Holy shit that game is hard on advanced. They really stepped it up for Single player more than the demo for sure. There are like 5? different campaigns with like 6 to 7 levels each I think. I'm stuck on the very last chapter of the first campaign (the continuation of the demo) and I can't get past it.

I can't wait to play this more and in co-op. I'll need a few more days before I can say for sure but I think the replay value on this game is going to be 100x better than what I originally thought. It actually takes a helluva lot more planning setting up traps and shit for the hordes that come in. AND you have to utilize a lot more weapons. Like in the demo I never used the shotty and I'm beginning to think you have to use it on this last level to survive.

Overall, I highly recommend it right now based on the single player alone.

Yeah I think I may get it. How is it on your fps? It seems like it would be a real slow down, though I do plan on getting my new parts this week.

It runs smooth as hell for me. I don't have any fps lag at all. My machine is pretty beafy though, I'm able to get 250fps constant in cod 4 so take that into consideration on fps.
