Saw this mod last night on a Haatfilms. Bought it in like 5 minutes. I have a few questions. If I am completely quiet, how close can I get to a zombie? If he's facing me? Also, when a zombie attacks me do other zombies around him automatically come to us or is it only when I fire a gun? One more thing, last night on my first play through, i had a zombie o two chasing me and I ducked into a house and like 3 or 4came inside. I managed to kill them all but I was bleeding, so I banaged and that stopped. However, the screen was going kinda grey and I was moving slowly and every few minutes I would collapse and a little hourglass would come up then I would get back up. What was that?? I tried morphine and painkillers but didn't seem to do much. P.S I kept seeing a lil broken chain icon pop up on my screen every once in a while, whats tht?
