How to Get “Treacherous John Doe” Forsaken The Battle Bricks Tutorial

Forsaken and The Battle Bricks have been dropping plenty of creative and chaotic updates lately, and one that’s got players talking is the Treacherous John Doe skin. While it’s meant as a humorous reference with a bit of satire, there’s still a way to understand how to access the so-called “Tumor Mode” and what it means for unlocking this rare John Doe version. Here’s a breakdown of how it works and what you need to know.


What Is Treacherous John Doe?

The Treacherous John Doe is a themed skin tied to Tumor Mode — a tongue-in-cheek feature that’s part joke, part secret mechanic in Forsaken. It plays into the mysterious lore surrounding John Doe, a recurring figure in many Roblox myths. While the guide might seem chaotic, the core idea is to show players how to access the hidden mode where this skin becomes available once officially released.

How to Enter Tumor Mode

Currently, the Tumor Mode isn’t an official part of the main menu, but you can try accessing it by doing the following steps:

  1. Join the Game – Start Forsaken or The Battle Bricks as usual.
  2. Rejoin During Load – When the game is still loading, rejoin quickly or refresh your session.
  3. Spam the Cog Icon – While the game is loading, keep clicking or tapping on the cog icon (settings) repeatedly.
  4. Activate Tumor Mode – If done correctly, you’ll trigger a hidden effect that places you in Tumor Mode. This is more of a fun easter egg for now, but it sets the stage for future events or skins.

This sequence is mainly for entertainment, so don’t worry if it doesn’t always trigger — it’s part of the community joke surrounding Forsaken’s experimental updates.

How to Get Treacherous John Doe

Once Tumor Mode becomes officially active:

  1. Enter Star Extreme Mode – You’ll need to beat any Star Extreme level in Forsaken.
  2. Complete the Challenge – Survive and clear the mode entirely.
  3. Unlock the Skin – After clearing, you’ll receive the Treacherous John Doe as a reward.

Of course, the original tutorial jokingly says it costs “400,000 Robux” to complete — that’s not real. It’s a parody of how tough or grind-heavy these challenges can feel.


The Treacherous John Doe skin in Forsaken is a fun blend of myth, humor, and hidden mechanics. Whether you’re trying to trigger Tumor Mode for laughs or just exploring the game’s secrets, this guide gives you a quick way to test it out. Keep an eye on future updates — if Tumor Mode becomes official, John Doe’s chaotic energy might just find its permanent place in the Forsaken universe.
