What Exactly is Treacherous John Doe?
Before we jump into the unlock process, let’s understand what makes this skin so special. Treacherous John Doe isn’t just another reskin – it’s a complete thematic transformation that ties into the fascinating lore of Tumor Mode in Forsaken.
The Lore Behind the Legend
Treacherous John Doe represents a corrupted version of the classic John Doe character, drawing inspiration from Roblox’s infamous urban legends. In Forsaken’s universe, this skin is connected to the experimental Tumor Mode – a hidden game mode that takes the base game’s difficulty and cranks it up to eleven with satirical humor and meme-worthy challenges.
Visual Design
When you unlock Treacherous John Doe, you’re getting:
A lab coat replacing John Doe’s standard attire
A corrupted left arm transformed into a menacing syringe
Specialized goggles covering the eyes
Extensive corruption effects covering significant portions of the character model
Unique animations and visual effects that set it apart from standard skins
This skin isn’t just about looking cool (though it definitely does) – it’s about being part of an exclusive club of players who have conquered one of Forsaken’s toughest challenges.
Understanding Tumor Mode: The Key to Unlocking
Here’s where things get interesting. Tumor Mode is the gateway to unlocking Treacherous John Doe, but it’s not your typical game mode. Let me break down everything you need to know about this mysterious feature.
What is Tumor Mode?
Tumor Mode is Forsaken’s hardest difficulty setting, featuring:
Enemy Transformations: All enemies shift into their alternate, more powerful forms
Increased Difficulty: Stage magnification values are doubled
Health Boosts: Enemy base HP increased by 100%
Enhanced Challenges: Demands tighter summon cycles and stronger unit investment
Star Tiers: Features 1-3 star difficulty levels within the mode
The Easter Egg Method (Community Discovery)
Before Tumor Mode was officially recognized, the community discovered a clever way to access it through an easter egg. Here’s how players originally triggered it:
Launch Forsaken on Roblox
As the game loads, perform a quick rejoin or refresh
Once in-game, rapidly and repeatedly press the Settings icon (gear button)
If successful, hidden visual effects or changes associated with Tumor Mode would appear
Important Note: This method is considered experimental and isn’t guaranteed to work consistently. It’s more of a community inside joke and fun exploration rather than a reliable unlock method.
Official Tumor Mode Activation
The legitimate way to access Tumor Mode is much more straightforward:
From the Battle Bricks title screen, click or tap the tumor logo repeatedly
This reveals and enables the TUMORE mode toggle
Once unlocked, you can switch between Casual, Normal, and Tumore difficulties
Tumore is recommended only after building a strong roster and mastering Normal mode
Step-by-Step Unlock Guide: Your Path to Treacherous John Doe
Alright, let’s get to the meat of this guide. Here’s exactly how you’ll unlock Treacherous John Doe, broken down into manageable steps.
Prerequisites: What You Need Before Starting
Before attempting the unlock, make sure you have:
Strong Unit Roster: Well-leveled units from Normal mode clears
Chapter Progress: Completed Chapter 1 and 2 on Normal mode
Game Knowledge: Understanding of basic mechanics and strategies
Time Commitment: 10-20+ hours for dedicated gameplay
Patience: This is challenging content that may require multiple attempts
Phase 1: Foundation Building
Step 1: Master Normal Mode
Complete Chapter 1 on 3 stars in Normal mode
This stabilizes your EXP gain and unlocks additional units
The extra unit from Chapter 1 completion is crucial for Tumor Mode success
Step 2: Expand Your Roster
Aim for Chapter 2 three-star completion in Normal mode
The Chapter 2 badge unit’s alternate form is extremely helpful for Chapter 3 Tumor fights
Focus on leveling units based on utility, not just ease of use
Prioritize Sword over Battler and Trowel for reliable early DPS
Step 3: Build Strategic Depth
Develop a balanced team composition
Include meatshield units for stalling
Add mid-cost DPS anchors for consistent damage
Prepare late-game boss shredders for tough encounters
Phase 2: Tumor Mode Activation
Step 4: Unlock Tumor Mode
Navigate to the Battle Bricks title screen
Click or tap the tumor logo repeatedly until the mode toggle appears
This is the standard access method for newcomers to the Forsaken collab
Step 5: Understand Tumor Mode Mechanics
Expect health and damage spikes from doubled magnifications
Stack a front row of cheap meatshields
Include one or two mid-cost DPS anchors
Prepare a late-game boss shredder for extreme encounters
Phase 3: The Grind – Completing Requirements
Step 6: Check Your Collab Tracker This is crucial because requirements can vary:
Option A: Complete Chapter 4 Utopia badge only
Option B: Complete Chapter 3 Tumore (≥1 star) PLUS Chapter 4 Normal (≥1 star)
Always verify your specific requirements in the in-game collab tracker rather than relying on external guides.
