Theres a few more in that game too. There's one if you do a search on google you could probably find it. It's how to make it so you don't have any fall damage from anywhere.
What you do is go to the gym that's in the first map area you start out in, in the game. Go inside the gym and do the jetpack code, and use it to go up into the ceiling of the gym, theres like a hole right infront of the door to the place. Once you get up there your supposed to go to the edge and jump off and fall till you die. Then you do some crap like save it, kill yourself and restart and then you don't die from falling anymore. Whats weird about this glitch is if you use the Jetpack to go all the way down, theres like a random shuvel down there. Also once you get on top of the gym (itll look all glitched thats how youll know) theres like an invisible box with two people stuck in it in the middle of a giant empty black proxy.
Theres also another one to go into what they call "the under world". You need to jetpack again and it's on the outside of the mountains by the train track area in the north part of the map by vegas. You go through some point in the mountain similar to this video, you just go right through. And then you can fly around underneath the map. supposedly theres spots where you can stand and shit but I don't know I only did this once.
heres a link to a page I found with a grip of glitches.
