Playable underground layer similar to what Earth RTS 2150 had.

WHY?
- Digging and building underground factory base is fun.
- Option to do custom underground pipe, electric wiring and underground belt design other than having them in a straight path as of now.
- Underground natives (something like the current worms, or them gaining mobility).
- Defending a breach and fixing a cave-in or reinforcing the underground passage with steal frames and constructions to reinforce base
- Exploit planet's resources unnoticed by the bitters from below.
- Thermal energy!
- Relay stations
- Underground buildings, tech & vehicle
- Hey, maybe even new resource or two

2nd'ing the idea.

Much of today's infrastructure is routed below ground, such as piping, electrical/cable/fiber, steam, water, etc.

an approach would be a cut-and-cover methodology: allow the ability to cut a trench, then lay underground-capable entities (as differentiated from 'standard'), then use a new category of concrete block to cover the trench afterwards.
