Soto was a member of the United States Armed Forces originally serving in the Mariposa Military Base.


In 2077, the soldiers of Mariposa chose to desert the Army following their discovery of the base's human experimentation. On October 27th, four days after the Great War, these soldiers performed an Exodus from the base. While most followed Captain Roger Maxson to Lost Hills, Soto and a few others chose to split from the main group and follow Sergeant Dennis Allen.[1]

Twenty days later, the group arrived at the West Tek research facility, now a large crater known as the Glow. The group entered the ruins and explored, until Jensen accidentally triggered the security system on the third level. Most of the group were killed in the resulting chaos and Soto lost one of his arms. He was able to regroup with Sergeant Allen and Camarillo on the first level, but all there ultimately died from radiation poisoning thanks to their damaged power armor.[2]


Soto is mentioned only in Fallout.

  1. "Oh, well, in the Exodus, the Brotherhood split into two groups. The group that broke away robbed the others of some of the weapons an-and went southwest. About ten years ago, we sent out knights to look for them, but all they found was ruins. No one knows what happened." – CABBOT.MSG, line 1114
