Nix Umbra understands that horror is most potent when it remains inscrutable. Like cosmic horror, it is amorphous in shape, as indistinct as a dream, and near impossible to pin down. Playing Nix Umbra, surviving a few minutes at a time and trying to piece together its many mysteries, is as close as video games come to feeling numinous. It feels as though there’s some deep, phantasmal truth lying just out of reach, perhaps at the edge of the tree line, or somewhere in the forest’s shadowy margins. One more run and surely I’ll be able to reach out and touch whatever that is? [Polygon Recommends]
