Kotaku got the scoop on some new details for the Special Ops co-op missions in Call of Duty: Modern Warfare 2, several of which alleviate some of the pain of the lack of a proper co-op campaign.

Madballs in..Babo: Invasion has a new incentive to use your Madballs online. Playbrains, the masterminds behind this insanely fun co-op action, wants you to dress up your Balls with the free (for a limited time) Obsidian Magmor skin.

Last night we had our first Halo 3 Co-Op night in over a year, and I think most of the staff can give it a resounding success.  We've uploaded some photos of the action, and posted some recounts from the staff members who played.  

Gearbox has released some fresh screens for Borderlands, hot off the digital press from GamesCom in Germany.  The game is really looking gorgeous now, and it really makes us glad the art style changed.  It really makes the game stand out amongst the crowd.  

European PlayStation Network users have been enjoying this feature for some time, but now us North Americans can compare PlayStation 3 trophies via the official website.  There's a host of new features to the site along with this, my favorite which allows you to compare trophies to multiple friends.

Despite a delay until next year, the Army of Two: 40th Day media keeps on rolling.  The latest trailer unveils the game's villain, named Jonah.  Just look at that menacing grimace, the bushy eyebrows, and the pale skin.  It's definitely going to take some fancy co-op action to bring down that guy!

The Lost Planet 2 demo went up yesterday, and most of the Co-Optimus staff rushed home to play it as soon as possible.  Our impressions of the demo range from giddiness (me) to grumpiness (Mike) and everything in between.  We're interested to know: what are your thoughts on the demo?  Did it sell you a copy of the game?  Or save you $60?

Has Amazon.com ever got a deal for you! Okay, I'm not a salesperson, but Co-optimus thought you might like to know that you can pre-order Halo 3: ODST for a $15 *Amazon.com credit! Spend the standard $60 for a brand new, fully co-opable, Halo game - and get the $15 amazon.com credit toward ANOTHER wonderful co-op game (or Batman: Arkham Asylum) just by entering the code HALOODST when you check out.

You're Invited! What: Grunt Birthday Party - Official Xbox Live Co-Op Night When: August 20th @ 8:00 PM Eastern What to Bring: Your BR55 Battle Rifle

There is certain to be an abundance of "Horde Mode" style gameplay in the upcoming co-op lineup. First Halo 3: ODST's Firefight Mode, and now Rebellions Aliens Vs Predator game is getting a similar co-op mode.  

Remember when we told you about LittleBigPlanet PSP's co-op? Well unfortunately, we were misled. LittleBigPlanet on the PSP will not feature the co-op that we know and love in the cute little big world.

Still more news from Gamescom today, this time, a couple of hands on previews of Diablo III. 1UP and Kotaku both had some time with the demo, and shared their impressions.  While the actual content was the same, the previewers chose different classes, barbarian and wizard, respectively.  This gives us a bit of insight into the differences between the classes.  The barbarian was able to wade headlong through waves of enemies, while the wizard was more effective luring them out a couple at a time.
