Simply put, what do you believe the most jarring moment in any video game is? I'd advise only picking one, choose wisely. I would have to say Shepard's betrayal in MW2 was the most jarring. It came out of no where in the middle of a very intense mission, leading to the deaths of two characters you had grown to love. That moment is one of the only times I have ever gotten emotional over a video game. I was angry at Shepard and had a drive to kill him. I was sad that these two characters died after that in such an unexpected way. Price coming over the radio as the two were burned alive really sealed the deal for me, one of those help is too late moments. Heavy stuff for a game series most take for granted. Also as a side not destroying Infinity Ward was the most idiotic move Activision ever made.
