Another amazing betrayal.
Invasion. Get the core from on top of the spire - my guest jumped up and grabed it and I followed up in the falcon. I parked outside the door and guest was just about to jump in when another of my team cannoned up to the spire, only landed right on top of us as we were taking off to win the game. He died and booted us.
:/
Really there would be no problem with the betrayal system if people were just.... not idiots, who go 'oooooh X button, *press*'
