Guide to xenobiology

From Yogstation-13
Jump to navigation Jump to search

Xenobiology is the breeding and harvesting of slimes and their extracts for scientific purposes. This all takes place in the xenobiology lab where you spawn, and is arguably more dangerous than making bombs if you don't know what you are doing. Which is a good reason to read this!

Home on the Range

BoxStation Xenobiology

As a Xenobiologist, you’re not going to get out much ever. You’re the most autonomous area on the entire station if you know what you're doing, and nobody ever bothers you (usually).

First, get familiar with your new home.

The workplace includes a couple of closets with bio-hazard suits, a monkey recycling machine, a slime processor, and an All-In-One Grinder with several sheets of plasma. Also included is a smartfridge modified to hold slime extracts within easy arm reach from the slime processor, a wrench which can unanchor all the machinery (so you can reorganize your workspace), a few containment units and a disposal unit that leads to space.

The lab also contains a slime containment area with pens, some of which start with a baby grey slime. There is also a special containment pen that's larger and more secure than the rest. This is ideal for containing and experimenting on other alien lifeforms should the station manage to capture/produce one. Usually though, it's just for storing extra slimes. You can read more about your workplace for each map by clicking here.

Slime comp.png Slime Console

The console is your main working tool when dealing with xenobiology. With it you can move slimes, kill them, feed them, and process dead monkeys with mere clicks of a button!

It's strongly advised grabbing the wrench (usually located next to the shield projectors) and moving the fridge and slime processor within close range of the console you're using as to cut out a lot of unnecessary movement.

Safety Advice

Before you start breeding the slimes, make sure you have a fire extinguisher in your backpack. You'll rarely meet a ravenous, hungry slime if you're using the console, but it still happens and having an extinguisher could very well be the difference between a dead slime and a dead you.

If you aren't using the console, then this goes doubly so as you'll be near a lot of slimes, usually before you cull their numbers, and while they're normally docile towards you whom are effectively their "God", they occasionally grow resentful for their species' exploitation and try to kill you for no particular reason. In that case, kill the blasphemers with a clear conscience, DEUS VULT!

Breeding slimes


If you are using the console, simply insert the monkey cubes from the boxes into the console. The console can now teleport monkeys directly inside the slime pens! If you are not using the console, then use the monkey cube on a water source and feed it to the slimes using the pen disposals units. Slimes need one monkey to become an adult and another to split.

  • You can send both monkeys at once into a baby slime's pen, so you don't have to think about it until they split.
  • Do NOT enter the pen and bash the monkey, the only thing that will happen is slime will get less food.

Once they're fed enough, after a while the adult slime will split into 4 baby slimes.


Time to kill your darlings. Decide which baby slimes you don't want to keep.

If you are using the console then proceed to warp them up. The console can hold up to 5 slimes at a time. Teleport them onto the kill pen; it's the one with the blue floor, connected to a freezer. The sharp cold will kill the slimes quickly: when they stop moving they're dead and you can pick them up for the next step.

If you are not using the console then get out your fire extinguisher and blast the slime to death. You should refill the extinguisher at a water tank after every use. You could also choose to drag the slime into the kill pen - just make sure you're wearing warm clothing!


Collect the dead slimes and drop them above, or next to, the slime processor. It will automatically suck in the slimes; when it's done, activate it to grind them. It will, after a while, drop a slime core of the respective color for each slime grinded.

  • Upgrading the grinder will make it go faster and give more cores per slime.
  • A Bio Bag from any biohazard locker can mass-collect slime cores and easily drop them into the fridge for easy access.


You can decide to sell some of your cores at the plort machine for research points. To do this, simply insert a core into the machine and your department will receive research points.

  • Rarer slime cores give you more research points.
  • Upgrading the grinder will give you more research points per core.

Friendship and Slimes

If you've been following the guide and diligently breeding and culling the slimes, you may have noticed that while the slimes very quickly attack and eat the monkeys you offer them, they have little to no interest in eating you. This is because you've become their "friend", a status that can be earned by simply being the one sending them monkeys. To check if slimes are friendly, say "Hello slimes"; all the slimes that consider you their friend will say hello.

