Halo: The Master Chief Collection update fixes the game's broken achievement

By Sean Carey,
Yesterday, 343 Industries rolled out an update for Halo: The Master Chief Collection that added a bunch of Xbox Series X|S enhancements to the game and saw Halo 4 join the collection on PC. However, the update also included a fix for the game's partially discontinued achievement.

The "All According to Plan" achievement in Halo: Combat Evolved Anniversary suddenly stopped unlocking for players when Halo: CE Anniversary was added to the Master Chief Collection on PC. The achievement asks players to kill all the enemies in the first encounter of "Truth and Reconciliation" without being detected. There was a method that required having a physical version of the game, uninstalling it, reinstalling it offline and meeting the requirements, but it was all a bit off a faff. According to the latest Halo: MCC patch notes, the achievement can now be "unlocked as expected."

We've seen a spike in unlocks for the achievement since the update rolled out, and several users are reporting it as unlocking correctly. With the "All According to Plan" achievement now fixed, the game can be 100% completed providing you can unlock the other 699 achievements.
