With Halo: Combat Evolved Anniversary (Halo: CEA) finally launching on PC earlier this month as part of the Halo: Master Chief Collection, developer 343 Industries has deployed a new update that adds features and resolves issues. But while the patch notes--which you can check out below--may seem small, the update is actually pretty big on Xbox One.

When initiating the update, 60 GB of hard drive space will be allocated to the game. Steam users need only a couple hundred megabytes to install the latest update.

The big draw of this patch, though, is the audio. After the update installs, an option in the "Settings" menu should appear that will let you switch between the original Combat Evolved and Combat Evolved Anniversary audio in multiplayer. This is an exciting upgrade for long-time Halo fans who want to hear the original audio.
