Vipers

The Vipers are a band of raiders in the Mojave Wasteland and north of Junktown.

Background
The group is a contingent of raiders that worship snakes. Ian shares that three groups raid Shady Sands, including the Vipers, Khans, and Jackals. Aradesh warns the Vault Dweller about the group, describing them as raiders who are fanatically religious.

In 2155, a group of Brotherhood of Steel soldiers pursued the Vipers, the leader of which, Maxson II, was grazed with a poisoned arrow and died. The group came into conflict with the NCR's Colonel Moore, afterward engaging in opportunistic raiding in the Mojave Wasteland.

Interactions
They wear merc outfits or metal armor and utilize grenade rifles. They are found in camps at the Horowitz farmstead, the Highway 95 Viper's encampment and the raided farmstead, with several ambushes along major roads, like Nevada 164 out of Nipton towards Searchlight or the road that branches off north, past Ranger Station Charlie to Novac. Another camp is found southeast of hidden supply cave.
