I don't think I could pull that off under pressure lol... Maybe if nobody was around shooting guns sure. But it is a nice jump.
its not to hard its just one ghost jump then you jump off the small bar and hopefully manage to get far enough to land on the ledge, but still nice that you pulled it off in matchmaking
