How to unlock the M13C in MW2 and Warzone

Season five of Modern Warfare 2 added six different weapons to the game, including the M13C assault rifle, expanding on an already-massive arsenal of guns for players to choose from.

While many will get the FR Avancer and Carrack .300 from the battle pass with ease, a lot of players were looking forward to the M13C assault rifle, which was added to the game in-season a few weeks after season five launched.

If the name M13C sounds familiar, that’s because this gun is directly related to the M13B, the AR that was added to MW2 and Warzone in season one at the end of 2022. This is like that gun’s little brother, but likely just as mean.

Here’s how to unlock the M13C, the second new assault rifle added to MW2 and Warzone in Season Five.

How to get M13C in MW2 and Warzone

To unlock the M13C when it first launched, players needed to complete a challenge in Shadow Siege in MW2, which is the playable event that’s all a part of the reveal of MW3.

“The .300 BLK counterpart to the M13B, this full-auto Assault Rifle is versatile and hard-hitting as a main weapon or sniper support secondary,” Activision said.

Now that the Shadow Siege event is over, however, there’s a new challenge to unlock the M13C that can be done in-game. It’s an easy one that can be finished quite quickly once you know how to do it, so here’s how to get it done.

M13C unlock challenge in MW2 and Warzone

The challenge is to unlock the M13C is 35 hipfire kills with an assault rifle.

This can be done in either MW2 or Warzone, but I suggest hopping into Hardcore Shipment 24/7 to get this challenge done. You can get it finished in a game or two just by hipfiring enemies who are within mid-range, as Hardcore makes it so players have very little health.

Season five also added a new SMG, a new sidearm, and the pickaxe melee weapon as part of Season Five Reloaded, so there was plenty of content added to CoD throughout the season that lasts through August and September.

Season Five of MW2 and Warzone is set to end on Sept. 26, so the new and final season will likely begin on Sept. 27, ahead of the launch of the Modern Warfare 3 beta at the beginning of October.
