Go to the arcade game thing selection, then go to the circut option,pick the map sential(sorry if I spelled wrong)and pick the warlord(if you havent done the magicman cheat do it so you don't have to do career).

Now begin the race and turn around and go the other way.Now when you get to where you can see a bridge behind the green arrows there should be rock and a billboard around the area.

Go to the rocks under the billboard and climb them.NOTE: be in the view where you can see your gun!!!!!.Now if you do this correctly you should be on the bridge!!.NOTE 2:if you go to far on the bridge it will disapear and you can still DIE!!!!

Happy glitching GREENDAY RULES!!!!!!
