IMO, the demons just seem to be super zombies, which makes the 'Demons' in Zombies and Demons kind of misleading.

I was thinking the demons could have the characteristics of a demon that is illustrated in folklore(red skin, horns, etc.).

First, there should be multiple types of demons, such as imps, goblins, or hellhounds(who would require dog mods).

Second, demons should have their own attacks. For example, imps can throw fireballs and use their claws for melee.

What do you all think?
