You've got to raise at least one eyebrow when Valve's buddies at Turtle Rock Studios claim that with Left 4 Dead, they're out to beat Counter-Strike - but that's exactly what they're planning on doing. They're adamant that with their four-way zombie co-op survival horror extravaganza they can supersede the most widely played online shooter on the planet, and having flown to Valve, taken part in the undead slaughter and relished the sort of interdependent gameplay so rarely seen in PC games, I can say that Turtle Rock Studios have a good chance of doing just that.
