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.

Tonight we had our Gears of War 2 Co-Op night featuring the brand new maps in the Dark Corners set. To celebrate, and to help promote tomorrow night's Game with Developers event we have three codes to give away for the All Fronts Collection.
That'll net you 19 multiplayer maps and the cut scene single player co-op content. All yours for the low low price of free. Just leave a comment in this thread and we'll choose the winners by 12:01AM August 1st!

Show me whatcha got!
Remember the Twitter Contest, where you could write an in-game one-liner for Serious Sam HD? Well, now we have a contest of our own to help support the starving artist that is Sam.
John J. Dick, the voice of Serious Sam, is in a bit of a financial pickle. He's offered to record a line or phrase of your choice for a small fee. Here at Co-optimus, we want to help him out, while finding a special-edition way to introduce the Co-opticast (Podcast). But, we need your help!

Serious Sam HD is right around the corner for the PC and Xbox 360. To get the ball rolling Majesco has launched an interesting contest for the game. All you need to do is come up with a one liner for Sam to say.
So how does a budding video game writer enter a finely crafted line for a chance to hear it in Serious Sam HD? Gamers can log on to Twitter and send a brilliant tweet quip to @devolverdigital between July 15 and July 30. Croteam will choose the winning line and Devolver Digital will announce it to all followers of www.twitter.com/devolverdigital and www.twitter.com/majesco in early August.

One of the coolest features in the original Army of Two was the weapon shop. Not only could you buy new guns to use in your co-op missions, you could upgrade and customize the guns, even add gold plating. Purchasing and upgrading weapons are cool, but what if you could design one from scratch? Now you can in the latest contest from EA.
The weapon design contest for the game charges players with submitted their ultimate weapon. You'll need a picture and a 200 word description of the weapon. Once submitted the best ones will be voted on by the community, with the winner getting their gun in Army of Two: The 40th Day.
I suggest designing the Rocket Powered Feline Gun, or the Semi-Automatic Tomato Launcher.

If you read our review of Killing Floor, you know it's a pretty damn good co-op game. But like any game of its type, you are limited by the amount of maps available. Tripwire intends to do something about that, no - not by making maps themselves. Instead they have launched the "Grindhouse Map Making Contest" with winners pulling in prizes worth a total of $20,000.
Prizes also including video cards, keyboards, mice and of course cold hard cash. To win your job is to create a truly awesome cooperative map for Killing Floor. There's two waves of the contest, with the first one ending July 31st, and the second ending September 18th.
Perhaps this is a good opportunity to team up with a friend to create a truly awesome map, and then split the winnings? That's co-op on so many levels!

The Uncharted 2: Among Thieves multiplayer beta has been underway for a few weeks now, and the Co-Opticrew has been deep in the trenches with Nathan Drake. The beta consists of team deathmatch, a treasure capture mode and co-op! I'm sure you're like, "but Nick...I want to play co-op tooo!"
Well my friends, you are in luck. We're giving away 100 codes for access to this exclusive beta test! But first, lets talk about the co-op mode.
I ain't afraid of no contests! No sir, and we've got a great one for you for the upcoming Ghostbusters Video game! We've put together a top notch exclusive Ghostbusters prize pack for one lucky winner. Read on to find out how to win!
MTV Games and Pepsi are teaming up for big summer promotion for Rock Band. Beginning June 2, Rock Band fans will have the opportunity to become winners of an MTV Video Music Award. All you have to do to take home your own prestigious Moonman trophy is shoot a music video of you and your friends playing Rock Band in co-op! There is a catch however, you'll need to be playing along with one of the contest's predetermined songs. Videos can then be submitted to the contest website, where users will vote on which band totally melts faces and will be walking the red carpet at the 2009 MTV Video Music Awards.
If you upload your video by 6PM on the first day, you could even be entered to win a trip to E3 which begins the next day!

Castle Crashers is one of the greatest co-op titles on Xbox Live Arcade. Old School beat em up gameplay, charming, hilarious style, and 4 player co-op are a recipe for a good time. Apparently there are many others who share our high opinion of the game. In fact, that number is quite large: the Castle Crashers leaderboards include over 900,000 players!
To celebrate, Behemoth is running a contest. All you have to do is guess the date and time that the leaderboard reads 1,000,000 players. The prize is unknown at this time, but is promised to be "awesome, nay, SPECTACULAR!" I'm sure it will be quite amazing.
Speaking of amazing, have you checked out the adorable Castle Crashers figurines? I know at least one staff member has a set, and I think they'd look great next to my Transformers Mighty Muggs...
