Build and Kill Zombies Codes (September 2026): Free Cash, Hacker Tokens, and More

Looking to give your zombie-slaying vehicle a serious boost without grinding for hours? Build and Kill Zombies codes are here to help, and we've got the full list of working promos for September 2026.

If you're new to this Roblox experience, the goal is simple: construct a vehicle that can plow through undead hordes for as long as possible. You'll need to balance speed, armor, and firepower, and that takes Cash. The codes below will inject your account with plenty of it, plus Hacker Tokens and even some handy items.

Here are all the active Build and Kill Zombies codes right now:

IAMPRO – 5,000x Cash [requires a best distance of 1,000 studs] ROBLOXCLASSIC – 1,500x Cash (expires September 26, 2026) SCIFI – 1,000x Cash (expires September 26, 2026) LASTHACKEREVENT – 2,500x Hacker Tokens [requires a best distance of 2,500 studs] (expires September 26, 2026) NEWBOSSNEXTWEEK – 1,500x Hacker Tokens (expires September 26, 2026) PAINTEVERYWHERE – 1,000x Cash, 1x Crossbow, 1x Mounted Gun (expires September 26, 2026) COMMUNITY – 1,000x Cash, 1x Small Engine, 1x Small Tank CashDrop – 500x Cash MOREFRIENDS – 2x Passenger Seats HACKER – 50x Hacker Tokens 1x1x1x1 – 150x Hacker Tokens

A few of these codes have an expiry date of September 26, 2026, so don't sit on them. The others don't have a listed expiration, but they could still be removed at any time. As always, we recommend redeeming everything as soon as possible.

Redeeming codes in Build and Kill Zombies is a breeze. Once you've finished the short tutorial, tap the SHOP icon on the left side of your screen. That opens the EXCLUSIVE SHOP menu. Scroll all the way down to the bottom, and you'll see an Enter Code text box. Type in your code and hit the REDEEM button. Codes aren't case-sensitive, so as long as you spell them correctly, you're good to go.

It's also worth noting that one code, CYBERHACK, has already expired. It used to give 2,500x Hacker Tokens, but it's no longer valid. More codes will likely expire over time, so keep an eye on this list.

These codes are a great way to get a head start, whether you're saving up for a new weapon or need a few extra Parts to upgrade your ride. So what are you waiting for? Redeem them now and show those zombies who's boss. Which code gave you the biggest boost? Let us know in the comments!
