I don't know how many people remember this, but about a month ago there was a link to a video of this guy jumping the warthog over cliffs, etc... I figured this would be a fun thing to try out so one day when I was bored I worked on it for awhile but I could never figure out how he got the warthog to flip so high. Its like he would kill the AI then throw a grenade under the warthog into other grenades on the ground? If anyone was actually able to accomplish this could they step by step explain how its done?
