Call of Duty: Warzone receives a whole bunch of content with Modern Warfare 4‘s Season 1 update, including the arrival of the Hajin and Zodiac maps. Players jumping in also have the chance to unlock new camos, Blueprints, and more completely for free. This includes an exclusive Blueprint for the Signal 50, which can be unlocked through a secret challenge. Here’s how to get the Unserialized Blueprint in Call of Duty: Warzone.
Note Location for the Unserialized Sniper Blueprint in COD Warzone
While you can ultimately skip this step, the hint for unlocking the Unserialized Sniper Blueprint can be found in a note inside a small building just south of the Depot POI on the Zodiac Resurgence map. If you interact with and read the note, it will say the following: “There are Weapon Trade Stations around to exchange guns for a stronger model. Show you can keep up with the arms race by making 25 trade-ins.”
If you follow the note closely, it should give you all the instructions needed to unlock this secret reward.
How to Get the Unserialized Sniper Blueprint in COD Warzone
As the note describes, to unlock the Unserialized Blueprint for free, you will need to trade 25 weapons at Weapon Trade Stations. These can be found all around each Resurgence map, meaning you are not limited to Zodiac to complete the challenge. Their locations are marked on both your mini-map and tac map.
Weapon Trade Stations allow you to swap your currently equipped weapon for one of a potentially higher rarity. However, do note that Weapon Trade Stations enter a 30-second cooldown after each use. The best way to complete this secret Blueprint challenge is to trade as many weapons as possible over the course of a few games. To do this, drop near a station, pick up any weapon, and trade it. While the cooldown is in effect, head to the next nearest Trade Station and repeat the process until you receive an alert notifying you that the challenge is complete.
Once you have completed a total of 25 weapon trades at Weapon Trade Stations in Warzone Resurgence, you will unlock the Unserialized Sniper Blueprint in Call of Duty: Warzone and Modern Warfare 4. This Blueprint is for the Signal 50, and if you have not already unlocked the weapon, it will also grant you access to it in all modes, including through the Gunsmith in the DMZ FOB, without needing to find a Weapon Manual.
