Curse you and your incredible Halo Par-kour. Nice jump. I doubt I'll ever pull it off though. In fact, I won't try it at the risk of: Jump>Fall>"fuuuuuuuu"
It's not that hard once you get used to ghosting. It's just, sometimes the ghost jump launches you the other way. >.>
Fios did fail to mention something. You want to jump as late as possible to hit the ghost so it pushes you back and then you uncrouch and jump.
Actually I didn't, you don't have to hit it late, I showed the way of doing it quickly for matchmaking.
