i would like to see caves/caverns on some planets/moons, heres why: >caves could be separate biomes for more SCIENCE (if you can code biomes under biomes) >more use for rovers and lights(and the rtg), or enter via EVA and finally use your EVA lights >makes for a unique destination (duna for example is either desert or ice caps. pretty barren) >a little more challenge depending on how squad designed them(perhaps a munar cave system accessible only via a collapsed hole in the ceiling of a cavern, so you need to drop in) >certain planets could have caverns with below surface lakes(liquids or lava?) >role-play value as caves would provide defense from solar radiation for your bases >potential mission targets(obtain sample from cave on _____) Thoughts and feedback? >i see now this is under "already suggested" as "Better/More interesting planetary surfaces", but would still like a discussion.
