What could possibly be better than portable zombie slaying co-op?  How about portable zombie salying co-op for the low, low price of $0.00?  Call of Duty: World At War: Zombies (now with twice the colons), one of the most popular apps for the iPhone, now has a free version.  Imaginatively dubbed "Zombies Lite", the free game allows zombie hunters to try before they buy.  However, the fun isn't unlimited: three rounds of single player and two of co-op multiplayer are offered.  By then, of course, I'm sure you'll be willing to pop the $10 for the full version.  I can't wait to put this on my brother's iPhone when he isn't looking; he's enamored of the Swine Flu Scanner and Fart apps right now...

We've been big fans of Call of Duty: World at War's Zombie mode since it was released.  We've always said, time and time again, that the four player co-op game should have had a stand alone release on the Xbox Live Arcade and PlayStation Network.  While we're still waiting for that day, we do have the next best thing - a portable iPhone/iPod Touch version with included ONLINE and local cooperative play.

PlayStation 3 and Xbox 360 owners can get their four player co-op zombie on this week for half the price in Call of Duty: World at War.  All three map packs are 50% off this week.  That gets you the three co-op maps:  Der Riese, Shi No Numa, and Verruckt - quite the bargain.  Oh sure, you also get almost a dozen other multiplayer maps, but you want to kill zombies.  We know it.

It was just about a month ago that we broke the news of the PC version of Call of Duty: World at War getting the latest map pack, chocked full of zombie goodness on the Der Riese map.  It looks like the wait is finally over, as a short but sweet message was posted on the official forums.

Like the previous patch before it, version 1.6 of Call of Duty: World at War is on the way.  Along with the normal bug fixes and tweaks, the latest map pack will be included with the patch, hopefully at no cost.  Time to grease up the mouse and keyboard for some four player co-op zombie slaying on the new Der Riese map!

If you're looking to kill some zombies, or perhaps even trounce through the second World War - and you've got a few extra nickels in your drawer - here's a Steam deal for you. 

When Nick invited me to play the newest Call of Duty: World at War Nazi Zombie map Der Riese, I was all too happy to oblige. The trouble with two-player survival games, however, is that if you're both in the same boat -- namely, the S.S. I Have No Clue -- you're not going to get very far. After several attempts to ward off the undead, we finally gave in and went in search of two more comrades in the spirit of 4-player co-op survival.

 The third map pack for Call of Duty: World at War hits Xbox Live and the PlayStation Network today, complete with a brand new co-op zombie map and monkey bombs.  To celebrate we're giving away two codes for the Xbox 360 version of the game.  

Activision and Treyarch have released the final trailer for tomorrow's Map Pack #3 for Call of Duty: World at War.  The trailer largely focuses on the game's new co-op zombie map called Der Riese, as well as showcases the game's three new multiplayer maps; Battery, Revoution and Breach.

If for nothing else, Call of Duty: World at War is going to go down in history for having the greatest co-op mode that was ever slapped onto a game: "Nazi Zombies" (Nacht der Untoten) came straight out of left field and has been providing gobs of great moments in co-op.

There's not much more to say about the latest video for the upcoming Der Riese co-op zombie map in Call of Duty: World at War.  Put simply it's rock music, exploding zombies and dogs, and lots and lots of gunfire.

According to the trailer that Treyarch just debuted for the Call of Duty: World at War Nazi Zombie co-op mode, some nifty weapons are hiding at Der Riese, weapons which will help you do just that: dispatch zombies. Shown above is the new Bowie knife, a one-hit-kill melee weapon that can be unlocked in the map.

As August nears, more Call of Duty: World at War Map Pack 3 (including Nazi Zombie map Der Riese) teasers are dropping: pictured above is a chunk of the newest wallpaper made available at CallofDuty.com this morning.

Activision and Treyarch have announced the next Call of Duty: World at War map pack.  Aptly titled "Map pack #3" - the map pack will contain three new multiplayer maps and one new zombie map.

Right on queue the Call of Duty: World at War PC patch has come out.  Version 1.5 of the patch includes a host of bug fixes as well as Map Pack #2.  This contains the next four player co-op zombie map called Shi No Numa, or Zombie Swamp.
