Looks reasonably great on my PC, and the premise seemed interesting as first, but it ends up being totally boring very, very fast.
Despite being supervised by Clive Barker, it's not scary at all. Despite having some demonic monsters with truly wicked designs, there are very few of them, you mostly end up fighting the same bad guys over and over again, and that gets fuck old.
Story is stupid and makes no sense, ridiculous mix of vague occult allusions, Tom Clancy and sci-fi that you will never take seriously for even a minute.
Even when the main guy dies and you get to switch on the fly over the characters with different abilities and characteristics, it just serves to add a little bit of variety, and then it all goes to waste because it's the same tedious, linear and uneventful game of Rainbow Six with demons over and over again, with a few QTE events that aren't exciting.
Avoid.
