Beating the Warzone 2 DMZ Chemist is how to get M13B assault rifle, though that's not easy, as you'll have to find and beat the boss before extracting with the gun he drops. All these stages can be tricky, but it's worth it - the M13B is one of the best Assault Rifles in the game, and once you unlock it, you'll be able to use it in every mode associated with the game, not just DMZ itself. For that reason, here's how to find and kill the DMZ Chemist boss, and get the M13B assault rifle in Warzone 2 and Modern Warfare 2 alike. We've also got some general Warzone 2 DMZ tips if you want some help overall, because who would say no to a little extra advantage?

1. Make sure you're prepared before you start

Before getting started, we recommend coming prepared with a long-range rifle, a 3 plate armor vest, and two other teammates to make this as easy as possible. Defeating the Chemist is doable solo, but it’ll be much harder. As you travel to the radiation zone stock up on the gear you need along the way. A UAV and a gas mask are also more or less essential.

As soon as you spawn in, open up your map and look for the radiation zone, as indicated by a yellow circle with a pink hazmat sign in the middle. The radiation zone will spawn in different locations each match. This area will typically spawn far away from your starting location, so you should be prepared for the long journey ahead. 

Then, we recommend jumping in the nearest vehicle to reach your destination. Keep in mind, the large cargo truck is the best choice, as it’ll offer plenty of protection as you make your way to the radiation zone.

3. Drive around radiation zones to locate the Chemist

As expected, if you drive into the radiation zone, you’ll slowly take damage, just like being in the gas during normal battle royale. Thankfully, you can find gas masks all around the radiation zone, and sometimes, you’ll even come across durable gas masks, which last a lot longer. 

Upon arrival, you should take a look at the inside of the zone to get a sense of your surroundings. Sometimes, there will be lots of buildings and little spots for your foes to hide in, so you’ll want to be careful.

At this point, your goal is to locate the Chemist, an AI wearing a yellow hazmat suit. His spawning location changes each time, so it might take you a while to locate him. Thankfully, the bright yellow suit is easy to spot.

4. How to defeat the Chemist in DMZ

In terms of searching for the Chemist, we recommend running into the radiation zone, and taking a peek at each building. Try to clear out the enemies, if possible, before moving on to the next area. If you don’t see the Chemist, run back outside the radiation zone to allow yourself to heal. After you’ve cleared a building, move to the next, and repeat the process.

You can also drive around the inside of the radiation zone with your vehicle, but this can sometimes be very risky, as enemies can blow you up with ease.

After you’ve spotted the Chemist, there are a couple of ways to take him down. He does have much more health than a standard enemy, but not as much as a Juggernaut. One strategy is to run the Chemist over with a vehicle. This is a surefire way to take him down quickly, assuming the Chemist is outside. If he goes inside (like he did for us), you’ll need to use a different method.

You can also use explosives on the Chemist to defeat him. We used a mix of grenades and regular weapons to deal damage, and the Chemist went down in no time at all. Just be sure to clear out as many enemies as you can so you can focus fire on the Chemist.

5. Exfil with M13B

Once the Chemist goes down, run over to his body, grab the M13B, and a gas mask (if needed), and locate the nearest Exfil location. Open up the map, and you’ll want to look out for the icon of a blue person running through a door. 

Find the nearest Exfil location, and do your best to reach the closest vehicle. We recommend playing it safe at this point, so you don’t get taken out while carrying the M13B. If you do get eliminated, you’ll need to start the entire process over again.

Drive to the Exfil zone, call the helicopter, and then do your best to hide nearby to avoid getting taken out. One thing to note is that only the player holding the M13B will earn credit for unlocking it. That means, if you’re doing this with a squad, each player will need to collect the M13B separately to unlock it.

Run into the helicopter, and if you extract safely, you will have unlocked the M13B assault rifle.
