There is actually a way how to do this. Ask Rifte Gifle. He done this with his covenent ship map. I can't remember the name but, I know you can do it because I've done it in-game on his map.
Riding the falcon is not possible with a core but standing on top is do able. as long as not standing on the blades
How did you all manage to dig this back up? As MrGreenWithAGun said you cannot use a falcon gunner seat without having driver enabled. The core carrier cannot use any vehicle regardless of what traits are set. The bomb carrier can use vehicles in accordance with the core carrier traits. I know it doesn't make sense, but that's just the way it is.
yes you have to put the game type that way though or you cant you will be stuck on top of the falcon balancing hoping not to get by the propellers REMOVED!*
