There's nothing worse than having a great game of Halo Infinite ruined by the incessant chatter or abuse of random online players. With this in mind, it's a good idea to familiarise yourself with how to mute your foes in-game so you can get on with enjoying killing them to death without having to listen to them cry for help.
In order to mute players in Halo Infinite we can't just bring up a quick scoreboard and start switching off people's mics. Instead we need to head into the game's Social Menu. Simply hit pause and bring up the in-game menu then have a look down to the bottom right corner of your screen. You should be able to see chat and social options here and pressing the share button on your Xbox controller will bring up the Social menu showing you all the players that you're currently in-game with.
Once in here you can hit the "Y" button to mute everyone in your current game at once or work through each separate gamertag pressing "A" to silence troublesome players individually.
You can also take more permanent measures by heading into the game's audio settings and jumping down to the bottom of the menu where you can fully disable all in-game chatter and text in order to enjoy the game without the need to listen to your fellow Spartan's personal problems. Enjoy the peace and quiet!