There are some commands you can issue as a slime's friend, including "follow", "stop" and "attack". Keep in mind that these commands are exceedingly finicky, and are rarely used for a reason. Slimes will not attack other slimes or friends.

Defending against slimes

So either by you not feeding the slime enough, the slime being an dick, or reasons, a slime has tried to kill you. If the slime is a baby, this is annoying. If the slime is an adult, you may die if you don't know what you're doing.

Slimes have two attacks: A glomp that does brute damage with adults dealing more and a chance to stun, and the far more dangerous feeding attack which deals cellular damage and empowers the slime, a rare and very difficult to heal type of damage. If a slime starts feeding on you, wrestle it off with disarm intent and spray it down with an extinguisher (You DID get an extinguisher, right?) when you get it off until it dies. After that, hobble off to medbay for healing.

While this is generally more a tip for you when NOT playing Xenobiologist, in the event of a very rare slime outbreak, perhaps of sentient slimes, get an extinguisher and hide. A horde of angry slimes can multiply fast, and while slimes are normally unintelligent and docile, outbreaks of them are nearly always done on purpose by someone wanting to destroy the station, and are thus paired with usage of red extracts enraging slimes and light pink or black extracts making very deadly intelligent slimes. Pray that the AI is able to stop them, and that the xenobiologist who released the slimes doesn't follow up with something worse.

Slime Mutations

This flowchart shows the results of each slime's mutations when splitting, with options labeled "2x" having twice the chance of occurring.

There are a lot of different types of slime. You begin with two grey slimes but you can breed them to catch all the pokèmon! slimes! Each kind of slime has its own powers from its extract.

Every time a slime splits by being fed enough, it has a chance to mutate based on it's individual mutation chance, a stat discovered by taking a slime scanner from the fridge and using it on the slime. The mutation chance is usually around 5%, so you will have to rely on miners to fetch the rarer colors for you. Think carefully about what colors you want and which slimes to keep. If you're breeding greys for monkeys, you'll want less chance of mutations, and if you want to get adamantines you will want to increase it!

NOTE: You can increase a slime's chance of mutation by injecting it with slime mutation potions from red slimes and decrease it with slime stability potions from blue slimes.


All injections require one unit of reagent. Dropper is your friend. You can also dilute your plasma by, for example, filling a beaker with 40u of water and 10u of plasma; a syringe will collect exactly one unit of plasma this way (and the water doesn't react).

Luminescent effects are a result of the slime person mutation into a Luminescents absorbing said core.

Green Slime Slimegreen.png

  • Extract creates some slime mutation toxin when injected with plasma. Having at least 4u in your system will eventually turn you into a random jellyperson. They have several pros and cons, but what is important to xenobiology is that slimes will never attack you and your blood is no longer valid for blood-based reactions, as it is replaced by slime jelly. Ingesting more slime mutation toxin when you're already a jellyperson will turn you into another random subspecies.
  • Extract creates various other mutation toxins when injected with different chemicals as shown below
Chemical Injected Toxin Created Effect of toxin when injected into you
Radium Lizard mutation toxin Turns you into their respective race

  • Major: Temporarily pacifies creatures around the user, making them nonviolent for some time.

Gold Slime Slimegold.png

  • Extract spawns five random dangerous hostile mobs when injected with plasma.
  • Extract spawns three random dangerous mobs when injected with blood. These mobs are not immediately hostile, but may be provoked by certain actions, proximity to other creatures (such as your slimes) or if they encounter a construct or mech.
  • Extract spawns one random friendly critter when injected with water. Now you can fill xenobiology with mobs even if you're a giant pussy!

See here for the list of summonable mobs.

  • Major: Turns the user into a shadowperson.

Light Pink Slime Slimelightpink.png

  • Extract creates a bottle of sentience potion when injected with plasma, a potent chemical mix that will bring human level intelligence to any animal, slime, monster or generally active thing you feed it to. Make Ian sentient! Create an army of gold slime minions! The possibilities are limited only by your own deviousness and the number of ghosts in the round.
  • Extract will spawn a simple mob renaming potion when injected with water.
Luminescent Effects
  • Minor: Spawns a slime docility potion.
  • Major: Spawns a sentience potion.

