Guide to Xenobiology

Xenobiologists are in charge of the creation, care, and eventual culling and harvesting of slimes, which are dangerous to handle without the right equipment. Slimes yield slime plorts (also called extracts) when processed after death; injecting reagents into a plort triggers reactions. The in-game book Slime plorts and reactions lists all plort reactions and links to this guide.

Familiarize Yourself

You and your slimes are typically located in a remote area referred to as Xenobiology.

• The Lab: Located behind the main airlock. Contains multiple containment cells.
• Containment Cells: Each cell usually has a disposals chute to safely give food to slimes and a lockdown button to shutter the glass.
• Layout Tip: Use main cells when possible; isolation cells often lack the disposals/lockdown infrastructure.

Essential Tools

Item	Purpose	Pro-Tip
Xenofauna baton	Primary Culling Tool	Highly Recommended. The most reliable way to kill slimes. It stuns on the first hit and kills shortly after without damaging the body, ensuring maximum plort yield.
Core Stopper Gun	Ranged Culling	Superior Control. Rapidly "stops" slime biological activity at a distance. Much safer than a baton as it allows you to cull from outside the cell or across a room while keeping the corpse intact.
Fire extinguisher	Emergency Kill	Last Resort Only. While water is a "weakness," it is actually highly ineffective for professional culling. It deals damage slowly, creates slipping hazards, and often requires several refills to kill a single adult. Use only if a slime escape is imminent and your specialized tools are empty.
Syringe / Dropper	Reagent Injection	Used to trigger reactions in slime plorts.
Welder & Mask	Maintenance	Essential for mending cracks in cell windows.

Optional Gear

• Medibot: (Robotics) Provides healing if the lab is far from the Medical wing.
• Temperature gun: (R&D) The Cold setting can kill slimes at range. Like water, it is significantly slower than specialized Xenobiology gear and should be used cautiously to avoid damaging the environment.

Basics of Slime Care

Getting Started

You usually start with grey slime plorts. 1. Obtain Liquid Plasma (from the lab grinder). 2. Inject it into a Grey Plort to spawn a baby grey slime.

Why Proper Culling Matters

Using a Slime Baton or Core Stopper ensures the slime dies in a state that allows for easy harvesting. While the Fire Extinguisher is effective at stopping a rampaging slime, the "brute force" nature of high-pressure water makes it much harder to salvage high-quality extracts. Always aim to baton or shoot slimes before they grow out of control.

General Rules

• The Grey Line: Always keep one cell dedicated to grey slimes. They provide Monkey Cubes (Blood + Grey Plort).
• Isolation: Never put more than one color in a cell. Slimes of different colors fight, making management impossible.
• Steroids: Plorts usually have 1 use. Injecting a Slime Steroid Agent increases this to 3 uses.

Slime Plort Reactions

Standard reactions require 1u of reagent. Reactions with specific amounts are noted (e.g., 5u).

Colour	Plasma	Blood	Water	Other
Grey	Baby Grey Slime	3x Monkey Cubes	—	Blattedin → Roach Cubes; Pararein → Spiderlings
Green	Mutagen	—	Genetics Purger	—
Metal	Steel + Plasteel	—	Plastic (10 sheets)	Radium (5u) → Uranium
Gold	Gold Bars	—	—	Nutriment (5u) → Honey
Silver	Flash + Food	—	—	Nutriment (5u) → Enzyme; Uranium (5u) → Silver + Tritium
Blue	Glass + Plasma Glass	—	Frost Oil	—
Dark Blue	Delayed Cold Snap	—	—	Honey (5u) → Pure Slime Jelly
Orange	Mass Fire (Danger!)	Pepper Spray	Fire/Pressure Resist Jar	—
Yellow	Shock Resist Jar	EMP (Danger!)	Slime Lights	—
Purple	Slime Steroid Jar	—	—	Sugar → Slime Jelly
Dark Purple	Plasma Sheets	—	—	Au+Ag+U (1u) → Random Mod
Red	Glycerol	Enrage Slimes	Speed Jar	Frost Oil → Osmium/Metallic Hydrogen
Pink	—	—	—	Honey (5u) → Docility Jars
Black	—	—	—	Mutagen (1u) → Random Baby Slime
Oil	Explosion (Danger!)	—	Thermal Vision Mod	Space Lube (5u) → Non-slip Soles
Light Pink	—	—	—	Plasticide (5u) → Pistol; Wood Pulp (10u) → Bat
Adamantine	Golem Rune	—	—	Slime Jelly (1u) → Diamonds + Biomatter; Au+Ag+U (1u) → Platinum

Slime Protection

Slimes can harm you in several ways. Match your gear to the slime:

• Bio Suits: Reduces damage from glomping and blocks chemical injections.
• Fire Suits: For Orange slimes or when Dark Purple slimes ignite plasma.
• Bomb Suits: Essential when handling Oil slimes.
• Radiation Suits: Required for Green slimes or uranium processing.

Slime Psychology

Discipline vs. Obedience

• Discipline: Using a baton on a slime makes it stop attacking.
• Obedience: Disciplining a slime while it is attacking someone (justified) increases obedience. High obedience makes discipline last longer.
• Resentment: Disciplining a slime for no reason (unjustified) builds resentment. Too much resentment leads to Rage.

Commands

If a slime is obedient or likes you, you can use voice commands:

• "Slimes follow"
• "Slimes stop"
• "Slimes attack [Target]"

Quick Reference

• Primary Goal: Reach Dark Purple (Plasma) and Grey (Food).
• Tools of Choice: Use the Slime Baton or Core Stopper for kills.
• Safety First: The extinguisher is for emergencies only.
• No Mixing: Keep colors separate to prevent Slime Wars.
