Defense Island Code Guardian

Nicole Lucero

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 730,661 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

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

  2. Keeps this page up to date

    When Defense Island changes how codes are claimed, adds a new requirement or launches a new promotion, Nicole 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.

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

About Defense Island

In Defense Island, you'll be in charge of defending your very own island against oncoming hordes of enemies! To get started on preparing your defenses, you'll need to head to your inventory to see your available structures. Starting off with just three cannons, you'll need to strategically place them to ensure your island stays secure, and to also prevent any enemies from entering your safe zone.

When you've successfully defended against your first wave, you'll be rewarded with XP and coins to spend on new items. Continue to upgrade your defenses, unlock new and exciting contraptions to use, and see how many waves you can defend against in Defense Island!
