As announced by Naughty Dog at the Sony press conference, Naughty Dog is partnering up with Subway restaurants for a unique Uncharted 3 promotion.
Fans of Uncharted 3 in the USA can have access to the full multiplayer experience if this October. The details of the campaign have yet to be named but I presume you will be given a code if you buy a certain combo from Subway.
Nevertheless, players will have full access to the multiplayer mode of Uncharted 3 before it’s released on November 1st.
