When units get blown up on low gravity places such as moon, asteroids and such will there pieces get launch further and possibly into orbit creating a field of debris witch will make it hard for things to land or launch from the moon or asteroid.
that would be very cool, you can't actually launch debris into orbit though because of how gravity works.
Then the sport 'shrapnel throwing' shall be created. The goal: Throw wreckage from a small asteroid or moon and hit the enemy's commander.
Mabye the visual effect will be different, but gameplay wise it should be the same. It may create an unfair game advantage for the person who is beneath the moon's debris field. Sounds like a good mod idea, if it can be balanced right.
i think he just means the explosion animation e.g. this stuff: http://www.youtube.com/watch?v=0z1m06pj ... u.be&t=35s this would be a great post production effect and would really convey the weight (no pun intended) of your world
