There won't be ground. I haven't fully tested my ideas to remove the ground but I'm sure they'll work. But I can't guarantee anything until we get to that stage
I don't suppose theres anyway to make the outside air of the map kill you if you are exposed to it is there? That would be cool. I hated how in GC you could bail outa a fighter in space, and be perfectly fine until you hit the ground.
I found a glitch in a space battle map in UT2004. For some reason I fell out of the mothership. I fell for almost two minutes before I hit the invisible ground and died. Freaky.
