Konami has announced (via the official PlayStation Blog) that May 12 will see the release of the new Race Mission! game mode. This will see two teams pitted against each other, with the Blue Team searching for and protecting the KEROTAN target, and the Red Team searching for and protecting the GA-KO target.

This new mode will be followed on May 26 with the release of a new "Patriot" feature. Each week a select few lucky players will be given exclusive access to a 5.56mm Hand Rifle with infinite ammunition and no reload. Players will have access to these unique "Patriot" features until the next ranking update.

Konami also revealed it will be celebrating the upcoming one-year anniversary of MGS4 with even more "awesome stuff".
