Key features

Rural England, 1940

You play Maddox Holloway, a nine-year-old boy whose father is at the front lines of World War II while a dark affliction slowly consumes his mother, twisting her into something monstrous.

Handcrafted stop-motion

The distinctive stop-motion animation is what won it the Visual Excellence Award. It creates an eerie visual identity that makes the horror feel physical rather than rendered.

Holding on to who she was

The emotional core is not the monster but the bond. Maddox has to confront what his mother is becoming while remembering who she is.
