CoD: Warzone 2 DMZ - How To Unlock Heated Madness Weapon Blueprint

Season 3 Reloaded is live in Warzone 2, and DMZ's new Koschei Complex exclusion zone has an exclusive Kastov 762 assault rifle weapon blueprint, but you'll need to find and scavenge the pieces to "build" it. Here's how you can claim the Heated Madness weapon blueprint for yourself.

How to unlock the free Heated Madness weapon blueprint

To get your hands on the colorful Heated Madness assault rifle weapon blueprint, you'll first need to visit DMZ's new Koschei Complex exclusion zone. This is a hidden area under Al Mazrah, but we have a full guide on all the different ways you can access this underground location.

From there, you'll need to locate and successfully extract five weapon parts. These don't all need to be extracted in one match of DMZ, but you'll need them all before you can unlock the blueprint.

Thankfully, this progress is shared with your teammates. So, if one teammate extracts with a weapon part, everyone in the squad will also get credit for unlocking the piece.

Where to find Heated Madness weapon parts

You'll want to reference our guide here on how to locate all four Koschei Complex access points mentioned below, and how to complete each puzzle room.

Here are all five Heated Madness parts and where to find them:

Barrel skin

The barrel is found by accessing any entrance to Koschei Complex, and completing the puzzle room to advance to the Chemical Plant section of the building. This piece is inside one of the vents you can crawl through near the center of the room.

Optic skin

For this, you'll want the rebreather equipment. Make sure you scavenge this before attempting to loot the piece. The optic is found by entering Koschei Complex at the Taraq/Al Mazrah bridge location. You'll need to go through the first half of the swimming puzzle, and once you reach the surface for part two, follow the right side path. Watch for trip wires and AI enemies here. The path will fork again, but keep far right and there's a boarded-up hole in the wall. Bust through the hole, and dive into the flooded room with the rebreather equipped. Swim straight until you pass through a set of doors. The optic is in the back left corner of the room.

Magazine skin

For the magazine, you'll want to make sure you have a gas mask. You'll need to enter the Oasis access point, and proceed through the gas puzzle room. When you get to the last section (marked as section 1) you want to go inside the gas-filled bunker on the left with the long gas tanks. It's in the back behind the tanks.

Muzzle skin

You'll want to go through Rohan Oil, and also grab an extra car battery and jumper cables. You'll need one to access the Chemical Plant, and another set to power up another bunker door to proceed. Once inside the Chemical Plant, grab an R4D detector, which can easily be looted somewhere within the rooms of the area. Go south in the Chemical Plant until you reach the door C2.

Here you need to power it up with the battery and cables, go through the doors (the area is called Alpha Clusters) and go straight down the hall and down some stairs into another large room. Use the R4D to find a door with three glowing symbols. Then, use the R4D detector on the blackboards around the room. There are more than four, so you want to find the ones with your symbols, and note the numbers that are marked for the symbols in order to get the door code, and open up the room with the muzzle piece.

Tip: It can be hard to find all three symbols. I could only find two of mine, but I used the process of elimination to guess the third number on the keypad. You don't get locked out for multiple guesses.

Grip skin

The muzzle is by far the most difficult and time-consuming piece to find, but you can try to get the grip at the same time, as this is in the same area of the Alpha Clusters as the muzzle. For this piece, you'll need to find three AQ laptops. These are general loot scavenged around the map, so you can find them on your explorations through Koschei Complex.

In Alpha Clusters there is a pedestal of three servers with a notice that says they are inactive. Interact with the servers to connect all three laptops, and you'll hear a door nearby open. Inside the unlocked room is the grip and other good loot.

How to build the Heated Madness blueprint

You can check your unlock progress by going to the Challenge section in the game's menu, scrolling over to the DMZ tab, and selecting the Heated Madness challenge. Once you have all the pieces, you can go into the Gunsmith and select the Kastov 762 assault rifle. These weapon skin pieces will be found in the attachment sections, so you'll need to equip them in the same way. Example: Heated Madness optic skin is under the optic section of attachments. Apply all five and the blueprint is ready for use.
