[Comrade Rocket]

at the end of MGS if Meryl lives she gives snake her headband which gives him infinite ammo. In MGS2 at one point, Raiden asks Snake if he will be alright. So Snake points at his head and says, "Infinite Ammo." So its assumed that is the real ending of MGS.

also, if your in the cell, lay on the ground and use the Ketchup. Snake will pour it on the ground underneth him and when the guard comes in he will think its blood. So he will go into the cell and when he turns around you can take him out. Also try hiding underneth the bed. In MGS3 if you try hiding under the bed, the guard says something about not fooling him and kicks you.
