Activision has announced a double XP event for Call of Duty: Warzone and Black Ops Cold War. Starting September 24 and running through September 27, everyone who plays Warzone and Black Ops Cold War (which have shared progression) will receive double weapon XP.

　　This double XP is for weapons only, it seems, and is not general double XP for levelling or double XP for the battle pass. As the tweet announcing this points out, double weapon XP can help you level up the dual-wield Sai weapon that you can unlock in "The Numbers" event right now.

　　Warzone is set for a major change later this year when developer Raven Software rolls out a brand-new map, Warzone Pacific, that looks to be the biggest shakeup for the battle royale game to date. In addition to a completely new environment, there is a new anti-cheat system coming.
