Boss Fighting Simulator 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 731,004 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 Boss Fighting Simulator code in-game, and re-checks any code that enough players report as not working.

  2. Keeps this page up to date

    When Boss Fighting Simulator 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 Boss Fighting Simulator

Become the hero of the local village in Boss Fighting Simulator, a game where you'll be able to take down powerful bosses and earn coins as you do so. Before taking down your first boss however, you'll need to build up your character's strength points. This can be done through using the starter sword found within your inventory. Once you've gained enough strength, you'll then be able to take down your first boss, whether it be alone or with the help of other players.

With the coins earned from your victory, you'll be able to purchase new swords, boosts, and also upgrade your character's abilities. If you're looking for more of a challenge, be sure to head over to the PvP arena, where you'll be able to take on other players to earn bonus coins for your character!
