Their objective is to kill everyone, except.

Scp 049 zombie. He kills the player on contact, and may yet be coded to spawn a zombie because we are too lazy to do it now. Scp 049 has the ability to instantly turn players into cured (zombies), which makes them drop their weapons upon holding them out, it also allows them to damage npcs or players. The author of this topic has marked a post as the answer to their question.

How about giving zombies a passive or something that gradually deals damage to, and possibly slows down, human players within, and just out of, melee reach of the zombie, so. It attempts to cure the player, but upon being. After you touch someone, you gotta quickly click on their corpse.

Things didn't go as planned.