Step 7: Tackle Chapter 3 Tumor Mode
This is often the bottleneck for many players
Treat 1-star completion as your primary milestone
Use consistent meatshield uptime to prevent alt-form elites from breaking through
Focus on keeping your carries alive while they scale damage
Step 8: Conquer Chapter 4
If your tracker requires Chapter 4 completion:
Complete Chapter 4 on Normal mode (≥1 star)
OR complete the Chapter 4 Utopia badge if that’s your specific requirement
Use the strategies and units you’ve developed in previous chapters
Phase 4: Claim Your Reward
Step 9: Verify Completion
Double-check that all required badges and stars are earned
Ensure your collab progress is properly tracked
Confirm that all prerequisites are met
Step 10: Redeem Treacherous John Doe
Once all requirements are complete, the skin should automatically unlock
Check your inventory or skins menu
If it doesn’t appear immediately, try relogging or checking for pending rewards
Advanced Strategies for Tumor Mode Success
Let me share some pro-level strategies that will significantly increase your chances of success. These are the techniques that separate the casual players from the elite few who actually unlock Treacherous John Doe.
Core Teambuilding Principles
Unit Prioritization
Utility First: Always prioritize units based on their utility value, not just how easy they are to use
Sword Mastery: Among starter units, Sword outperforms Battler and Trowel for reliable early DPS and lane control
Meatshield Strategy: From Chapter 2 onward, meatshielding becomes extremely effective – keep cheap summonables on constant cycle
Leveling Strategy
Don’t Rush: Avoid the temptation to jump into Tumor Mode before finishing Normal 3-stars for Chapters 1 and 2
EXP Farming: The extra EXP and stabilizing unit from Normal mode clears will make Tumor Mode significantly easier
Progressive Enhancement: Level units gradually rather than trying to max out one unit immediately
Tumor Mode Loadout Optimization
Front Line Composition
Stack 3-4 cheap meatshields in your front row
This creates a sustainable barrier while your DPS units scale
Examples: Basic battlers, cheap summonables, low-cost units
Mid-Game DPS
Include 1-2 mid-cost DPS anchors
These provide consistent damage output
Look for units with good area damage or single-target focus depending on the stage
Late-Game Specialists
Prepare boss-shredding units for extreme encounters
On high-risk bosses (like C1-30 Deathbringer), consider specialized carries
Treat two-star and three-star Tumore as separate routing problems
Chapter-Specific Routing Tips
Chapter 1 Tumor Mode
Can be blitzed if your Normal mode roster is strong
Focus on consistent meatshield uptime
Prevent alt-form elites from breaking through your defenses
Keep your carries alive while they ramp up damage
Chapter 2 Tumor Mode
This chapter will punish low levels and weak cycling
Use your best stalling units
Consider pausing star attempts until you can farm more EXP from Normal clears
This is often where players hit their first significant difficulty wall
Chapter 3 Tumor Mode
The most common collab bottleneck
Treat 1-star completion as your primary milestone for Forsaken requirements
Requires precise timing and unit management
Expect to spend the most time on this chapter
Practical Difficulty Management
If You Can’t Find Tumor Mode
Repeat-click the tumor logo at launch until the mode toggle appears
This is frequently cited by new collab participants
Sometimes requires multiple attempts or specific timing
If You’re Failing Star Thresholds
Shift back to Normal mode to farm EXP and unlocks
Re-route Tumor Mode with tightened summon cycles
Increase your unit levels before attempting again
Consider adjusting your team composition
