The gameplay is surprisingly varied. There’s a boss fight that reminds me of Alan Wake. There’s chasing of a spy.
Although the game is all-over the place. There are ghosts, which scare you, but otherwise harmless, and there are zombies, which can kill you, but can be blocked by doors. Most of the zombies are invincible. Sometimes you need to outrun them, sometimes to sneak past, sometimes beat them in QTE.
Name of Chapter 8, “In the Mouth of Darkness” would make any Lovecraft fan smile, not just me. Other chapters are also references, but this was one of the most direct ones.
