My friend & I just downloaded echo arena the other day, & while we were both able to meet up inside the lobby, we had no idea how to actually join a game together. We tried both hitting the 'search for game' button at the same time on the same kiosk however that didn't work, we were both thrown into different games. Later that night I saw two other people do the same thing but it worked for them ?? Is it just luck to end up in the same game/team with your friends ??
EDIT: I'm hearing that they will be adding a better match making system soon that allows you to join games with your friends, just gatta wait around till then I suppose
