Left4Dead2 Visuals Multihack

Is there a way to see the special infected without spawning and know where they will spawn?

In the chams part boss xyz comes out but it is confusing to see the infected even without generating
I hope you understand since I am using a translator

Hi, some options like esp/hitboxes or player info show ghosts

Edit: idk what version you use but latest version ghosts arent seen at all in chams

It is another hack that I am using because it has that option to see the special infected in ghosts
That's why I wanted to know if there is a way to set that option.
