Well, I had initially preordered Metal Gear Solid 4 hoping to get into the Metal Gear Online beta coming the 21st. . . Unfortunately I was disappointed to learn that since I preordered online and decided to receive Metal Gear Solid 4 via mail, I would not be getting into the MGO beta as you had to preorder in-store to qualify.

Until today that is.

Fill out the following form here for a chance to get a MGO Beta voucher code redeemable on the 17th. I filled it out and immediately received an email containing the voucher code. Hurry, this won’t last forever
