Quamtotius Purgamentum begins in the time-honoured tradition of all Thief missions, with protagonist Garrett screaming loudly as he falls through an enormous hole. Landing inside a giant blue cube, he is immediately accosted by a half a dozen guards, some of whom spin violently in the air like a helicopter's rotors.
Garrett's only chance of survival is to crawl through one of four square holes in the cube, leading to various rooms connected by twisting corridors, illuminated in Thief's hallmark magenta. One room is a zombie-slaying arena set up by Garrett's evil twin brother, Barratt. Another contains five bottles floating in the air, and a text decal on the wall that simply reads "art".
