What is the best way of killing zombies? In the new Call of Duty: Black Ops Cold War zombie mode, you can do exactly that.

Once you upgrade the Sledgehammer to the fullest, you get to take down zombies using Thor's hammer. This article will show you how you can unlock both the Sledgehammer weapon and upgrade it to look like Thor's hammer.
Unlocking the Sledgehammer
The first requirement on getting Thor's hammer or, more specifically, a maximum level Sledgehammer, is unlocking the Sledgehammer first. To unlock the Sledgehammer, you will need to kill at least two players rapidly using the combat knife in fifteen different matches.
