Why are my Undead Mayhem codes not working?

If you keep getting the “Code is invalid” message after trying to redeem your codes, check your codes’ spelling and casing beforehand or paste them straight from the codes section above into the redeem codes text box. On the other hand, getting the “Code is expired” message means you’re too late to redeem those codes.

What is Undead Mayhem?

Undead Mayhem is a third-person team shooter tasking you with defending the abandoned hospital from an invasion of the undead. The game lets you team up with three other players as you take on waves of zombies, each weave becoming more challenging. Every defeated zombie gives you cash to spend on weapon upgrades and ammo refills, and tougher zombies will also drop grenades and health refills. If you or your teammate gets injured, the other teammates have 60 seconds to revive them. Otherwise, the fallen teammate will have to wait until the end of the wave to respawn. To increase your chances of survival, keep building barricades and stick with your team. If you need more help, don’t hesitate to use Undead Mayhem codes. If you’re looking for codes for other games, we have many in our Roblox Game Codes post! You can also get a bunch of free stuff via our Roblox Promo Codes page.
