I'm sorry the the audio.. I'm not sure how that happened.
also, this is not the first time this has happened to me, I will upload another later.
No idea what this is ment to be how is killing two people with one bullet a glitch.Whats this airborne ??You never moved off the ground.
Look at the top right... he gets the "Airborne" challenge. Couldn't read it too well on the video but I believe the challenge is to get a 2 killstreak while in mid air. He was crouched, hence the confusion.
In MW2 there was a map where if you crouched next to a particular car and didnt move and shot 2 players with any gun the same thing happend. and you didnt have to hit both at the same time either.
