Hyperosmia is a Tier 8 symptom exclusive to the Necroa Virus DLC. It causes the thinning of the nasal epithelium, which increases zombies' sense of smell. This increases your disease's severity.
Symptom Combos[]
In the event that the player uses this symptom in addition to Delirium, there is a possibility that the zombies will increase their ability to seek blood through their strengthened sense of smell plus a general paranoia in seeking humans, increasing the severity of the zombies around different parts of the world.[1] The combo is called "Blood in the Air".
