Be quick to redeem all Undead Mayhem codes and grab free Zombux and more!

Destroying zombies in Undead Mayhem is a lot of fun. You can either shoot them with guns or beat them up with a bat, but they’ll still keep coming. Each new wave gets more challenging, but that means you’ll get more Zombux and XP if you win.

Zombux is the main currency in this game, and you get it by eliminating zombies. If that becomes too challenging, you can get more by redeeming Undead Mayhem codes. This way, your hero can get XP buffs and free money, which will prove useful in surviving the zombie apocalypse.

Why are my Undead Mayhem codes not working?

If you experience an error while inputting Undead Mayhem codes, check for typos first.
