Mebahel

The Antique Beasts mod takes you back 20 years to the world of Age of Mythology, adding new creatures and structures with unique mechanics for an immersive and challenging adventure.

A mod that makes hordes of zombies (or any entities, even modded ones if you configure it) to appear in your world at a random times. These zombies can resist daylight and break glass or fence blocks. Highly configurable.
