If you watched The Sprint, you may have caught something.
“All of the maps are being done inside 343i, now.”
In Halo 4, the multiplayer maps were made by Certain Affinity. And we all know that alot of the maps weren’t as good as previous Halo maps. Well, now the maps are being completed directly by 343i and their pro-team.
Though, I still feel like Certain Affinity will design BTB and its maps.
