It has been known for a while now that Halo: Reach would be coming to Halo: The Master Chief Collection as added DLC, though it was just a question of when. Now, as per the X019 press conference, Halo: Reach will be coming to Xbox One and PC on December 3rd.
There had been indicators on November 14th that directed toward the Halo: Reach port's official release date. First, as per the website TrueAchievements, Halo: Reach's own achievements had been added to Halo: The Master Chief Collection's list of achievements. As well, Halo: The Master Chief Collection's listing on the Xbox Store shows its release date as November 3rd, while the PC version's release date is listed as December 3rd of this year, which turns out to be the port's release date.
The trailer below shows gameplay clips and cutscenes from the new and improved Halo: Reach. As determined by the trailer, there appears to be improved visuals with an improved frame rate and overall better presentation. However, the trailer doesn't show Forge mode or much multiplayer content from Halo: Reach, which will hopefully be included.
In other Halo-related events, the television show now officially has its entire cast. It had been announced in a tweet, though fans have yet to see the quality produced by the television show. Previous Halo adaptations like Halo: Nightfall haven't been total hits with audiences, so hopefully this works out for fans and everyone involved.
As for Halo: Reach's addition to The Master Chief Collection, fans will likely be happy for the game's release overall, as Halo: Reach is actually one of the more beloved games in the series, especially as Bungie's swan song. However, Halo: The Master Chief Collection was released over five years ago and players are now looking forward to Halo: Infinite. Regardless, it will be interesting to see how much 343 improved the game over its original release on the Xbox 360.
