How to Unlock the M13C AR in Warzone & MW2

The Shadow Siege game mode in Call of Duty: Warzone was a limited-time reveal event for Modern Warfare 3. Players were able to unlock the M13C Assault Rilfe via this objective-based game mode. Now that the event is gone, here's how you can unlock the M13C in Warzone and Modern Warfare 2.

How to Unlock M13C in Warzone 2 after the Shadow Siege Event is Over

The easiest way to unlock M13C in Warzone & MW2 is by extracting the weapon in DMZ. Hop into the free-to-play game mode with a friend who already has the M13C unlocked. Tell them to bring the gun into the match and ask them to drop it for you. Pick the gun up, go to an exfil point, and extract on the evac helo while carrying the weapon. You'll then have successfully unlocked the M13C. This is the only method to get the weapon, as the developers haven't added an unlock challenge yet.

To unlock the M13C AR, you need to assist in killing five commanders in the Shadow Siege event of Warzone. If you play DMZ, you may know that commanders are bosses that spawn at specific locations in the deployment zone. In this event, you'll find three types of commanders: Juggernauts, Boss Choppers, and Wheelsons.

You can kill any of these bosses five times to unlock the M13C weapon. Remember, the progress will count even if you get an assist for killing a boss. The commanders appear in the second phase of the Shadow Siege event after the missiles you've captured have destroyed the Zaya Observatory.

Where to find the commanders in Shadow Siege

Reach the top of Zaya Observatory, and you'll find the Boss Chopper hovering in the sky around the radiation zone. Take out the helicopter, but beware of the missiles. The Wheelsons will be guarding the bunker entrances. I completed the challenge by eliminating the Juggernauts who keep spawning via the elevator, as you can see in the second image. Stay in that area and wait for these armored bosses to appear. You'll get a Juggernaut Inbound notification when they arrive. I suggest you bring a Rocket Launcher in your loadout to take out the bosses fast.

Some players are unable to unlock the M13C even after killing five commanders. Don't worry, as this is a known bug, and the developers are working on its fix. You can try killing ten commanders instead to see if the weapon unlocks for you. After the Shadow Siege event is over on August 21, you'll be able to M13C by completing a simple unlock challenge in MW2 and Warzone 2.
