5. Metal Gear Solid - Meryl Silverburgh
https://www.youtube.com/watch?v=idfKCW1Cw8M While this one isn't a canonical death, this was a very shocking moment in a game filled with shocking moments, and that's a lot. This is the only game of the saga that has different endings, and the reason why this one is a very shocking one is because of why this ending was triggered. This one was unlocked by an action you made, but not in the way you expected. This event was unlocked by your "cowardiness," a moment in which you were supposed to stand out and prove yourself as a man but you failed to resist. While most of the times on this kind of games when you fail on something like this and a character suffers the consequences usually they don't die. Not in this case, she died, and it was all your fault.
