A long-defunct research station, X-22 focused on researching plant life and its military applications. It was here that Beauveria mordicana was created, and later transferred to Vault 22. The first subject of experiments with the plant, Patient Zero, still stalks the abandoned ruins of the facility, even after two centuries.
A long metal staircase leads from the canyon floor to a ruined building in the upper area. Red crystals, which give off light during the night, are embedded in the surrounding canyon walls. The garden is guarded by spore plants and spore carriers.
- Sink Project: Biological Research Station holotape - In the upper area of the garden, near a hot plate and a duffle bag by the staircase.
- A package with various dried seeds - On the second level of the upper area.
- Black blood sausage - On the corpse of Patient Zero.
The research station has the same number as the vault it "infected."
