Notable loot

 * Sink Project: Biological Research Station holotape in the upper area guarded by Spore Carriers and Patient Zero, near a hot plate and a duffle bag containing some ammo among other junk.
 * A seed package with various dried seeds in the second level of the upper area guarded by Spore Carriers.
 * Broc flower, mutant cave fungus, and xander root grow nearby.
