Call of Duty: Warzone 2.0 is a very competitive battle royale game. Players are constantly scrambling to get an edge over others by using the meta weapons that could turn the tide of a match.

Currently, the meta weapon in the assault rifle category cannot be unlocked by progressing through Warzone or via the Modern Warfare 2 solo campaign. It is significantly tricky since it can only be unlocked in the DMZ mode.

To make matters worse, you can only find it from one of the two bosses in the DMZ and it will only spawn once in a match. Complicating things is the fact that this boss is located in the radiation zone and enemies in that area are harder to beat.

Some enterprising players are now selling the meta M13B assault rifle on eBay, while some are offering services to carry others to obtain the weapon. Don't forget, you can only unlock the weapon if you defeat and loot the "Chemist" from the radiation zone and successfully make an exfill with the rifle from the DMZ before the timer expires.

Our guide can help players in unlocking the M13B assault rifle if you need some help, but don't want to pay for a carry.
