This page covers the Reactor 4 rework documented in player material collected on 25 September 2026. It is not a complete changelog through today. Roblox’s official API records a game update on 12 October, but that timestamp alone does not reveal what changed; those later patch details are not covered here.
This update is not just a collection of minor tweaks; it fundamentally alters how you navigate the facility and engage with high-threat environments. By mastering these changes, you will not only increase your survival rate but also unlock powerful new tools to dominate the irradiated zones. Let’s break down everything you need to know about this massive overhaul.
Understanding the Reactor 4 Rework
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.

Generator + Basement Valve
The introduction of stationary "Meat Men" variants is a major hurdle. If you wander too close, these enemies will trap you. However, the developers have implemented a Quick Time Event (QTE) system that allows you to escape their grasp and neutralize them if you are fast enough.
Reactor 4 Survival Strategy
Always keep your stamina bar in check before entering the new Reactor 4 zone. The stationary enemies are ambush predators; walk slowly and keep your flashlight focused on corners to spot them before they spot you.
New Combat Mechanics and Enemy Balancing
Combat in Examination has become more nuanced. The Examination new update introduces several balance adjustments that affect both your offensive capabilities and the behavior of the infected.
Enemy Behavior Updates
Infected Enforcers: These units now possess a "counter bash" ability. If you mindlessly spam melee attacks, you will likely find yourself stunned and vulnerable.
Gilbert: This formidable enemy is now completely immune to backstab damage, forcing players to rely on frontal tactical engagement.
Vorax Spawning: Vorax units can now spawn in Sector 1, with a cap of three active at any given time. This increases the early-game tension significantly.
Weapon and Character Progression
Antonio has finally arrived at the spawn room. His questline is designed to be accessible yet rewarding. Completing his tasks is currently the most efficient way to obtain high-tier weaponry, which is essential for the "Overequipped" badge.

Mastering the Tutorial and Stamina Boost
For newcomers, the Examination new update finally adds a comprehensive tutorial. This is not just for show; completing the tutorial provides a permanent 10% stamina boost. In a game where movement speed and repositioning are life-saving skills, this 10% increase is a massive meta-shift.
Why the Stamina Boost Matters
In Examination, your stamina dictates your ability to sprint away from overwhelming hordes or reach extraction points before the radiation levels become lethal. By securing this boost early, you effectively increase your "error margin." If you make a mistake and get cornered, that extra stamina might be exactly what you need to break the line of sight and heal.
Advanced Strategies for the Basement
Once you successfully power the generator in the new Reactor 4, your next destination is the basement. This area is home to the "Elephant's Foot" and the critical valve required to progress the mission.
The walkthrough shows the generator followed by the basement valve. Follow the active objective and hazard warnings rather than extrapolating the old west-side map into the reworked rooms.
Community Insights and Meta Changes
The community has been buzzing about the "Russian Tank" flushy, which has become an instant fan favorite. While it seems like a cosmetic addition, the Examination new update also included dozens of under-the-hood bug fixes that have stabilized the frame rate for lower-end devices.
Frequently Asked Questions (FAQ)
Q: Where can I find the new Reactor 4 in the latest Examination new update?
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.
Q: How do I get the 10% permanent stamina boost?
A: You must complete the newly added tutorial located in the starting area. The boost is granted automatically upon completion of the basic training module.
Q: Are the new Antonio quests worth doing?
A: Yes. Antonio’s questline is the most reliable way to obtain high-tier weapons, which significantly helps in earning the "Overequipped" badge and clearing higher-difficulty zones.
Q: Is Gilbert still vulnerable to stealth attacks?
A: No. Following this update, Gilbert is immune to backstab damage. You must now use direct combat tactics to defeat him.
Remember, the facility is constantly evolving. Staying updated with the Examination Wiki is a great way to track future changes, but nothing replaces the experience gained from actually stepping into the irradiated halls of Menlo. Good luck, soldier—you’re going to need it.
