Black Ops 2 Double XP and Double Weapon XP April 24 - April 27

Amidst the dark and eerie night
A choice to make – to run or fight?
The undead horde approaches fast
Armed with weapons, till the very last
In Call of Duty: World at War - Zombies
The battle for survival never ceases
A test of skill, courage and wits
As waves of zombies just never quits
Blood-soaked grounds and a burning sky
The stakes are high, the danger nigh
But in this game, we rise above
To conquer the undead with brute, tough love
With finger on the trigger and heart in hand
We face the terror, and take a stand
For in this game, we live or die
With Call of Duty: World at War - Zombies, we must survive.
