This is the best opening to a video game ever

"BioShock" is one of the best video games of all time.

It's universally beloved by fans and critics, but it's the game's opening sequence that helped make it so iconic and memorable.

If you haven't experienced "BioShock" on the Xbox 360, PlayStation 3, or PC - or even if you have - the opening sequence sets the tone for the entire game: It's thrilling, eerie, utterly beautiful, and masterfully directed.

If you don't know much about the game, or even if you do, it's best to go into the opening sequence without knowing what's about to happen.
