I didn't really like Space CTF that much anyway. The kind of floater I am looking for a starship that floats over land (at night) and one flag room is on the ship-the other on the land. The only way to get to each base is by teleporter rooms. The one in the ship to get to the ground will be in a beam-portal room (like in Star Trek). The one on the ground will have it somewhere else in a bunker a while away from the flag room in a fort. And you can see the ship floating in the sky.
As you can see. I have this great idea, but sadly its never been done. I would do it, but once again, I am no good at making a sucessful map.
