How to unlock the M13B and kill the Chemist in DMZ

Need to unlock the M13B in Call of Duty: Modern Warfare II DMZ? Follow this guide to find the Chemist, grab the weapon, and successfully extract.

Alright, so you want to snag the M13B in DMZ? The key to unlocking it is taking down a specific AI enemy known as the Chemist. He hangs out in the radiation zone, which you'll spot on your map with a radiation symbol. Before you even think about heading that way, you absolutely need to grab some Radiation Blockers. These are usually found in medical stashes scattered throughout the map. Trust me, you don't want to enter the radiation zone without them – you'll start taking damage pretty quickly!

Once you're in the radiation zone, expect to run into a bunch of other AI enemies. As you get closer to the Chemist's location, a notification will pop up on your screen letting everyone know he's nearby. This is similar to when other squads are attacking a Stronghold, so be ready – other players might be heading there too, all looking to unlock the M13B.

Keep pushing forward, and you'll eventually find the Chemist. He's the guy rocking the bright yellow jumpsuit. Take him down, and then you can grab the M13B right off the ground near his body. The final step is to successfully extract from the DMZ. Find an exfil location on your map, get there without getting yourself eliminated, and boom – you'll have the M13B unlocked for use in MW2, Warzone, and DMZ.

This whole process might take a few tries, especially since you'll be competing with other players for the Chemist. It can get pretty chaotic, so good luck out there!
