Watched my buddy Phasma play through it a while back, and I've been itching to do some fan art, so here's Mad Father!
Basically, in Mad Father you're a little girl with a dead mommy and a cray cray daddy (Mad Scientist stuff) in an affair. Then you wake up one night and there are zombies and mutant dead things everywhere. Some weird "salesman" (who has no business doing anything in your house, WTF,) explains to you that there's a curse making all your dad's experiments come back to life. So then you go off to save your daddy.
Even though these hundreds of freaky zombies and dolls and masses of human flesh sewn together were made by him.
