Creepjoiner

Creepjoiners are an exclusive event for the Anomaly DLC. You can encounter creepjoiners even if you have not yet activated the monolith.

Summary

A random pawn appears that wants to join your colony. The pawn waits on the edge of your map for someone to be sent to talk to them. They usually have some great benefit, but come with large risks too.

If rejected, they can either depart peacefully or become hostile.

Joiners have a specific list of upsides and possible downsides. Not all combinations below are possible. For some options there is a minimum raid point requirement (e.g. metalhorror or fleshbeast emergence), and some types will be limited in their downsides and benefits (e.g., blind healer will always have unnatural healing, or someone with joybringer cannot have disturbing).

Creepjoiners can be studied for if taken prisoner, as can some of their side effects such as entities. Creepjoiners are studied for Advanced Anomaly Research and give 2 Advanced Research with a cooldown of 2 days. The Creep joiner must be walking to be possible to be studied.

The monolith does not need to be active for creepjoiners to appear.

• Leathery stranger

Drawbacks

They can come with multiple downsides as well, which occurs after a 3-30 day delay while living with your colony:

• Nothing
• Desertion — The colonist will suddenly depart. Capturing and re-recruiting may only delay the desertion again.
• Traitor — The colonist will suddenly become hostile, accompanied by a message about their evil expression.
• Metalhorror — The colonist is infected with a metalhorror (requires level 2 Monolith).
• Crumbling mind — The colonist will experience a severe health effect that destroys their brain in a number of days. The crumbling can be healed with a healer mech serum or by having another joiner use Unnatural Healing.
• Entity jailbreaker — The colonist will suddenly attempt to free all of your contained entities.
• Psychic agony — The colonist emits a psychic pulse, on average once every 30 days, inflicting a large amount of psychic pain on nearby pawns. The pain is often enough to down your other colonists temporarily, and then lingers for multiple days at lower levels. Psychic sensitivity applies to this effect.
• Organ decay — The colonist will suddenly develop severe organ decay, requiring you to replace their heart, liver, kidneys, and lungs.
• Disturbing — The colonist upsets other colonists, giving them a −2 [name] rambling moodlet when interacting with them, which can stack up to −12 mood.

Separate from the downsides listed above, Creep joiners will become hostile if they receive friendly fire damage. This aggressive state on friendly fire damage can only occur once. If a Creep Joiner receives friendly fire, becomes captured, and then joins the colony, they will not respond to friendly fire with aggression.

If they become aggressive, they can react in various ways:

• Basic assault
• Fleshbeast emergence — A fleshbeast emerges from the joiner, killing them in the process.
• Sightstealer attack — The joiner will scream and summon sightstealers.

Also they are not able to romance ordinary pawns, but they can romance another creepjoiner, or form relationships to pawns with the psychic bond gene (such as Highmates). ^[verify].

Creep joiners initially start as Unwaveringly Loyal. If they are allowed to join your colony, the Unwaveringly Loyal aspect is removed permanently.

Analysis

Creepjoiners often have many powerful, colony-changing abilities. Evaluate the possible tradeoffs above, and be prepared to deal with sudden turncoat behavior. Inspect the pawn's entire bio and health tab carefully before recruiting them.

Performing a medical inspection surgery right after recruiting a creepjoiner can sometimes reveal their downside early.

Creepjoiners with crumbling minds or organ decay can be paused until you're able to deal with the issue by placing the colonist inside a cryptosleep casket.
