There is a wealth of co-op opportunities out there for the co-op gamer that goes looking a little further. Muse Games' Guns of Icarus is one such title that offers a four-player co-op experience in an easy to access, and fun to play, web-browser based package.

If you read our hands on preview with Army of Two: The 40th Day on the PSP you'd know the game is quite a bit different than its console counterpart.  Now you can see it in action for yourself and the first vibe I get from the game is an updated Total Carnage.  

It's been sometime since the free online FPS Combat Arms added it's co-op mode called Fireteam.  The mode was, and is, a lot of fun - but with only one map available to play on things got stale.  Finally Nexon looks to remedy the situation not only adding a new map, but by changing things up a bit with Fireteam.

We were pretty surprised at how fun Killing Floor was when it was released earlier this year with its 6 player co-op gameplay.  At first we thought it was nothing more than a Left 4 Dead clone, but we soon came to realize the game did quite a bit to set itself apart.

Despite the demo being around since the Tokyo Game Show earlier this year, if you didn't know Japanese, you were left out in the cold from understanding the demo for Metal Gear Solid Peace Walker.  Now available for download on the PlayStation store as well as few sites scattered throughout the web, there's four missions to try in an updated version.

Also available on Xbox Live, the trailer for Splinter Cell: Conviction's co-op campaign is posted right here for you.  The trailer shows Archer and Kestrel of U.S. agency Third Echelon and Russian agency Voron - respectively - doing what they do best. Voiceovers give a synopsis, and the Splinter Cells kick rogue military personnel butt.

When thinking of games that would the word "battlefield" would befit, Grand Theft Auto IV is not usually one of them. Nevertheless, a true battlefield is not predetermined but rather just a marker for where a conflict takes place. In Grand Theft Auto IV, that happens to be wherever you can reach.

If there�s anything you can say about Q Games� PixelJunk series of games, it�s that they exemplify gameplay mechanics in their purest form. The latest entry, PixelJunk Shooter is no exception.

Crack your knuckles and get ready to fist bump!  Just a friendly reminder that Army of Two: The 40th Day's demo is out now on Xbox Live, and later today on the PlayStation Network.  The demo weigh's in at a hefty 1.8GB and features most of the first mission of the game - all available in two player co-op.

I'll admit it right off the bat: I am a serious geek for Transformers.  The latest movie was pretty much terrible, but the game based on it was surprisingly good, though it had no co-op play at all.  A new Transformers game is coming next year, called Transformers: War for Cybertron.  This new game, based on the Transformers home world before they came to Earth, will feature co-op, though the details are sparse right now.
