I vividly remember playing Thief 2 as a child, and coming to a hole in the floor leading to a dark room full of moss arrows and loot. I dropped down, thinking it was empty, and found myself trapped with no way out in a 10x10 foot room with a fucking giant spider.
I shut the computer off instantly.
Spoilered for people who haven't had the shit scared out of them by Thief yet
What the fuck, Looking Glass.
