I must admit, when I first heard of Left 4 Dead, I wasn’t really that excited about it. I mean, I don’t play FPSs all that much and I usually stay away from survival-horror games like Resident Evil (they scare me so much). But one thing seems really interesting about this: The Co-op.

There’s a nice hands-on preview of the game here My favorite paragraph from the preview:

A countdown timer appears on the screen that lets you know how long until the helicopter arrives. This is when the real fun starts. The next few minutes are spent defending yourselves from wave after wave after wave of zombie attacks, and it really offers some of the most intense and scary moments of the game. To give you an example of what happened to me, I was on the roof of the storage facility with the M16 mowing down the horde, and everything seemed to be going great. Suddenly, without warning, a Smoker tongue darted right for my neck from a nearby roof. I was caught! The tongue yanked me off the roof and I lay helpless and injured right where the zombie horde had been coming through. I screamed for help. A fellow survivor ran out from the facility, trying to beat the next wave - right when he got to me, we heard the oncoming threat. The machine gunner did all he could to cover us, but a few of them still made it past. My rescuer stopped helping me up, swung his gun, pushed back the zombies, and blasted them right in the chest. With the current danger over, he finished helping me up and we both made it safely back to the storage facility to get ready for the next wave.
The game is supposed to come out Summer 2007.
