There's only one more day left in the Steam Holiday sale, but today's sales feature two solid co-op titles for cheap.

In recent months we've had extensive coverage on Army of Two: The 40th Day, and for good reason. See, we thoroughly enjoyed the first Army of Two quite a bit, but critically the game fell short in a few aspects.

The Phantasy Star Online franchise is almost ten years old, but Sega keeps pumping out games in the series. The latest is a portable version for the Nintendo DS called Phantasy Star 0. With plenty of co-op options and unique methods of communication we put the latest to the test in our latest review

If you've received one of many great co-op titles from this past year, you may have some questions about what kind of co-op you have in your hands or who you can play with. Our Co-Op Terminology guide is your definitive source to finding the answers to your co-op questions.

Every time we hear more about Brink, we fall in love all over again. An eight-player drop-in/drop-out campaign...SMART system...iron sights...what's not to like?

2009 is coming to a close, but not before inindating us with plenty of cooperative gaming news, reviews, previews and game releases.  Eight co-op reviews highlight the month along with plenty of coverage of Army of Two: The 40th Day.   Here's the full list of what you may have missed during all that holiday eating!

Computer and Video Games, the magazine not the site, has been around since 1991.  The site, not the magazine, has an interesting editorial about co-op gaming.  What about it?  Namely it's friggin awesome.  They tire of the ways of online versus, something that dominated the early parts of the decade.

If you got some great couch co-op titles for the holidays but lack the controllers to play with your friends and family - now is the time to stock up thanks to some deals on Amazon.com.

Call of Duty: Modern Warfare 2 sold like hotcakes, to be sure.  But that doesn't mean the game was perfect.  Though the Special Ops co-op mode is great, the real question is: why no campaign co-op?  We've said it many times before.  Apparently, we aren't the only ones that feel this way.  The Escapist has a Modern Warfare 2 review by the Micro-Machines Man-mouthed Zero Punctuation.  It's pretty hilarious, if NSFW, and one of the main points is the lack of co-op in the campaign.  For fans of Modern Warfare 2 who don't take the game so seriously, it's defintely worth checking out!  

So much goodness is jammed packed into this episode, it's hard to contain it all in a tiny little MP3 file.

For today only, you can snag Castle Crashers on Xbox Live Arcade for 560 .  Normally a 1200  point title, the four player co-op game is one that shouldn't be missed.  In fact, seeing it merely mentioned makes me want to rush home and fire up the Xbox to play.  It's been far too long since my castles were crashed!

With only a few days left in 2009, it's time once again to look back at what an awesome year it was.  There were plenty of great co-op games to play, brand new franchises were born, and tons of great content was made available for games.  All in all, looking back, it almost feels like there was more gaming than one person could digest.
