I think that the game is fine with some caveats. I approached it like horror FPS with oldschool horror aesthetics. Something like a modern sequel to Undying, you can even squint at the structure as something like Undying's where you had the mansion as the central hub and different thematic areas for different adversaries, so here you have the central hub and the areas of various "lords". It's that sort of mixture of combat, exploration, upgrades in environments taking out of classic horror flicks or later films that tried to emulate those aesthetics (like Copola's Dracula or later Van Helsing), fighting the enemies that fit with that theme. As such it is fun, it's NOT Undying 2, the writing is atrocious, but it is fun enough, looks nice, runs nice and high fidelity FPSs with these aesthetics aren't exactly common.
