Unlike some of the more straightforward methods in Season 1, the Warzone 2 M13B unlock method is a bit more complicated and unlike anything we saw in the original version of the battle royale.
Normally unlock challenges involve getting a certain number of kills with a certain type of weapon and being on your merry way, but not with the M13B, Warzone Season 1's new assault rifle.

So read on to find out exactly how to get your hands on the M13B and add it to your best Warzone 2 loadout.
