It isn't as intense as they make it out to be. I thought it was funny that they warn you a dozen times before you actually ride it, and when you go into the briefing room, you are warned again, and afterwards they ask for the people who chickened out (but they put it nicely, asking for the non-riders) and half the room ends up leaving! (Atleast when we went on!) If you are afraid of confined spaces, I don't recommend going on, as the space is extremely tight. Look at the screen, don't look around or you will definitely become a bit queasy. As for the G-force, that is what scared me the most. At first I was having trouble breathing from it and I got really scared because I had heard an instance of a little girl dying on Body Wars. But the ride is pretty neat, not as great and intense as they make it out to be. As long as you look at the screen and keep your mind focused as to what is going on in the ride you should be fine.
