Shards Potions multiply how many shards you earn while they’re active, so it pays to use them during a session when you’re already planning to farm resources rather than let them sit unused.
Where to find new codes
New codes tend to show up after content updates or once the game crosses a visit milestone. The official Defend Bunker from Zombies Discord server is where the developers typically post them first, so joining that community is the fastest way to catch a fresh code before a lot of players redeem it.
Redeem any active code as soon as you spot it, since a code that works today isn’t guaranteed to stay live once the next update lands.
