Devourer of Nations

 is a challenge in Fallout: New Vegas.

Effects
It gives 100 XP, but adds no perk.

Requirements
Eat 200 human corpses using the Cannibal perk.

Using Dine and Dash to take human remains from corpses also counts towards this challenge. It is taking the human remains that counts, the remains are not required to be eaten later, just taken.
