Which Licensed Survivor do you think showed have Voice Lines the Most?
To be honest, I think the voice lines should be a part of the Licensed Survivor's gameplay, much like Pinhead's.
It could give them a little more life so I'd be like you're playing as your favorite horror movie final girl or video game characters.
Maybe say a popular line when you perform an action, like stunning the killer or when someone heals you. Stuff like that. Maybe have them talk to each other when the killer ain't near. They just can't talk when the killer is close, just for realism.
Maybe have them say "Oh, sh*t", "d*mn it", or "Sonnuvah b*tch" when the killer finds them in a locker. INTERJECTED. I don't know really, I might be thinking out loud.
