Call of Duty: Warzone Season 6 has arrived, bringing a host of new systems and weaponry. It's been six months since Infinity Ward and Raven Software's Battle Royale released, over which time it has grown and evolved with each new Season. Warzone's sixth Season adds two new guns and a Subway fast-travel system.

Verdansk's new Metro will have several different stations, positioned under some of the game's biggest hotspots. All of these stations are identical, and allow players to quickly travel from one to the next. However, the Subway also hides a secret, a new Easter egg challenge for players to discover. While it may not be quite as tricky as Warzone's Stadium Easter egg, cracking the code in the Subway can be a matter of life and death.

Making a Withdrawal

Warzone's Subway Easter egg begins at the City Hall building in Downtown. It's the biggest building in the G6 region of the map. Inside the Hall, players should jump over the bank desk, and input the code 2719 into the keypad. The floor will begin to fill with gas, so move quickly to examine the computer in the keypad room.

Make careful note of the numbers, and the plus/minus symbols that appear. Next, players should return to the main room by jumping back over the bank desk. Look at the paintings that correspond to the numbers shown on the computer, then match up the symbols on the computer to the numbers. If everything has been done correctly, then the computer will give the Subway Override Authorized message. Finally, head out for the bank, but remember to keep an eye out for other Warzone players.

Heading Underground

After receiving the Subway Override Authorized message, head to the Verdansk Airport subway station newly added to Warzone in Season 6. From there, go down onto the platform and find the side room which contains another computer. Interact with the computer to continue the Subway Override. Next, wait for a message saying "A.E. Train Arriving Soon."

Shortly afterwards, a train will arrive at the platform. Any player who boards the train will be taken to the secret bunker that contains the reward. The prize for completing the challenge is the Firebrand blueprint, a legendary variant of the Bruen MK9 light machine-gun. Check out the Call of Duty: Warzone Season 6 Roadmap to see what else is coming over the coming months.
