Call of Duty: Warzone’s stadium access code allows you to enter the stadium bunker. It is a very elaborate process and not all players will be able to get access to it without a little bit of help. Players will need to chase down multiple stadium access codes in Call of Duty: Warzone, to open the doors to the stadium.

If you head to the corner of the bar in the club lounge you will spot the door you need to open.
