Konami has shut down the servers for Metal Gear Solid Online. The service, originally intended to have a 3 year life span, has shut its virtual doors after treating its fans to 4 years of wonderful(?) game play.
You can read Konami’s official adieu below.
All of the staff involved would like to offer our deepest thanks for the support we’ve gotten since launch. Thank you for coming with us on this journey. Your help allowed MGO to grow and mature. We regret that this journey must end, but we sincerely hope that we will have the opportunity to serve you again in the future.
