if reachs ranks will transfer over to halo cea multiplayer or will we just start over
Halo: CEA uses the Reach’s Matchmaking system, so no, we won’t have to rank up again.
There is no transfer. For multiplayer, your not leaving Reach. Unless theres some huge glitch or something, all your ranks, commendations, achievements, etc will be the same.
Your Reach rank will always remain the same.
