A bit of a heads up, the below trailer does touch on a few things in the intro story. Nothing that seems to spoil anything, but just in case you are one of those people who don't want to know anything about a game's story before playing, you might want to move on. Everyone else, watch and enjoy.
Who else is excited to see what AC3 has in store for us? I know that October 30th can't get here fast enough for me.
