Unnatural corpse

An Unnatural Corpse is an entity that appears in your colony via events. It looks like a copy of your still-living pawns. As soon as you get the corpse, its original copy will suffer from a mood penalty as well as the corpse sometimes teleports near to it.

There is no way to get rid of the corpse as it will reappear eventually. Once it "wakes" up, it will chase and hunt its original, where the victim will be hypnotized for several seconds before their brains get consumed. The unnatural corpse is challenging to kill, similar to a Ghoul's unnatural regeneration but faster.

The only way to get rid of the corpse before it awakes is to study it which takes several days. After that, you'll get a notification that your colonist will be able to remove the shard implanted on the corpse, which will destroy it. You can still keep it around optionally to study as it gives "advanced research points" for the dark research tab.

Killing

The duplicates invincibility is limited and if you damage it enough you can break the extreme healing causing it to be killed easily. It is recommended to make sure the original colonist is far away to prevent them from being killed.^{[Needs more testing].}
