Obsession is a symptom in the Neurax Worm DLC. It causes severe damage to the orbital cortex, triggering OCD (Obsessive-compulsive disorder). It forces the host to obsess over a worm-related task.


There are three possible obsessions. The following are listed and described below:

Eradicating parasitic worms

The most common, which causes Neurax Worm hosts to give a boost to cure development.

Earthworm collecting

The second most common, humourous one. It does nothing to help the cure but increases infectivity(+20), it merely makes hosts obsess over earthworms.

Avoiding parasitic worms

The rarest of the three, which decreases infectivity(-20), making it lower than before evolving the symptom.
