Thief: The Black Parade is an unofficial expansion for Thief Gold in which players assume the role of Hume, a returning convict, as he is inadvertently thrown into a web of intrigue and conspiracies.
Unfortunately this is not a standalone mod, so you will require the base game to play this expansion.
Holy shit, I can’t wait to try this. Classic Thief is one of my all time favorite stealth games.
