Zombified World?

Hello,
Been wondering - is there a possibility of reviving the old gamemode “Zombified World”?
I’m not sure if there’s any actual way to get the files for it, nor what’s the fate of the content.

My after the end gamemode is basically a reboot of zombified world

course if you don’t like it or don’t want to shell out 25 shekels you can get the original zombified world here:

it’ll take a fair bit of fixing to get it up and running though
