Details regarding the upcoming SOCOM: Confrontation open beta have today been revealed on the official website. If you want to get involved, there are two ways to do so. Firstly, drop $5 on a pre-order at Gamestop. This not only rewards you with an access voucher, but also allows you to invite two friends into the game as well. The Gamestop beta will begin on September 1st and run until the end of the month.
The other way of getting into the beta is to purchase the first episode of Qore. Doing so will allow you to download the beta client directly and play from September 8th until the 30th. This entire post is only relevant to Americans, though the official site does state that other territories will get acces and that this will be be announced by their representative SCE offices.
