Can you survive the zombies?
Zombies will pile up on each other if theres too many
(Zombies build)
Zombies will break blocks
No bloat!
To get extra zombie features, please download this other plugin:
Zombies Replace Mobs | SpigotMC - High Performance Minecraft
This should be pretty much the least laggiest zombie breaking and building plugin out there.
This is a plugin made specifically for my server, and so some features may be missing. There wasn't a plugin that fit my needs well, the closest was Monster Apocalypse - long since deprecated and discontinued, so I just made my own. This plugin is much more performant and fulfills everything I ever needed out of Monster Apocalypse, cutting everything out that I didn't.
You can check out the server website here:
https://www.statesmc.us/
It will always have the latest version of my plugins on there.
