Is it possible to flip an occupied ghost by Spartan charging it like its possible to do with a warthog?
Head on, no you’ll just get splattered. At an angle, maybe. Halo 5’s physics really don’t want you to touch moving vehicles.
I have been spartan charged from the side before while in a ghost twice. The first time killed me, the second time knocked me on my side.
You can prevent being splattered by a boosting vehicle (ghost or wraith) by spartan charging it head on. I was working on my spatter coms a while back and some1 SC’ed me head on as I was boosting at him and it knocked my ghost back saving himself.
