Quarantine Zone: Best Upgrades & Items

Quarantine Zone: Best Upgrades & Items

The fluorescent lights flickered as another wave of refugees pressed against the checkpoint. Each cough, each nervous tic, felt like a personal accusation. My job was to decide who lived and who was turned away to face the horrors outside, and every choice hinged on the razor’s edge of limited resources. The relentless management of your outpost in Quarantine Zone: The Last Check can feel overwhelming, but strategic upgrades can turn the tide.

You earn Research Points (RP) by completing various tasks within the game, and these points are your lifeline for improvement. Some upgrades enhance your personal tools, while others fortify your base defenses. Each offers unique benefits, but you can’t acquire them all in a single playthrough.

This guide will outline which upgrades I believe offer the most strategic advantage for your RP investment.

Fortifying Your Frontline: Base Upgrades in Quarantine Zone: The Last Check

I once managed a small retail store; every square foot had to justify its existence through sales. Similarly, your base is the hub of your entire operation in Quarantine Zone. It’s the haven where survivors arrive and where you determine their fate. Every five days, you have the opportunity to evacuate survivors, earning crucial cash and RP. Smart base upgrades are essential for maximizing these returns.

  • All Tent upgrades: More survivors mean more resources from each evacuation. Upgrading your tents increases your capacity, leading to a greater influx of RP and cash. These, in turn, streamline base management and accelerate further upgrades.
  • Ability Accelerator in Defense Center: Initially, drone defense can be engaging. However, as the days progress, the zombie hordes become increasingly relentless. The Ability Accelerator drastically reduces weapon reload times. This becomes increasingly critical as you get further in the game, where tougher undead require rapid-fire responses.

  • Generator 3 and Hydroponics: Resource efficiency translates to financial stability. Generator 3 enhances fuel efficiency and power output, ensuring your facilities remain operational. Hydroponics for your Canteen allows you to produce eight meals daily. This eliminates the need to purchase external supplies, saving considerable cash, especially when survivor numbers are low and the Canteen operates autonomously.

What’s the best way to manage resources early on?

Early gameplay is all about surviving, but you also want to be thinking about efficiency. Prioritize upgrades that reduce your reliance on external resources. Every saved credit is an investment in future growth.

Perfecting Your Instruments: Item Upgrades in Quarantine Zone: The Last Check

I’ve seen veteran doctors rely on outdated tools, believing experience alone was enough. Yet in Quarantine Zone, relying on default equipment is a quick path to failure. As you progress, you gain access to new diagnostic tools. These items enable you to identify infected individuals more accurately. Upgrading these tools significantly boosts their effectiveness, making your job easier (and saving lives).

  • Clear View for Scanner: Visual symptoms can be easily obscured by dirt or environmental factors. The Clear View upgrade ensures that your scanner ignores these contaminants, allowing for precise analysis.
  • Titanium Head for Hammer: The Hammer’s default effectiveness is questionable. The Titanium Head upgrade focuses its power, allowing you to target the head for maximum impact against the infected.
  • Autofocus for Matioscope: Manual focus adjustments consume valuable time. This upgrade automates the process, allowing for faster and more efficient diagnoses.

How important is speed in making the right choices?

Time is a luxury you can’t afford. The faster you can process each survivor, the more you can help. Speed upgrades and efficient base layouts are not just conveniences; they’re necessities.

Are item upgrades worth the Research Points?

Item upgrades are more than worth it if your aim is to increase the accuracy and speed of your diagnoses. Upgrading makes the difference between blindly guessing and confidently knowing.
