Wow....what an odd betrayel. Something like that happened to me, I went off the lift and one of my teammates was driving a vehicle and right before I landed I hit his windshield and died...
Yeah, I had absolutely no clue how i got the betrayal til i watched the replay. Since im the sniper and I was zoomed in and then it said "Betrayal" ..."WTF, the game just started"
