Definitely recommended, but play The Cat Lady and Downfall first, in that order. This game is the 3rd in a trilogy.

A fitting ending to the Devil Came Through Here trilogy. This one is a bit lighter on the horror than the previous two, but it's very story heavy and well written. The animation and voice acting are a big step up from the previous two as well. Definitely worth a play through if you're a fan on R. Michalski's work.
