A lot of people who play games have some inner desire to also create games to share with the world. Epic Games wants to help you reach your goal by unleashing the Unreal Development Kit (UDK) for individuals and new companies to use. UDK will give new game creators access to the Unreal 3 engine for free, as well as all the other amenities you may need to get your creative juices flowing. Anyone can start building games on their PC by Downloading the UDK, gaining access to ongoing Unreal Engine 3 support and all the tools necessary to start building your games.

It appears the boycott isn't really working at all! Preorder sales for Left 4 Dead 2 are doing quite well, according to CVG's interview with Valve's Chet Faliszek. How well? Try four times the level of the original Left 4 Dead. After playing through the demo, I can easily see why; the game looks to be one of the year's best.
Maybe you are on the fence about the game, and can't decide whether to preorder? You might want to check out this video at G4TV. It's a twelve minute walkthrough of the new "realism" difficulty level. There's quite a lot of interesting information, including a few tidbits about the AI Director, which controls in-game events. The new and improved Director will monitor how well players are progressing, and alter the environment to compensate. For example, if a group of players is working well together, the amount of rainfall might increase to make shooting more difficult. A nice touch, for sure, and we can't wait to get our hands on Left 4 Dead 2 later this month.

US PlayStation owners may have just gotten their hands on Trine, and it might need a patch, but PC owners have had the game for a good four or five months now. Southpeak has released a patch for the retail edition of the game bringing it to version 1.05 and it fixes a variety of bugs.
Most of the fixes are for bugs, but there's a few technical optimizations to make the gameplay experience a lot smoother.

If you pre-purchased or plan on pre-purchasing Left 4 Dead 2 on Steam, there's a spiffy little extra you'll get if you also play Valve's Team Fortress 2. Namely you get Bill's beret from Left 4 Dead 1.
But this isn't just some cheap marketing gimmick, nope. There's a backstory.
... while conducting a science experiment on parallel dimensions, Bill's hat fell off a table into the Team Fortress universe.
And there ya have it. I would have liked to see the Heavy try to wear Rochelle's pink shirt or the Spy wield the frying pan. I suppose this will do.

Call of Duty: Modern Warfare 2 launches next week on the Xbox 360, PlayStation 3 and PC. We won't be getting a full co-op campaign, but we will be getting 23 Spec-Ops missions that are fully playable in two player local and online co-op.
The launch trailer was unveiled tonight and it'll get your blood pumpin' for the game. It's filled with tension, guns, helicopters, and big explosions all set to Eminem's "Till I Collapse."

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.

Codemasters has made good on their promise, and officially announced the first content pack for Operation Flashpoint 2: Dragon Rising. The pack is called the Skirmish pack and features two new cooperative missions for four players as well as four new maps for competitive play. There's also a new sandbox mode called Island Tour which can be played cooperatively.
The new co-op maps are called All Round Defence, which looks to be a survival mode type map with support and attack helicopters as players defend a fortified complex against waves of PLA; and Uphill Struggle has players trying to capture a bunker under heavy fire from hillside reinforcements.
Devolver Digital's Twitter account has announced that Serious Sam HD has gone gooooooooold for the PC. The PC version of the game is going to have "at least" 16 player co-op play throughout the game.
The remake of the classic game is done in Croteam's new Serious Engine 3.0 and will also be available on the Xbox Live Arcade about the same time as the PC release. Sadly the Xbox version will only support four players. At least it still has sunshine and lollipops though...right?

While EVGA has had a CO-OP line of video cards for a while now, their latest edition to the dual GPU lineup is something a bit unique. Instead of allowing SLI on a single card like most of the other co-op cards, the GTX 275 CO-OP uses a GTX 275 GPU for graphics and a GTS 250 GPU for PhysX support. PhysX allows the GPU to do advance physics processing and effects.
The advantage of this in this case, is it allows EVGA to make a cheaper card with PhysX support, and not force people to get a much more expensive full dual GPU card. Still at $350 it's no small chunk of change. I vote they bundle in a solid co-op game with PhysX support like Sacred 2: Fallen Angel.

This is madness! THIS IS CHAOS RISING!
We just received a fresh batch of screenshots for the upcoming Dawn of War 2 expansion: Chaos Rising. In it we see the demons from beneath planet Aurelia slaughtering our poor Space Marines in epic combat.
But screenshots are so 1990's. Feast your eyes then on the bloody trailer for the expansion, and then cry to the heavens as you can't play this right now. Just don't yell too loud, or one of those demons riding another demon might come and get you.
