Treyarch has released a new Call of Duty: Black Ops Cold War update which increases weapon XP earn rates.
Players can now level up weapons and unlock attachments faster than was previously the case in both multiplayer and Zombies.

The game’s latestupdatealso fixes an issue in Zombies that resulted in lower-than-targeted Weapon XP earn rates, and closes an out-of-bounds gap that enabled players to stay alive outside of Nuketown 84’s intended play space.
Following last week’sdouble XP event,Treyarchsaid on Monday that it’s planning further double XP events in December too.
