Treyarch Game Design Director David Vonderhaar shows you how to earn double XP in Black Ops 2 this weekend.
Treyarch has just activated the very first double XP weekend event for Black Ops 2 on all playlists on PS3, Xbox 360, and PC.
Just a reminder, you need to have Nuketown 2025 downloaded in order to gain double XP during this event. Nuketown 2025 is available in the first print copies of Black Ops 2.
Update: Not all players are gaining double XP as the comments below indicate. Also, the extra XP is received at the end of matches.
So, while Nuketown 2025 is downloading, check out this easter egg.
