Hag snake

Hag snakes are creatures found in Burham Springs and Hoover Dam in 2253.

Characteristics
They can be encountered anywhere in the two areas, and are mutant snakes. They are descendants of the pre-War hagfish, which was a sort of leech. They move very fast and are quite large.

Appearances
Hag snakes were to appear in Van Buren, the canceled Fallout 3 by Black Isle Studios.
