Dev Log: Zombie Type and Characteristics
The link above will provide the details to the Vespers update. The channel posting the video is the official account for Project 24.
I have added a new zombie type called Vespers. These pale swollen creature only spawn at night and emit a terrifying screech. These walkers make going out at night a threatening and dangerous experience. The zombies cannot see you but they sense the sounds that the players make. Night time at Camp Hope is dark so you won't see these undead mistakes before your hear them. This is designed to add challenge and threats to the nighttime environment.
