9. The End (MGS 3)
https://www.youtube.com/watch?v=dN6C04V_aDw The End in MGS 3 is arguably one of the
greatest boss fights in the history of the series. It really feels like a battle between two great snipers (well, in my case one great sniper and one bafflingly inept sniper). Desperately scanning the dense jungle through the scope of your rifle for signs of the bald hippy is completely immersive and tense, because you know full well that he could shoot you at any moment. It can take a long time emerge victorious, so it's a good thing that you can avoid fighting him completely by either killing him beforehand or by moving time forwards a week so that he dies of old age. But only quitters would do such a thing.
