+ Harvests anaerobes.
+ Drag is very high, making invasion a lot harder.
- Useless special building for permas, not good enough special building for rebangs (Ion Tower, cloaks the colony and defences on the planet from scanners).
- Does not harvest medicine, organics or oil by default.
- Does not support high amount of colonists in most cases.
- Does not support higher amounts of solar shots.

Unique Building: Ion Tower
