Just a couple planet ideas, taking some other's ideas as well.
- Inhabited Asteroids: Asteroids with structures such as control towers and hangars extruding from the rock.
- CS0 Wreckage (Someone else had the idea, but I'm too lazy to find whoever posted it.) In essence a bunch of debris surrounding the wreckage of a CS0.
- Forerunner Wreckage: Same as the CS0 mentioned previously, however it has Forerunner debris. (Fortress Class Vessels)
Sorry if there's already a thread for this.
