“This particular serum proved one of the most challenging to develop, due to the drastically increased safeguards necessary to prevent the spread of disease throughout the entire facility. Initial tests were thought to be unsuccessful, with subjects showing no outward signs of change. Only after accidental exposure to rhinovirus did one subject's condition manifest, resulting in an unfortunate incident that killed several members of the research team. Progress on the serum was uncharacteristically slow, due to the extensive precautions put in place to prevent further incidents. Despite the setback, however, it did clearly illustrate a path forward for future formulas.”— The Whitespring bunker terminal entries

Notes[]
- Affects enemies five range units around the player character, or 6.25 range units with Strange in Numbers. This is a very small radius.
Bugs[]
Plague Walker generates sound upon damaging enemies, and will continue to do so (at 0 damage) even if no diseases are present. This negatively affects the ability to sneak in proximity to hostile NPCs.[verified]
- This has a profound impact on the sneak effectiveness of melee characters.
- Plague Walker does not prevent diseases from wearing off over time. [patched]; confirmed to be a description error in patch 25.
