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 730,649 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 Undertale Arena code in-game, and re-checks any code that enough players report as not working.

  2. Keeps this page up to date

    When Undertale Arena 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.

Progressing and becoming stronger means you can buy items and other goodies from the shop to multiply your power, eventually becoming the best and most powerful fighter there is in the Undertale Arena.
