Microsoft has just released a trailer for Halo: Combat Evolved Anniversary which suggests that the beta testing phase is over and that the title of Bungie, 343 Industries and Saber Interactive could join The Master Chief Collection on PC very soon. Next up are Halo 2: Anniversary, Halo 3, Halo 3: ODST and Halo 4.
We know in fact that the different episodes of Halo: The Master Chief Collection are progressively coming out in the story chronological order. Thus, after Halo: Reach released in December 2019, it is the turn of Halo: Combat Evolved Anniversary, a version comparable to the one released in 2011 on Xbox 360 for the 10th anniversary of the title, to be released on PC. Even if no date is announced, it could be as early as March as the game's Steam page suggests.
