Quarantine Zone: The Last Check Walkthrough & Cheats（Latest update）

Updated for 2026 | Verified Working

Let’s be real: Quarantine Zone: The Last Check is unforgiving. One moment you’re carefully managing your inventory, feeling like a tactical genius, and the next, a horde corners you in a dead-end hallway with zero ammo and a broken flashlight. Honestly, I got stuck in the subway section for three hours—dying to the same stalker enemy repeatedly—before I finally looked for a way to even the odds.
Whether you’re here to bypass a frustrating difficulty spike, test out weapon mechanics without wasting
resources, or just want to explore the lore without the constant stress of permadeath, using a trainer can
completely change your experience.

How to Use Quarantine Zone: The Last Check Cheats

Getting cheats running in this survival horror title is straightforward, but you need to follow the right order of operations. The game uses a custom game engine that can be finicky with memory injection, so following these steps is crucial to prevent the game’s anti-tamper code from crashing your session.

Installing the Quarantine Zone: The Last Check Trainer

Most trainers come as standalone executables or injected DLLs. For the standalone version, you’ll want to ensure your antivirus doesn’t flag the file—a common false positive for any software that modifies memory addresses. This happens because trainers work similarly to debugging tools, hooking into the game process to alter values like health or ammo counts.

1. Download the trainer files to a dedicated folder, preferably not on your desktop to avoid permission issues.
2. Right-click the executable and select “Run as Administrator.” This gives the tool the necessary privileges to read the game’s memory.
3. Locate your game installation path if the trainer doesn’t find it automatically. It usually looks like this:

C:\\Program Files (x86)\\Steam\\steamapps\\common\\Quarantine Zone

Once the trainer is open, launch the game. You should hear a confirmation sound or see a “Trainer Activated” notification in the overlay. If you don’t hear the beep, alt-tab out and check if the trainer process is still running.

Handling Antivirus False Positives

It is extremely common for Windows Defender or third-party antivirus software to block cheat tools. This isn’t because the file is malicious, but because the behavior of “injecting code into another running process” looks suspicious to security algorithms. To fix this, create a folder named “Cheats” in your Documents, add that specific folder to your Antivirus Exclusion list, and extract the trainer there. This prevents the software from silently
deleting the .exe file every time you try to run it.

Activating God Mode and Infinite Ammo

Once you are in-game and have loaded your save, test the hotkeys. For most trainers, F1 triggers God Mode, rendering you immune to zombie bites, environmental damage, and fall damage. F2 usually toggles Infinite Ammo.

I recommend toggling these on after the level fully loads. Activating them in the main menu can sometimes cause the UI to glitch out, showing you have 999 ammo but preventing you from reloading or interacting with
objects. If the cheats don’t seem to work immediately, try firing one bullet or taking a small amount of damage
to force the game to update its memory values.

Using Quarantine Zone: The Last Check PC Mods Safely

Modding affects game files directly. Before installing any visual mods or gameplay overhauls, navigate to your save directory:

%LOCALAPPDATA%\\QuarantineZone\\Saved\\SaveGames\\

Copy the contents of this folder to a safe location. If a mod corrupts your progress, you can simply paste these files
back to restore your checkpoint. This is especially important in Quarantine Zone, as the game uses a
strict autosave system that might overwrite your good save with a corrupted state the moment you exit a menu.

Enhance Your Survival with XMODHUB

If you don’t want to mess with sketchy file downloads or worry about version mismatches every time the game patches, XMODHUB offers a streamlined, all-in-one solution. It’s designed for gamers who want the benefits of modding without the technical headache.

Why Choose XMODHUB for Quarantine Zone: The Last Check?

XMODHUB detects your game version automatically and loads the correct cheat table. This eliminates the “trial and error” of finding a working trainer for the specific build you are playing. Plus, it’s malware-free and updates automatically, ensuring you’re always ready for the next patch.

These featured mods are just the beginning. Whether you’re looking to skip tedious grinding, experiment with different playstyles, or speed up your progression, XMOD’s comprehensive toolkit offers dozens more options tailored to your playstyle.

Exclusive Features for Survival Horror Gameplay

Beyond the basics, XMOD provides tools specifically designed for the survival horror genre. You can manipulate flashlight battery life, so you’re never left in the dark, or adjust player speed to outrun faster enemies in the late game. One of the most underrated features is the “No Infection Buildup” toggle, which completely negates the game’s most stressful timer mechanic.

Quarantine Zone: The Last Check Walkthrough Tips

If you prefer to play legitimately or just need strategy advice to complement your cheats, understanding the core
mechanics is vital. The game doesn’t hold your hand, and even with infinite ammo, getting lost or cornered can
lead to a game over.

Managing Resources in Quarantine Zone: The Last Check

Inventory space is your biggest enemy. Prioritize medical supplies over extra ammo for weapons you rarely use. A good rule of thumb: if you haven’t fired the shotgun in the last two chapters, you probably don’t need three stacks of
shells. Combine herbs immediately to save slots. Also, don’t hoard crafting components; use them to upgrade your
melee weapon durability as soon as you find a workbench. A broken pipe won’t save you when a Clicker-variant is sprinting at you.

Weapon Tier List for Survival

Not all weapons are created equal. Knowing which guns to upgrade can save you hours of frustration.

