So this was my game of the show for PAX, and my most anticipated game of the year now. Over an hour in line, and totally worth it. Just, wow. I'm not really into zombie games, but this one is everything I would want a zombie game to be. It totally puts you into a survival mindset, and the way it makes you play is just incredible. If you don't stick together; you die fast. I'd been following some of the coverage on this, so I was somewhat prepared. When the demo started I grabbed a sub-machine gun and immediately took up the rear guard of my four-man party, knowing that zombies could come from anywhere. While the other three charged ahead with shotguns blazing, I cautiously watched their backs, shutting doors behind us and picking off the infected that snuck up behind us. When the level opened up some, my fellow survivors started breaking rule number one, and rushing off to hunt for targets like it was an easter egg hunt. Luckily, when you're separated you can see outlines of your teammates through walls. Even better, the outlines turn red when someone is in trouble. So I was able to rush between them, covering as needed, rescuing when required. I shot more than a few Hunters off of prostrate, flailing survivors, and once when one guy got vomited on by a Boomer (also turning his outline red for a moment), I helped fight off the infected hordes that swarmed him. The whole experience was hectic and glorious. The AI Director really does a great job of keeping the intensity at the perfect level the whole time you're playing. I can't wait till this comes out; in fact I've half a mind to drive over to Valve and demand to play.
