How do I get the Bruen Firebrand?As Geeky Pastimes explains on Twitter via a screenshot from a Discord, you will first have to go to the town hall in the city center (located in space G6 of the map). Go through the front door, take an immediate right and jump over the bank desk, then you'll find a number pad on the wall. Enter the following digits: 2 1 7 9. Following this, the room will fill with gas.
It is then that you will have to enter a new code, the latter corresponding to the images that will scroll and which will represent a specific painting. These tables are important because they indicate the numbers to be entered on the keyboard at the top and bottom.
Once this is done, you can leave the town hall and go directly to the metro station serving the airport (located in box D4 on the map). Once at your destination, go down the stairs and turn left across the platform. It is then that you will be able to activate a computer which will call a special train which will take you to a secret stop where you will find the new Bruen plan as well as other bonuses.
In order to achieve this, you will probably have to try several times, but the game is worth the effort! As a reminder, Season 6 of Call of Duty: Modern Warfare and Call of Duty: Warzone is available from this September 29, and its details can be found here.
