Call of Duty recently shared an X (formerly Twitter) message that looks like an old telephone keypad or keypad. The community has managed to uncover this secret, allowing us to unlock some cool MW3 goodies for free. Here's how to get it.

As it turns out, the image shared by the dev team hints at the newly activated bunker in Warzone Battle Royale’s Urzikstan map. The image is of the bunker keypad, where you can enter a specific access code to unlock its doors and earn two unique rewards: the Purge Sequence calling card and the Sally 9mm Daemon blueprint.

To obtain the Purge Sequence calling card in MW3 and Warzone, start by playing a Warzone match using the Urzikstan map, either in the Plunder or Battle Royale game modes.

Then head to Bunker 7, located north of Old Town on the riverbank. I've marked the exact location of the bunker on the map above.
