My issue is from the latest patch. Apparently when you're dead you have awesome eyesight! GOOD TO KNOW! Since the patch i've been getting aggro from zombies a mile away while crouch slow-walking. Example: Was in an industrial 2 story warehouse, on the 2nd floor, near a window, sitting still *crouched*. A zombie aggro'd from across a field. WTF? I agree with the slower moving zombies IF they moved just as fast indoors. That would create a much scarier environment. AS IS, you dont even have to be scared (of zombies) while running through the middle of a major city.
