The guys at CS-Nation have a Left 4 Dead preview up, having recently played the co-op zombie shooter.

Aaron Linde and I recently made the journey to Valve to go hands-on with Turtle Rock's cooperative zombie killer Left 4 Dead (PC, X360), which is now slated to arrive in the late summer.

We were left for dead. These are our stories.

At that point, all rational thought had long gone out the window; I was operating on pure instinct. I made mistakes that, despite all of my self-important ramblings about expertise, would have gotten me killed in the event of a genuine zombie outbreak. Oh, and this was on the normal difficulty level.

Previously scheduled to arrive during Q1 2008, the forthcoming co-op zombie shooter Left 4 Dead (PC, X360) will now hit in the late summer, Valve has revealed to Shacknews.

Developed in conjunction by Valve and newly-acquired subsidiary Turtle Rock Studios, the studios expect the game to arrive in August or September.

For more on Left 4 Dead, check back next week for our hands-on impressions.

Also on Computer & Video Games is this Left 4 Dead preview, offering hands-on impressions of the zombie shooter.

Valve has snapped up Left 4 Dead (PC, X360) developer Turtle Rock Studios, the company announced today.

The studio, responsible for parts of Counter-Strike: Condition Zero and various Counter-Strike: Source maps, will remain in Orange County, California.

"We have been seeing very strong growth with Steam and Source, our content distribution and development platforms, up over 150% over the last 12 months. Given our expectations for Left 4 Dead and our long-standing relationships with members of the Turtle Rock team, this was an easy decision. It also gives us a base from which to expand our development activities in the Los Angeles area," said Gabe Newell, president of Valve.

Added Turtle Rock Studios CEO Michael Booth, "Valve has had great success bringing in projects and teams such as Team Fortress and Portal. As I spent time working and talking with the creators of those products over the past several years, it became clear that this was the right next step for myself, my colleagues at Turtle Rock, our customers, and our products."

I played Turtle Rock and Valve's four-player co-op, zombie horrorshow Left 4 Dead recently, surviving to bring back this thrilling preview. I'll always remember those three strangers I played with and the time we shared--indoors, shooting zombies together in a PC game on a sunny September afternoon. Don't forget your flashlight.

Some survival-horror games include rationing ammunition and avoiding enemies as a way to introduce further anxiety in gameplay--not in Left 4 Dead. This is a shooter, and you're going to give every zombie you see a bloated bellyfull of buckshot.

Also on GameSpot is this Left 4 Dead preview, going hands-on with the game at EA's Summer Showcase press event. There's also a preview at IGN.

Turtle Rock Studios and Valve are teaming up to develop Left 4 Dead, a zombie-infested four-player online cooperative action game, and I recently had the opportunity to head up to Valve's offices and try out a scenario alongside a few developers. Check out my impressions.

During my play session, we went through an urban scenario, weaving in and out of buildings and through dark alleyways as uncharacteristically speedy zombies appeared, seemingly out of nowhere. Turtle Rock founder Booth has cited Danny Boyle's 28 Days Later, with its fast-moving undead, as his favorite zombie movie, which perhaps goes to explain why Left 4 Dead's infected enemies are more spry than their traditional survival horror counterparts. The zombies' speed ends up fitting the game's format very well. Fast zombies mean that, despite the formidable amount of firepower that can be mustered by four simultaneous players, the game is always able to be frantic and overwhelming. That frantic atmosphere is intensified by the constant possibility of friendly fire, which cannot be disabled.

A new Left 4 Dead preview this morning at Computer & Video Games, where they have the PC Zone impressions of the Turtle Rock Studios developed coop zombie shooter.

"From our very early prototypes [...] we just loved the intensity and chaos of a running mob attack. Trying to survive a screaming, raging mob running full-out at your team is visceral and intense, and just never gets old."
