Huh. This is actually a lot more fun than I expected after first starting to play a couple of days ago. My latest game I managed to survive four days, but I can see going way longer if I had been smarter.
See, I couldn't find any good weapons in the first five or so houses I looted, so I had been killing things with a rolling pin and then a baseball bat. Decided I'd look at the map and see if there was anything interesting around, and found a convenience store, which had a lot of food. Unfortunately, it was either bad, or I got bitten by a zombie somewhere, because on day 3 I started getting sick. At that point I was on my way to a nearby warehouse to hopefully find a better weapon, when both my weapons broke on the way. I slept in a random tiny house, but kept getting weaker from sickness. With no weapon (I saw a pistol but left it, stuff is loud!), I resorted to walking through the neighborhood, stomping on zombies with my bare feet. It actually worked pretty well, I killed about 10 or so zombies on the way. Unfortunately, I got a little too arrogant with my feet, and got surrounded. If I hadn't been sick, I probably would have been okay, or if I kept that pistol I found, but alas. Here lies Peter Walker.
I will say though, that panic noise cuts straight to the bone. Especially once, when I was sleeping in the tiny house on the way to the warehouse, when a zombie somehow got into my totally closed house...I woke up, and it was totally dark. The only reason I noticed the zombie at all before it could bite me is because of the "PEW!" sound. Scared me half to death.
