Thief is a stealth horror series. I was surprised when I played Thief because I expected a stealth game with tactical action mood and atmosphere. But when I played it, there were so many disturbing, horror, and creepy elements in it, with the occult and secret cult organizations.
The atmosphere is so spooky, with disturbing elements in the lore, and the whole environments are so uncanny and strange, with a creepy feeling to it!
