In Call of Duty Modern Warfare 2 and Warzone 2, you can unlock various weapons and build different loadouts with them. Saving a custom blueprint modification was not available before, but you added it with the Season 1: Reloaded update. This allows you to set up unique weapon classes, which you can access in both multiplayer and battle royale. Here's how to build and save custom blueprints in MW2 and Warzone 2.
How to save a custom blueprint loadout in Call of Duty MW2 and Warzone 2
To save a custom-modified build, you must first select a weapon and enter the gunsmith section. Equip all five attachments and tune them to maximize the efficiency of your build. Once that's done, check the save a custom mod option on the bottom left corner of the screen. Select this option and assign a name to the custom blueprint to save it. In Warzone 2, you can get your custom loadout from Supply Drops and Strongholds. Clearing a Stronghold is relatively easier as you'll fight AI combatants to access the building.
You can check a custom-build blueprint by selecting the weapon from the Loadout section. You can also rename them accordingly to select weapon blueprints built for different game modes whenever needed. If you plan to buy a weapon loadout from the Shop (buy stations) in Warzone 2, we recommend adding your modified blueprint to the first slot of the Custom Loadouts section. Remember, only primary weapons can be purchased through the Shop, costing around $5,000. The custom blueprints can also be accessed in Warzone 2 DMZ, making it one of the best features added to the game.
