PC Gamer has posted a 10 minute video podcast with the best look at Left 4 Dead so far. The podcast shows an entire playthrough from the perspective of four doomed survivors, including every boss zombie: plenty of views of the Hunter, including a pounce kill (at 7:38), the Smoker, a few great pukes from the Boomer, the Tank (smashing two Survivors across a room at 6:40), and also even the Witch killing two Survivors in a split second with one shot (you can see the Survivors walking right by her at 5:08, then watch the health bars at 5:12 when two people suddenly die).
"Zombies, undead, infected… call em' what you want… they just want to eat your brains! Left 4 Dead is your new favorite game, you just don't know it yet. At PC Gamer's recent Showdown LAN, The Turtle Rock Studios/Valve crew were on hand to demo this amazing survival-horror-multiplayer-intensely-co-op masterpiece. See what happens (it ain't pretty) when the PC Gamer gang tries to survive the zombie apocalypse…again."
