Firstly I'd like to apologise for the many unanswered PMs over the last few days. My wife and son have the flu so I'm playing nurse as well as trying to work. I promise I'll get back to you all over the next week.
Anyway... the patch...
This patch expands upon the randomly generated zombies. Firstly, it increases the sprites used in zombie creation from 20 to a whopping 50! You will now see medical personnel zombies, police zombies, fire service zombies, and more. Secondly, the zombies spawned will now spawn with a more diverse range of speeds, health points, skills, and sight range.
