Call of Duty: Black Ops 3 Gets First-Ever Double Double XP Weekend
"Double XP weekend events for Call of Duty: Black Ops III are nothing new. But this weekend, Activision is shaking things up by offering the first-ever "double double" XP event, during which you can earn double XP for your character and your weap"
This started today at 10 AM PST and runs through Tuesday, February 16 at the same time.
That's a pretty liberal interpretation of "weekend," but it probably has something to do with the US President's Day holiday this coming Monday.
