I know i'm probably the 100th guy to say this but i will say it anyway. Zombies should be slowed down. Not just because it's really hard to get a head shot on sonic the hedgehog zombies but that's how zombies are and should be. I'm not saying i want the game to be easy. I also believe there should be larger hordes of zombies all next to each other and that they should spawn everywhere. Imagine being in the forest with a couple friends and out of nowhere a group of like 15-20 zombies come out of the trees and start coming after you. and as you shoot them you alert more zombies nearby or slightly far away and they start heading towards your direction. You could run but that would cause more zombies to hear you and you would have to get to a building or somewhere safe to get away. I feel that this would add to the experience and really be more terrifying since the slow zombies are coming after you are in such large numbers shooting could only kill so many that there would still be left over after ammo is depleted. I can't be the only one who would prefer this because it's really annoying to stealth in town just to get caught and chased by dozens of zombies for miles and you lose track of where you were going to begin with. Well that's what i feel the game should play like. I'm not saying DO IT. i'm just giving a suggestion. :D
