Metal Gear Solid 3: Snake Eater HD Edition Tips

How to get in a cheapshot on Volgin
When you begin the boss fight against Colonel Volgin (the one inside the Grozni Grad hangar) quickly pull up the item menu with L2 and select the fake death pill. Snake will fall over and Volgin will turn his back on you thinking your dead. Now's your chance, use the revival pill and while Volgins back is turned shoot him with your choice gun. I suggest the shotgun.

Note: This only works once.
