Halo: The Master Chief Collection September Update Patch Notes released

The September update for Xbox One exclusive Halo: The Master Chief Collection has been released, read on for the full patch notes.

Developers 343i aimed to tackle several issues reported by fans including improving matchmaking, tweaking game rules, fixing bugs and removing exploits.

In related news the Co-creator of Halo talked about how how would’ve done the sequels to Halo 3 differently. Halo 5, the latest in the series was also rumored to be coming to PC recently.

One of the biggest changes in the Halo: The Master Chief Collection September update is with Halo: Combat Evolved. This patch will “invalidate mid-missions checkpoints for the Halo: CE campaign.” Which will result in players losing their checkpoint save from in-between missions.

343i also made changes to game rules in most of the games. Biggest of them was changing Slayer kills to 100 from 50 in Halo: Combat Evolved.
