To arrest your own colonist in RimWorld, select a drafted pawn, right-click the target colonist, and select "Arrest [Name]." The arrester will attempt to lead the colonist to a designated prison bed. This mechanic is primarily used to stop dangerous mental breaks, prevent colonists from leaving the colony, or facilitate forced religious conversion.
In the complex ecosystem of RimWorld, management goes far beyond simply assigning work priorities and scheduling recreation. As a colony overseer, you often find yourself in positions where the "soft" power of suggestion and schedule is insufficient to maintain order. In these moments, the game’s "Arrest" mechanic becomes an essential tool for survival. Whether you are dealing with a chemical-fascinated colonist about to binge on your entire supply of Luciferium or a pawn who has decided to leave the map forever during a mid-winter snap, knowing the technical nuances of the arrest system is vital for long-term colony stability in 2026.
Prerequisites for a Successful Arrest
Before you attempt to take a member of your colony into custody, certain infrastructure and personnel requirements must be met. Attempting an arrest without these in place can lead to failed captures, escaped prisoners, or unnecessary injuries.
Designated Prisoner Housing
You cannot arrest a pawn if there is no valid place to put them. A "valid" prison space requires a room containing at least one bed or sleeping spot marked "For prisoners." In the early game, this might be a simple sleeping spot on a dirt floor in a wooden shack. In more established colonies, you should aim for a dedicated barracks or individual cells.
- Temperature Control: Ensure the prison area is heated or cooled. An arrested colonist who freezes to death or suffers heatstroke will cause a massive "Friend died" mood debuff across your entire colony.
- Enclosure: The room must be fully enclosed with walls and a door. If the door is held open, the cell is not considered valid.
The Arrester's Qualifications
While any capable pawn can be drafted and ordered to make an arrest, the Social skill of the arrester is the most critical factor. The "Arrest Success Chance" is a hidden stat influenced heavily by the pawn's Social Impact. A pawn with a high Social skill is significantly less likely to provoke a violent reaction from the target.
Furthermore, ensure the arrester is physically capable of moving. A pawn with leg injuries or high consciousness penalties (due to drugs or illness) will move slower, giving the target more time to wander away or complete a destructive action before they can be apprehended.
Step-by-Step: The Arrest Process
Executing an arrest is a manual process that requires direct player intervention. It is not an automated task that pawns will perform based on their work priorities.
- Draft the Arrester: Select a pawn (preferably one with high Social skill) and press the "Draft" key (default 'R').
- Initiate the Command: With the drafted pawn selected, right-click the target colonist.
- Select "Arrest": From the context menu, choose the "Arrest [Name]" option.
- The Escort: The arrester will approach the target. If the arrest is successful, the target will immediately stop their current activity (including mental breaks) and follow the arrester to the nearest available prison bed.
- Completion: Once the target reaches the bed, they are officially a "Prisoner" and part of the prisoner tab rather than the colonist bar.
Strategic Reasons to Arrest Your Own Colonists
Arresting a pawn is a drastic measure, but there are several scenarios where it is the most logical path to colony preservation.
1. Halting Dangerous Mental Breaks
Mental breaks are a core mechanic in RimWorld, ranging from harmless "Hide in room" behaviors to the catastrophic "Berserk" or "Tantrum" (targeting high-value items).
- Arsonists: A pawn on a fire-starting spree can burn down a wooden base in minutes. Arresting them immediately ends the spree.
- Tantrums: If a pawn decides to destroy a stack of 50 Advanced Components or a pile of Glitterworld Medicine, the economic loss is staggering. Arresting them preserves the items.
- Slaughterer: Pawns on this break will kill your farm animals or bonded pets. Arresting them saves your livestock.
2. Preventing Colonist Departure
Occasionally, a pawn may decide to "Give up and leave" due to prolonged low mood. If this pawn has valuable skills (like a Level 20 Medic or Crafter), you cannot afford to let them walk off the map. By arresting them, you keep them physically present in the colony, though you will have to re-recruit them or release them afterward.
3. Forced Ideological Conversion
In the Ideology DLC, converting a colonist to your primary belief system through "Social" interaction can take quadrums. However, a prisoner’s "Certainty" can be lowered much faster through the "Convert" prisoner interaction. Many players choose to arrest their own colonists specifically to put them in a cell and "brainwash" them into the colony's religion more efficiently.
4. Managing Biological Threats
With the Biotech and Anomaly DLCs, you may encounter situations where a colonist is possessed, infected with a mutating parasite, or undergoing a transformation. Arresting them allows you to keep them contained in a secure room while you research a cure or prepare for the outcome of the transformation.
The Risks: Resisted Arrest and Social Consequences
Arresting a colonist is not a guaranteed success, and it carries significant downsides that must be managed.
Resisted Arrest
When an arrest is attempted, there is a chance the pawn will "Resist Arrest." This is more likely if the arrester has a low Social skill or if the target is already in a violent mental state (like Berserk).
- The Result: A resisted arrest usually results in the target attacking the arrester. This can spiral into a "Social Fight" or turn the target permanently hostile until they are downed.
- Mitigation: If you absolutely must arrest a violent pawn, consider drafting multiple pawns to surround them. While only one can perform the arrest, the others are there to provide "Overwhelming Force" if a fight breaks out.
Mood and Social Debuffs
The moment a colonist is arrested, several negative mood modifiers are triggered:
- "Was Imprisoned": The arrested pawn receives a significant, long-lasting mood penalty (typically -10).
- Broken Social Ties: The arrested pawn may develop a negative social opinion of the person who arrested them.
- Colony-wide Impacts: Other colonists may receive a small, temporary mood hit for having a "Colony member imprisoned," depending on their Ideoligion and traits.
