Halo Infinite - How to get the Popcorn achievement

Viewing a clip in Theater is required for the "Get the Popcorn" accomplishment in Halo Infinite. Theater Mode is a long-standing Halo feature that allows you to watch and modify match records. Viewing a clip is simple, although it does necessitate some menu browsing. This is the simplest way to obtain this achievement.

How to view a clip

Skip to the second paragraph if you've already completed a Halo Infinite match. If you haven't completed a match yet, go to the Play tab in the Main Menu, select Custom Game, and then press Play. When the match has completely loaded (and you're permitted to fire your weapon), press the Menu (aka Start) button on your controller, scroll down, press End Game, and then press Okay.

Make sure you don't accidentally press Leave Match. The game will not be stored in your Match History if you do so. Return to the Main Menu once you've exited the match.

Use the Right Bumper to navigate to the Community tab on the Main Menu, then press Theater. My Match History should be an option you see. Select My Match History, then click on any of the available Films, press Watch Film, and then press Watch again to confirm. The movie will begin to play, and the achievement Get the Popcorn will be unlocked.