Adamantine Slime Slimeadamantine.png

Golem shells can then be finished with ten sheets of any material, which will affect the golem's properties. After completion, a ghost can possess the shell to spawn as a golem. It will follow the orders of who finishes the shell above anything else, and inherit conversion antagonist status, such as cult, from their owner.
Luminescent Effects
  • Minor: Temporarily increases the user's armor, reducing overall damage taken.
  • Major: Turns the user into an adamantine golem.

Special Slimes

Rainbow Slime Rainbow slime.gif

To attain this rare slime you must breed a slime with a 100% mutation chance!

  • Extract will spawn a random slime when injected with less than five units of plasma.
  • Extract will explode into randomly-colored slime cores when injected with at least five units of plasma.
  • Extract will explode into randomly-colored slime cores with water, plasma, and blood in them when injected with slime jelly. This will trigger their reactions unpredictably and chaotically, and almost certainly cause mayhem wherever it happens.
  • Extract will generate a mind transference potion when injected with blood. You can use it to transfer your mind into a creature. This is not reversible and will result in your old body's instant death.
  • Extract will spawn a flight potion when injected with 5u of Holy water and 5u Uranium.
Luminescent Effects
  • Minor: Changes the user's color randomly.
  • Major: Spawns a random slime core.


The powerful crossbreeding that gifts you with godlike power! You need an adult slime which is the "base" and 10 slime cores of the same type, which are the "effect".

For example, you have an adult green slime and you add 10 yellow cores. That makes a Green Charged Core which can be activated in hand and mutates you to a slime person, letting you choose which strain to turn into. Also these special slimes are normal sized items. They fit in backpacks.

Base Slime Description
Slimegrey.png Grey Slowly feeds all slimes in the area. Effect is blocked by walls.
Slimeorange.png Orange Ignites anyone in range of the crystal and heats the surrounding air to 500K. Effect is blocked by walls.

Rainbow slime.gif Rainbow Does nothing on its own but will accept crystalized extracts to begin emitting the same effect as the consumed extract, allowing for multiple different effects in the same space.

So You're a Traitor

What you can get here that can't be gotten easier elsewhere is an EMP and random hostile animals which include a few very deadly ones CARPS SPACE BEARS ALIUMS SPIDERS HIVEBOTS PINE TREES OH GOD IT'S HORRIFYING. Releasing the slimes is somewhat viable, but you will likely get caught doing so, and baby slimes are rather tame (Unless you have Red Slime Essence. Then it's a party.)

On the plus side, you do have a disposal chute that goes directly to space. Pretty handy for disposing of evidence, or people.

Also remember the havoc with grenades and bombs you can cause! If you can get access to chemistry as well you can make some interesting grenades. Advanced mutation toxin with sugar in one beaker, phosphorus and potassium in the other. Set a timer in the Medbay and drop it and listen to all the people turning into Slimes. This is when you laugh to yourself and realize it backfires when all the slimes attack you.

A full guide to ruining someone's day with slimes:

  • Red - Makes all slimes within sight range hyper aggressive. Also creates potions that can increase a simplemob's speed when injected with blood, useful for enhancing your gold slime army.
  • Green - Produces 1 unit of a chemical that turns people into different races including slime persons. Use it on someone and convince the AI that they're a danger to humanity. Needs at least 5 units for it to work in a smoke grenade.
  • Black - Turns people into actual grey slimes, no fort save. Again, 5 units in a smoke or foam grenade will make for a very interesting shuttle flight.
  • Orange - Ignites a large fire.
  • Yellow - Huge EMP.
  • Silver - Only way to get real roburgers (with nanites).
  • Gold - We all know what this does.
  • Sepia - Stops time in a small radius, allowing you to wreak many kinds of havoc.
  • Oil - Fiery Explosion. One of the fastest ways to mass produce a large array of explosions, even if they mostly cause fire. Also makes glycerol with blood in case you want to make a stupidly large hole in the station with a bluespace beaker grenade
  • Adamantium - Makes golems that can be converted to the cult/soul shard/revved. They have to follow orders given to them by their creator so feel free to make them suicide bomb with gold slime cores.
  • Light pink - Enables you to make sentient beings, including anything a gold slime extract can produce. Magicarps included.
