Cheat: Prison Cell
When the clip in the torture room ends, The Sorrow is in the background holding a sign that reads 144.75. Put that code into your radio when you’re in the prison cell. It unlocks the door! That’s pretty good for a girl who just watches her boyfriend play video games all day long!
Another way to escape the prison cell Snake is being held in is to go into the menu and do the Snake viewer and start spinning him around. When you return to the game Snake should puke on the ground, the guard sees this and comes in, giving Snake the opportunity to knock him out.
Hint: Alt. Ocelot Video
At the end of the game when Ocelot tell you to choose a gun you can make him angry by not choosing one but when your done angering him go ahead and choose one. Don't pull the trigger and wait for him pull the trigger 6 times. You'll get a different cinematic ending.
