If you own a PlayStation 3, your ass should be walking down to Subway right this instant if you haven't already. All you have to do is purchase a medium drink ($1.90 in New York monies) and you will have access to Uncharted 3's multiplayer mode, no questions asked.
Subway has recently overtaken McDonalds as the most popular fast food chain in North America, so most of you should have no problem finding a Subway restaurant to take advantage of this promotion. Each medium drink cup's code can be redeemed on a selection of Uncharted 3 multiplayer items, so stock up, just don't forget to get the damned game itself. The entire month of October to hone your Uncharted 3 fragging skills, level up, and unlock instruments of destructions. Need I say more?
