Regions I will name
Guides and the 1.0 notes support Gravity Farms, Flourishing Desert, Moldy Tundra, Titan City, Ice Floes, Runoff Swamp, and X11-B. X11-B arrived with 1.0. Expedition Alpha is the Mycologist rescue, not a biome nickname.
Cargo Bay and Containment tie to the red keycard. That chain lives on the bunker page, because three different places get called a bunker and mixing them up sends you to the wrong door.
Hub toys, with the author’s doubt attached
A hub picture guide points at rafters left of the launch pad, a floor under the recreation sphere with four levers, a small opening right of a SAXON logo, a vent above a chip bag, a pipe you can push, and a talking mushroom. These are historical guide locations, not this site’s hands-on observations; the 1.0 hub rework may invalidate them.
The same author lists hidden upgrade shapes for Wrangler, shock grenades, Globbler, and Cycler, then says the rule is uncertain. I will not draw the shapes.
