A deadfall trap slows down any pawn walking over it but once tripped, it has zero path cost. The trigger chance is 80%. The damage can cause a fatality to humans or large animals if made of good materials, and is less likely to be triggered by small animals. The base damage varies according to the material is was built from. The damage type is sharp melee, which strikes mainly on the head and torso and usually causes bleeding.

When a colonist or prisoner triggers the trap, a yellow envelope alert appears to notify the player.

Colonists and friendlies are aware of their location and will go around them if possible, though if they walk through them they still have a very slight chance (0.4%) of triggering it.


Once tripped, a deadfall trap can be rearmed only by a colonist with the hauling job type. Colonists will first remove any object laying on the trap before rearming it. It is quite lengthy to rearm, and rearming speed is not affected by manipulation or any other stats.

Automatic rearming

Deadfall traps can be set to auto-rearm, which automatically designates the trap to be rearmed each time it is tripped. Setting a trap to auto-rearm should be done while it is still armed. If a trap is already tripped, turning on the auto-rearm has no immediate effect. The trap must be manually rearmed first.

Manual rearming

  1. Select a colonist with the hauling job type and right-click on the trap.
  2. Select the trap.
  3. Click Rearm trap, or press the hotkey (default M). (A trap set to rearm is indicated with a small red V.)
  4. Select a colonist with the hauling job type.
  5. Right-click the trap and select 'Prioritize rearming trap'.
