I want to do some squad to platoon sized, SciFi games, and am interested in coming up with some rules to do that, since other than the Lunar rules, for very small groups if troops, I'm not aware of any miniatures rules that might be appropriate for that. Might even want to stretch to company sized games at the top end, occasionally, though may need fast-play, streamlined rules for that.
I want to use some of the excellent, Ground Zero Games Moongrunt figures for that, along with perhaps some others too, in the larger 25mm+ sizes.
Of course, there's the Dirtside II rules also, but can't recall if they have any special rules for combat in low-G environments, dangerous atmospheres, and/or the vacuum of space.
Thinking for the vacuum/toxic side, even minor wounds can be dangerous, since suit penetrations can lead to death. Perhaps wealthy nations will provide self-sealing suits, but those on a budget might not care about their people as much.
Fights for air, water, food, and other resources seem likely far away from home, especially if resupply doesn't happen on schedule.
Throw in some aliens too, just for fun.
Anyone done this or working on it?
Thoughts, other ideas, resources?