• S-Tier: Pump Action Shotgun. Found in the Police Station locker. This is your “get out of jail free” card. It staggers almost every enemy type, including the armored SWAT zombies. Prioritize upgrading its reload speed first.
• A-Tier: Crossbow. Silent and deadly. The bolts are retrievable, making it the most ammo-efficient weapon in the game. Use this for clearing isolated enemies without alerting the horde.
• B-Tier: Silenced Pistol. Good for headshots on weak infected, but lacks stopping power against bosses. Only upgrade the magazine capacity if you have spare parts.
• C-Tier: Assault Rifle. It sounds fun, but the recoil is terrible and it eats ammo too fast. Save it for the final boss fight where DPS matters more than precision.

Crafting Priority Guide

You will never have enough alcohol and rags to craft everything. Here is the priority order you should follow:

1. Molotov Cocktails: Essential for crowd control. One well-placed Molotov can clear a room of 10+ infected, saving you dozens of bullets.
2. Medkits: Only craft these if you are in the red. The game often spawns health items before boss fights, so don’t overstock.
3. Silencers: These break after a few shots. Only craft one if you are entering a stealth section like the Library or the Hospital Ward.

Strategies for Surviving Difficulty Spikes

The sewer level is notorious for its sudden difficulty spike. When facing the “Stalker” enemy type, do not run in a straight line. Use the environment to break line of sight. These enemies flank you, so keep your back to a wall whenever possible. If you are using cheats, this is a great place to toggle “One-Hit Kill” just to get past the frustration and back to the story. Another tip for the Hospital boss: aim for the legs. It slows him down significantly, giving you time to reposition.

Stealth vs. Combat

While it’s tempting to blast everything with your infinite ammo cheat, the game rewards stealth. Noise attracts enemies from adjacent rooms, meaning a single gunshot can turn a manageable encounter into a swarm. Use bottles and bricks to distract enemies. Even with God Mode, getting swarmed can physically block you in a corner, forcing a reload. Crouch-walking reduces your noise footprint by 80%, which is essential for the Library section where the blind enemies reside.

Practical Test: God Mode vs Normal Gameplay

We tested the game both with and without the XMOD trainer to see how it impacts the atmosphere and gameplay loop.

How God Mode Changes the Experience

Playing normally, Quarantine Zone is a tense, claustrophobic experience where every shadow is a threat. With God Mode active, the game shifts from horror to an action power fantasy. You lose the fear of death, which allows you to appreciate the level design and environmental storytelling that you usually miss while running for your life. You can stop to read the notes scattered around the world without worrying about a zombie gnawing on your neck. It turns the game into a dark walking simulator with shooting elements, which is actually quite relaxing.

For example, in the “Subway Tunnels” chapter, there is a section where you are chased by an invincible
behemoth. Normally, this is a panic-inducing sprint where you miss all the environmental details. With God Mode,
I was able to stop and look at the graffiti on the walls, which actually revealed backstory about the outbreak’s
origin that I had completely missed in my first three playthroughs. It transforms the game from a stress test
into an interactive movie.

When to Use Cheats in Quarantine Zone: The Last Check

I recommend playing the first few chapters vanilla to understand the intended pacing. Enable cheats if you hit a wall—like the Hospital boss fight—or if you are replaying the game to find collectibles. There is no shame in using a trainer to skip the grindy parts of a single-player game. If you have limited time to play after work, using “Super Speed” to backtrack through empty areas is a massive quality-of-life improvement.

Common Mistakes When Using Cheats

Even with the best tools, things can go wrong if you aren’t careful. Here are the most frequent mistakes players make when modding Quarantine Zone.

Leaving God Mode On During Scripted Deaths

Some sections of the game require your character to “die” or be captured to advance the plot. If you have God Mode enabled, the game script may hang indefinitely because your health never reaches zero. If you notice a cutscene isn’t triggering or an enemy is attacking you endlessly without effect, toggle off God Mode immediately.

Over-Reliance on Quest Item Cheats

Using a “Give All Items” cheat can be dangerous. It often populates your inventory with key items (like the Sewer Key or Blue Keycard) before you’ve triggered the quest to find them. This can break the game’s logic, leaving you stuck with a door that won’t open because the game thinks you haven’t “found” the key yet. Only spawn ammo and crafting materials, never key items.

Troubleshooting & Fixes

It’s annoying when you press the hotkey and nothing happens. Here are the most common fixes for when your trainer refuses to cooperate.

Troubleshooting Quarantine Zone: The Last Check Trainer Errors

First, check if your NumLock is on. Many trainers map keys to the Numpad. If that’s not it, ensure you have the correct version of the .NET Framework installed, as many cheat tools rely on it. Also, try disabling the “Steam Overlay” in the game properties, as it can sometimes conflict with injection methods. Running the game in “Windowed Borderless” mode instead of “Fullscreen” can also help the trainer hook into the visual overlay correctly.

Fixing Version Mismatches and Save Issues

If the game recently updated, your old trainer might crash the game. This is because the memory addresses for health and ammo have shifted. In this case, you need to wait for an updated trainer or use a platform like XMODHUB that handles these updates automatically. If your save file won’t load, verify the integrity of game files through your launcher (Steam > Properties > Installed Files > Verify Integrity).
