Lab Minigame Guide

Master organ extraction to discover new symptoms and expand your diagnosis toolkit

Last Updated: January 19, 2026

What is the Lab?

The Lab is an essential facility where you can discover new symptoms not yet in your symptom list. When you encounter a survivor with an unknown symptom, you can send them to the Lab for organ extraction and analysis.

Unlocks Day 4-5

The Lab becomes available when you first encounter an unknown symptom

One-Way Trip

Sending someone to the Lab is irreversible - the survivor dies during extraction

One at a Time

The Lab can hold only one person. Wait for 'Ready' status before starting

Tutorial First Time

The game highlights and guides you through the first unknown symptom

When to Use the Lab

You should use the Lab when you encounter symptoms that aren't in your symptom list:

Unusual Appearance

Something looks 'off' that you've never seen before

Unknown Visual Sign

A visible symptom that doesn't match anything in your list

Tool Shows ???

When a diagnostic tool detects something unrecognized

Tip

After Day 5, you won't get notifications for new symptoms - you must find them yourself!

Controls

Master these controls to efficiently complete the organ extraction minigame:

Color Coding System

Understanding the organ colors is crucial for successful extraction:

Green - Target

HOLD E to Extract

This is the organ you need to remove. It's also displayed on the right side of the screen for reference.

Don't destroy it with laser - you won't discover the symptom!

Yellow/Orange - Destroyable

HOLD LMB to Destroy

These organs block the path to your target. Safely destroy them with the laser to clear the way.

No penalty for destroying these

Red - Protected

DO NOT TOUCH

These organs must be avoided at all costs. Destroying a red organ counts as a mistake.

2 mistakes = experiment fails

Tips & Common Mistakes

Pro Tips

  • You don't need to select 'Unknown Symptom' in the list - it's discovered automatically
  • The green organ is randomly selected - no correlation with the actual symptom
  • Use RMB zoom for precision when the target is small or blocked
  • If you accidentally destroyed the green organ, just remove any other organ to exit

Common Mistakes to Avoid

  • Pressing ESC to Exit

    Organ won't count - wasted survivor

  • Destroying Green Organ

    No symptom discovered (but not counted as mistake)

  • Not Waiting for Ready

    Can't start minigame until person arrives

  • Hitting Red Organs

    2 mistakes = failed experiment
