Bungie has confirmed its work on creating new content for Halo: Reach is over, but will continue to support the game until Microsoft and 343 Industries take the reins.

"We are not building map packs for Halo: Reach and we're not working on any engine modifications, with code pressed tightly to metal," explained the studio in its latest Weekly Update.

The blog post continued: "We're still here supporting Halo: Reach until Microsoft takes the reins. As phases of the transition (which is already under way) unfold we'll continue to work with Microsoft and 343 Industries to ensure the hand-off requires as little brainpower from you as possible, and as we nail down significant dates we'll hammer home your expectations in kind. Rest assured all sides are working diligently to make sure the transition experience is as awesome as possible."

"You can also expect us to continue infusing Halo: Reach's online game with plentiful playlist additions and upgrades, the best community-crafted maps we can get our hands on, and some outstanding community contests and events that we'll start talking more about in the weeks and months ahead."

Bungie concluded: "If you've been riding the Bungie ride for a good number of years, you already know the drill. The days and months ahead hold a ton of surprises, so stick around - we don't plan on going out with a whimper."

So that's it. Bungie created Halo content is over. The imminent Defiant Map Pack, released on March 15, has been developed by Certain Affinity, a studio formed by ex Bungie employee Max Hoberman, and Microsoft's 343 Industries.
