Nightmare Defense Code Guardian

Renato Estrada

Code Guardian

Personally finds and maintains every code on this page, with around-the-clock help from the rest of our Code Guardians.

Roblox Den's code tracker continually scans Roblox.com, social channels, user reports, game developer networks and other sources, and we've had 730,651 reports from players on Works, Doesn't work and new codes. But before any code is listed on our site, or marked as Expired, our Code Guardians check in-game that it works and that its rewards and requirements are right. That's why every code you try on Roblox Den works.

  1. Checks every code in-game

    Renato tests every new Nightmare Defense code in-game, and re-checks any code that enough players report as not working.

  2. Keeps this page up to date

    When Nightmare Defense changes how codes are claimed, adds a new requirement or launches a new promotion, Renato makes sure it's covered here first.

  3. Lists exact rewards and requirements

    Every code shows exactly what it gives and any level or gamepass it needs, so you know what you're getting before you redeem it.

Renato isn't the only Code Guardian around here: Erwin and Nicole check new codes for this game whenever Renato is away or asleep.

About Nightmare Defense

In Nightmare Defense, you'll be tasked with utilising a selection of evil minions to defend your base against oncoming hordes of enemies. With a range of different minions to choose from, including mummies, yetis, and even Slenderman, you'll be sure to find one that suits your defense strategy the best. With every wave successfully defeated, you'll earn coins to spend on upgrading and purchasing new minions.

If you're looking to show off your defense skills, or are tired of defending solo, be sure to try out the multiplayer mode - here you'll get to team up with other players to defend against enemies with!
