We've got a brand new contest today for some sweet swag bags from the Operation Flashpoint 2 team. These military packs include a messenger bag, canteen, t-shirt and more! All you need to do is leave a simple caption on a little picture. Best of all we have 5 to give away!

It's time for another one of our famous give aways, and this one is going to be a good one. We're giving away one copy of Borderlands for the PC to two lucky winners. Why? Well we've gone ahead and updated our review with some PC impressions and needed an excuse to give out some goodies.
But how do you win? Read on.
League of Legends, the team-vs-team title that was inspired by the Warcraft III Defense of the Ancients mod, was released last week and the good folks at Riot Games provided us with a package of goodies to give away to one lucky Co-Optimus reader. Want to know what you can win and how to enter? Click the link for all the details.

Doing something a little out of the norm for Co-Optimus, we have a contest today for city building sim, Cities XL from developer Monte Cristo. Why might you ask are we giving away the keys to a city building simulator? Well it has co-op...sorta!

It's time for another Xbox 360 co-op night, and this month we're heading to the Borderlands. Find out how you can join up on Thursday, October 29th. To celebrate - we're giving away one copy of the game!

With Borderlands out next week, it's time the promotions got kicked up a notch, and that's exactly what Microsoft and Gearbox have done.
First up is an oppurtunity to win 4000 Microsoft points by simply watching a video of Borderlands. Easy enough, US Resident just need to download the "Choose your Hero" trailer from the marketplace and you're automatically entered to win one of 95 prizes of 4000 MS Points!
Next up is a play with the developers session on October 23rd on Xbox Live. There's no prizes officially announced, but knowing some of the other team members, you might just get some phat loot!
Thanks Mrxknown_JG for the tip.

We've got a bit of PAX swag to give away from the show, and believe it or not we still have a few more articles of coverage to post!
We're giving away 12 codes for a unique PAX 09 Avatar shirt on the Xbox 360. These codes are extremely rare and were ONLY handed out at the show. Want to get one? Read on to find out how.

This Thursday, September 10th, we're going to be holding an Xbox Live Co-Op night for the XBLA title Madballs in... Babo Invasion. It's a game we reviewed pretty highly, and thanks to a unique four player co-op experience, we think it's one we need to share! So much so that we're giving away 5 copies!

We just got word of a very nice sweepstakes that Namco Bandai is running to promote Invincible Tiger: The Legend of Han Tao. The co-op friendly game supports 3D technology, and the prizes form the drawing are pretty sweet: a high end, 3D ready 60" HDTV and two pairs of "shutter" 3D glasses. (Not the cheap blue and red plastic ones!) Interested in checking out Invincible Tiger in 3D? Head over to the site to enter!

Earlier this week we posted our review of Teenage Mutant Ninja Turtles: Turtles in Time Reshelled for the Xbox Live Arcade. Yes the game name is extremely long, but that doesn't make four player co-op turtle action any less fun!
We've got 4 codes for the game to giveaway to some lucky Co-Optimus readers. All you need to do is a leave a comment in this thread and tell us who your favorite turtle is. Winners will be drawn on Friday, August 21st at 8AM EDT.
