Most concurrent unique users.
Bungie has announced that Halo: Reach has toppled Halo 3's record for the most concurrent unique users on Xbox LIVE.
An enthusiastic tweet from the developer last night said: "Reach already surpassed the all-time highest record for Halo 3 concurrent unique users on LIVE. Woot!"
Much is expected of Reach, but how many more of Halo 3's records will it break?
