I believe people find it hard to make good zapt servers is because you have to put time an effort into the builds and lets face it a lot of people are not willing to do that with rotondos zombie mod all you have to do is spam several spawns with zombies and build 1 or 2 buildings and you have a zombie survival
You could add an option to prevent zombies from breaking bricks.
This is needed
Spitter, its the only zombie we don't have.
the spitter needs to be finished
also there needs to be an option to not have zombies respawn
in zombie mod there is an addon called set zombie target it would be nice to be able to have zombies target specific areas with events so you could make car alarms
zombies also don't seem to move until you shoot them now
