The latest patch for Call of Duty: Black Ops Cold War has boosted Weapon XP earn rates across Multiplayer and Zombies, following player complaints about slow progression. The change was revealed as part of Treyarch's latest patch notes, which detail the changes to Weapon XP as well as a few other bug fixes across Zombies and the new Nuketown '84 map. "Coming out of last week’s 2XP + 2WXP event, we’ve made some additional tuning changes to global Weapon XP earn rates across the board," the notes read.
