Mastering the examination reactor 4 zone is not just about survival; it is the key to unlocking unique badges and acquiring top-tier loot that can tip the scales during your run. In this guide, we will break down the essential strategies, new pathing, and the best loadouts to conquer this revamped location effectively.
Understanding the Reactor 4 Revamp
A player walkthrough collected on 25 September 2026 shows the reworked Reactor 4 entrance beside the Sector 2 entrance, replacing the old western approach. Use that landmark, follow the generator objective, then the basement valve. This is a dated player route, not a freshly replayed room-by-room map; check the signs and active objective if the layout differs.
The player walkthrough collected on 25 September shows stationary “meat men” that grab the player and trigger a QTE. Watch the on-screen prompt and react quickly if grabbed. This observation comes from that dated video, not the Roblox game description.

Essential Badges and How to Earn Them
The examination reactor 4 area is currently a hotbed for badge collectors. The revamp introduced several new challenges that require specific items and teamwork. Here is how you can secure the most sought-after badges.
Badge

THE_GRUNT
One Antonio quest
ESPRIT_DE_CORPS
Five Antonio quests

Encounter and neutralise the hidden target; official description does not publish the room
TRIP_HAZARD
Fall into a tight space near a catwalk inside Reactor 4
A player badge walkthrough collected on 25 September shows taking an SHC23 from Antonio to Reactor 4, shooting the webbing and waiting for each layer to disappear before entering and attacking the mutant. This is a dated observed route. The author was uncertain whether everyone merely standing in the room receives credit: participation in the kill is safer advice than promising automatic shared credit.
Navigating the Basement: Survival Tips
The basement of the examination reactor 4 is notorious for being the most radioactive zone in the game. While you won't face standard hostiles here, the environmental hazard—the Elephant’s Foot—is deadly.
How to Handle the Elephant's Foot
Avoid Line of Sight: Never look directly at the Elephant's Foot. Direct exposure will lead to immediate death.
Valve Operation: You must reach the basement valve to progress the story. Perform this quickly to minimize radiation exposure time.
Gear Management: Ensure you have enough health consumables before descending. If you are injured, the lingering radiation will drain you faster than in other sectors.
Don't Look!
Community players have emphasized that the "DO-NOT-LOOK" signage is not flavor text. Looking at the object—even with night vision enabled—is a guaranteed way to lose your current life.
Combat Tactics for Sector 3 and Beyond
SOLE_PRACTITIONER is optional and does not advance rank. Capture the Sector 3 RIF Medical Tents solo, in one life, in a private server, with any class. Its current official reward is 25% extra NVG battery.
Tactics Against Hostiles
Axe Utility: Always grab an axe if available. Executions grant a 20 HP bonus, which is vital for long-haul survival.
The Bash Maneuver: When facing uninfected or basic infected, hit your bash key twice. This pushes the target back, providing you with essential breathing room.
Reloading: You can reload your weapon while performing an execution animation or wiping your mask. Master this multitasking to keep your DPS consistent.

Approach
Gilbert
Use cover and time shots
Dave
Keep range and a clear retreat; do not rely on shelf clipping
RIF
Clear the door before interacting with the desk
Optimization and Resource Gathering
Efficiency is the name of the game in Examination. If you want to optimize your time in the examination reactor 4 zone, always stop by Antonio in the spawn room first. His quests provide powerful weapons that make clearing subsequent areas, such as the logistics facility or Sector 2, significantly easier.
Furthermore, if you find yourself struggling with movement speed, remember that the new tutorial (accessed via the settings "Boot Camp" button) grants a permanent 10% stamina boost. This is a game-changer for players attempting the "Into the Fray" badge.
