To arrive at the truth, you'll need to make use of chainsaws, knives, hammers, even bottles of eyeballs to explore every inch of the terrifyingly mad mansion.
This is a remade version of the original Mad Father. In addition to updates such as a total revamping of the in-game graphics, this remake adds brand new scenes and Blood Mode: a new second playthrough which alters the story.
