The Ghost is very fast but lacks defense and maneuverability. It has decent offense, but I don't use it except for going places really fast.
-If you are going off a jump and you know you will flip, press A as you jump. This will make the Ghost do a wheelie and you will not flip when you land.
-If u want to board a Ghost, simply crouch as it charges you. Unless you are on rough ground, the Ghost will speed over you and you can press X to kick them out.
-If you are up against a tank, strafe around the tank shooting constantly.
