Spike trap

A spike trap is a single-use trap that deals heavy damage when triggered. The damage can be fatal to humans or large animals if it is made of good materials. The base damage varies according to the material it was built from. The damage type is sharp melee, which strikes mainly on the head and torso and usually causes bleeding.

Placement

Deadfall traps cannot be placed directly next to each other or next to any other kind of trap.

Triggering and rearming

The trigger chance is 100% for enemies, but is only 10% for raiders with the nimble trait.

Colonists, tamed animals, and friendlies are aware of trap locations and will go around them if possible, though if they walk through one they only have a very slight chance (0.4%) of triggering it. Wandering wild animals also sense and avoid traps. Manhunter animals lose their ability to sense and avoid traps.

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

Once a spike trap is triggered it is destroyed. The 'auto rearm' option, enabled by default, produces a blueprint to replace the trap.

Stats

Note: Actual armor penetration is much lower since damage is applied multiple times rather than in one single instance.
