<< Saw it a while ago. Pretty awsome. Me and a firend immediatly went and recreated it on my XBOX. Kind of hard to get it done correctly >>
Not really - it just takes a lot of time. Me and my cousins did it over Spring Break for an hour or two. Easiest to do on Silent Cartographer - get two guys in the Warthog and drive around the corner (if the Marines see you blowing their guys away they'll turn on you) - shoot them both while in the jeep, drive back, repeat. 2nd player should then kill 1st player (ie, the driver) so his grenades drop. Throw one under (from the front of the jeep) and enjoy
It's fun driving it off the top of S.C.
