I noticed that there are 6 Ghosts per team on Ice Fields, and extra 2 behind each base. I thought maybe they'd be used for Race, but I think the number of vehicles in that gametype is dynamic depending on the number of players, and I don't have a random 16 people to help me test this.
So, what's the deal with the extra two?
EDIT: Also, what controls projectiles bouncing off of walls? I'd assume it's the same thing for needles and flames, but I don't know.
EDIT 2: I just realized the first part didn't seem like it had to do with modding. I was considering switching the Ghosts with another vehicle, but wasn't sure if I'd end up with 6 or what... yeah. :\
