After consuming a human corpse by way of the Cannibal perk, the Sole Survivor will automatically develop the Dark Craving. Normal food will no longer sate Hunger; the player character can only commit cannibalism to reduce their hunger and will go straight from being satisfied to ravenous instead of the intermediate states. All other foods reduce Hunger by nothing, forcing one to kill and feed off of humans as long as the addiction remains.
- The game treats this as an addiction, which can be cured by any NPC doctor.
- Addictol, refreshing beverage, and a radscorpion egg omelette will also cure the addiction.
