FraggedNation has recently added Halo 5 to their list.
Something I felt was long overdue, but at-least it’s here now!
The singles ladder is up and running over here: http://www.fraggednation.com/standings/xboxONE/halo-5/Halo-5-Guardians-Singles-12488
I’d be happy to see some people coming in and rocking some games.
