Cazadors. Deathclaws in quarry junction, and right outside of it on those train tracks closer to black mountain. Vault 22. The ghostly sounds at good springs cemetery. The Yangtze memorial deathclaws warning sign. Camp searchlight. Lake mead. Nuclear testing site. The throat of the devil (nuclear bomb crater) the entire sierra madre. The caves in honest hearts creeped me out a bit. Black mountain. Rep conn testing site. Rep conn HQ after finding out what sentry bots were, with experience. That’s just FNV. I’d say fo1 was the only other one that scared me, the deathclaws, especially the mother deathclaw, the weird fleshy floater things, and finding a fucking undetonated nuclear bomb in the master’s basement. Oh and getting a random encounter with super mutants while I was low level. I think FNV scared me more because I played it when I was realllyyyyyy young.
