Metal Gear Solid 4: Guns of the Patriots Tips

Vomiting Snake
1. When you get the drum can, you can press x and roll around on its side for a little while until snake gets dizzy and has to exit the drum can in order to vomit.

2. Press start, then go into the camoflauge menu. While in the menu, use the right analog stick and turn it to the left or right. Snake will start to spin slowly, but if you keep spinning snake for a couple of seconds he'll spin faster. At this point leave the menu and get back to playing the game. As soon as you get back to the game snake will automatically vomit.
