I remember vaguely of halo 2 vehicle jacking because most people would bail out before the animation was done but the most recent halo I played (4) I remember you get kicked off and you kinda couldn’t mode correctly but still could shoot.
Anyway in H2A I got kicked off a ghost and I could not so anything. I had normal movement speed but triggers did not respond.
I have a video but I cannot post the link from my mobile device. My profile should have a link to my YouTube and it’s labeled under halo moments “5+sec delay”
