A couple more small buildings to help clutter up the table for sci-fi games.
From a cottage cheese container (the kind with some fruit in one side of the container and cottage cheese in the other), some plastic bits and a couple of the Trash Bash Bits doors. Maybe it's the entrance to an underground complex or maybe it's just a storage shed for a bunch of future tech.
Some of the not-Mechanicus warband approach the shed for mysterious reasons.
The Relay Station was made from a corner protector for some piece of electronics and a bunch of plastic bits from all over the place. It could be a communications station, some kind of atmospheric control station, or maybe even a power or sewage station.
These sci-fi ladies are on guard as their hacker does something to the Relay Station controls...
