It seems to me zombies are alright, but the panic system is not too great. Getting Panicked by a monkey zombie is simply annoying. Its not a fun mechanic and it serves no purpose other than to alert other zombies. When you start the game, you start with a pistol, beans, water, and flares. Your character obviously survived on his own for some time, he shouldn't be afraid of one or two zombies anymore. The panic should only set in when you take extensive damage or you aggro more than 10 zombies. Also, zombie spawns are simply too quick. When clearing the NW airfield hangars I get about to the end of the hangars and the zombies are already re spawning at the front of them. If you are going to keep the massive amount of zombies then tone down the spawn times. Otherewise, everything is good. Thats in my opinion however, I may be wrong.
