i used the first person aiming for ocelot and found it very easy. 4 head-shots is all it takes to bring the man down. what a wuss. a good villain can take at least a dozen shots to the face before they quit.
like liquid--he was able to withstand 10 rockets, numerous punches/kicks to the head, a fall from the top of metal gear, and i don't know how many bullets from a machine gun. now that's a real villain.
btw, berny, i beat the game with the alternate ending last night. i honestly didn't think it was that sad. yeah, it's a shame merryl died, but it was for the greater good. maybe you had built up the ending too much. or maybe i'm just dead inside.
