Unlike our other news about Kingdom Hearts Birth by Sleep which is brimming with great features, I felt as if I had to notify the series' loyal fans to something which is a little different. Unfortunately the game will not feature Infrastructure Mode. Infrastructure Mode is a way of connecting with people all over the world to play games and in the case of Birth by Sleep it would be a way of playing the Mirage Arena with your friends were Infrastructure Mode available. However, the game does feature ad-hoc so you may play with your friends if you are all within a 60ft radius.
