Microsoft first announced the addition of an ATLAS to Halo Waypoint back in October. But the ATLAS didn’t show up with the Halo WayPoint Mango update that coincided with Halo Anniversary’s release. Thankfully we’ve learned today that the ATLAS is not very far off – it’s coming this Saturday, December 10.
Halo ATLAS uses maps (sponsored by Brady Games) to provide valuable multiplayer data to Halo Reach and Anniversary players. When we say Halo Anniversary players, we really mean Reach players because the non-campaign Anniversary multiplayer simply piggybacks off of Reach.
The connectivity with Reach is possible because during multiplayer games, Reach constantly sends out packets of data called heartbeats that contain gameplay status. Halo ATLAS provides a bunch of that information in near-real-time to smartphone users.