How to Reintegrate an Arrested Colonist
Once the crisis is averted, you need to get your colonist back into the workforce. There are two primary ways to do this, and choosing the wrong one can be a costly mistake.
The "Release" Method (Recommended)
If the pawn was a member of your colony before being arrested, simply go to the Prisoner Tab and select the "Release" interaction. A warden will eventually walk to the cell and open the door.
- The Effect: As soon as the pawn steps outside the prison door, they will automatically rejoin the colony. They retain their original faction membership and do not need to be re-recruited.
- Warning: Do not use this for guests or prisoners from other factions unless you actually want them to leave the map.
The "Recruit" Method
You can choose to use the "Recruit" interaction, where wardens use their Social skill to convince the prisoner to join. This is generally a waste of time for your own colonists, as "Release" achieves the same result instantly. However, you might use this if you want to use the time in prison to also "Reduce Resistance" or "Convert" them before they rejoin.
Comparison of Management Tactics
When a colonist is acting out, you have several options. Arresting is only one of them.
| Method | Best Used For | Primary Risk | Long-term Impact |
|---|---|---|---|
| Arrest | Destructive mental breaks, Arsonists, Preventing Pawns from leaving. | Resistance/Combat, -10 Mood debuff. | Instant resolution; pawn is temporarily removed from labor. |
| Anesthetize | Safe containment of potentially violent pawns (requires medicine). | Costs Medicine; pawn is unconscious for hours. | No "Imprisoned" mood debuff; very safe. |
| Beat to Downed | Last resort for Berserk pawns. | Permanent injury, death, or "Hunted" social status. | High medical cost; long recovery time. |
| Word of Serenity | High-level psychic (Royalty DLC) instantly ends mental breaks. | Costs Psyfocus and Neural Heat. | Instant fix with no mood penalty; the "Gold Standard." |
Advanced Strategies: The "Quality of Life" Prison
If you find yourself arresting colonists frequently (perhaps you are playing a high-difficulty "Strive to Survive" or "Losing is Fun" run), the quality of your prison matters. A colonist with a "Was Imprisoned" debuff is already at a high risk of another mental break the moment they are released.
To prevent a "break-release-break" cycle:
- Beauty and Comfort: Build a prison cell that is "Impressive." Use statues, high-quality beds, and nice flooring. This provides the "Slept in [Impressive] Room" mood buff, which helps offset the "Was Imprisoned" penalty.
- Fine Meals: Feed your prisoners "Fine" or "Lavish" meals while they are incarcerated.
- Recreational Access: Put a television or a chess table in the prison cell. This ensures their recreation meter is full when they rejoin the colony.
Interaction with DLC Mechanics (2026 Context)
By 2026, the various RimWorld expansions have added layers to the arrest system that players must navigate.
The Royalty DLC
The "Word of Trust" psycast can be used on your own prisoners to drastically reduce their resistance. If you are re-recruiting a colonist (perhaps for religious reasons), using a high-level psylinked pawn can make the process nearly instantaneous. Additionally, some high-ranking nobles may have "Decrees" that involve arresting or punishing certain colonists; failing to comply can lead to mood penalties for the Noble.
The Biotech DLC
Arresting is a prerequisite for "Extracting Genes" or "Extracting Ovum" if you are using your colonists as biological donors for your gene-modding programs. You must technically imprison them to use the Gene Extractor or perform certain medical procedures that they might otherwise refuse.
The Anomaly DLC
In the 2024 Anomaly expansion and its subsequent 2025/2026 patches, "Entity Containment" mechanics overlap with the arrest system. If a colonist becomes "Inhumanized" or possessed by a void entity, the standard arrest command is often the first step in the "Contain and Study" or "Exorcism" workflows provided by the expansion's specialized research tracks.
Frequently Asked Questions
Can I arrest a colonist who is currently in a Berserk mental break?
Yes, but they are guaranteed to resist. When a pawn is Berserk, they view everyone as an enemy. Attempting an arrest will lead to immediate melee combat. In these cases, it is often safer to use a "Melee Wall" (three pawns with blunt weapons) to down the colonist rather than attempting a formal arrest, as the arrest success chance drops to near zero during violent breaks.
Does arresting a colonist remove their "Inspiration"?
Yes. If a colonist has a "Frenzy" or "Creative Inspiration," the moment they are arrested and become a prisoner, the inspiration is lost. Always weigh the loss of the inspiration against the danger the pawn poses to the colony.
Why did my colonist "Walk Out" of prison immediately?
If you have a modded game or specific "Ideoligion" roles, some pawns have the ability to pick locks or bypass doors. However, in the base game, this usually happens if the door was accidentally set to "Hold Open" or if the "Release" command was given while the pawn was already moving.
Will arresting a "Guest" pawn cause a war?
If you are hosting guests from another faction (via a quest), arresting them will almost always result in a massive diplomatic penalty with that faction and will likely fail the quest. Only arrest guests if you are prepared for their home faction to become hostile.
Is there a way to avoid the "Was Imprisoned" mood penalty?
In the vanilla game, no. The penalty is a hardcoded consequence of being stripped of freedom. However, you can minimize its impact by ensuring the pawn's other needs (Beauty, Comfort, Food) are exceptionally high during and after their stay in the cell.
Final Recommendation for Colony Managers
Arresting your own colonists should be viewed as a tactical intervention, not a routine punishment. While it is the fastest way to stop an Arsonist or prevent a valuable scientist from deserting, the social and psychological fallout can linger for days.
As a best practice, always use your highest-Social pawn for the arrest to minimize the risk of a "Resisted Arrest" brawl. Once the pawn is in the cell, immediately check their health for any injuries sustained during the break or the arrest. Finally, unless you are performing a religious conversion or a gene extraction, always use the "Release" interaction rather than "Recruit" to return them to duty as quickly as possible.
