There are problems that make zombie pack isn't menacing at all. When there are more than one zombie chasing the player, they will try to hit the player but end up hitting each other.
And there seems to be a limit on how many zombies can be attracted to a single player. Around 7~8. If more are attracted, the furthest zombie just sits and isn't attracted to the player anymore.
Enter elekro right after reset.
Attract every zombie in the town.
As a mass of zombie is chasing you, you get close to another zombie. But the one zombie in the 'herd' will just stop chasing you.
Run around in circles, and watch them hit each other
After the experiment, grab a fire axe and just slaughter all of them in just 30 seconds. (Yes I'm complaining about the zombie difficulty. Please make them spawn more often, and in larger numbers.)
Thank you for your report, lagrange.
This is however the intended behavior for now, for performance reasons.
Rest assured we will eventually be tweaking this - please be patient.
