We’d heard rumors before that Microsoft was working on an anniversary Edition of Halo 2, but it looks like the scope of Master Chief’s revival is going to be quite a bit larger on Xbox One. Sources report that HD versions of Halo 1 through Halo 4 are coming to Microsoft’s latest console with a Master Chief Edition.

The collection is coming to “refresh audiences’ memories” prior to the release of Halo 5, as reported by tech blog Engadget. No details were provided on whether the game would come out digitally or in a physical disc, nor what the expected frame-rate and resolution would be. However, it’s unlikely that the game would also include side-stories like Halo: Reach and Halo: ODST.

The developer is also unconfirmed, but 343 Industries received help on the 2011 Anniversary Edtion of the original Halo from Saber Interactive. And in a previous story, a Microsoft representative mentioned that in the “fictitious world where [Halo 2 Aniversary Edition] existed … it has to be just the multiplayer experience that we all found in that first Halo 2 game.”

We reached out to Microsoft for response, but the company does not comment on rumors and speculation.
