the final hand-to-hand battle between Old Snake and Ocelot: while the beginning of the cutscene and the interactive portion of the battle keep two geezers beating the crap out of each other outside the realm of Narm, it goes completely to hell once Snake collapses and has to use his syringe to get back on his feet. After some more fighting, OCELOT collapses and uses ANOTHER syringe to get back up. After some more fighting, BOTH men collapse and use their respective syringes AT THE SAME TIME. Then after some MORE fighting they start collapsing and STAB EACH OTHER with the syringes. Yeah, don't try this at home, kids.
