That's right. Read the title. It's a double XP weekend plus zombie Nazis! Over at the Call of Duty Headquarters, Treyarch announced that because of the success online, they presented us with these two oh so very special gifts.
Now you can play co-op zombieness with your friends even if you haven't completed the game yet. For all of you that either A. got tired of the campaign B. just bought the game and haven't beaten it yet or C. dont really care about the campaign, you aren't completely left int he dark, well you kinda are because of the horde ;)
Double XP and Zombie Nazis started earlier today at 10:00AM PST, in case you haven't heard yet. They haven't officially announced when it will end, but I suspect it will continue through Monday, at least if it still follows what IW did when they first announced their double XP weekends.
Oh, one more thing, this is for both XBox 360 and PS3.
