Boundary Break, a YouTube channel that looks into unused and off-limits areas left in game code, did a video on the expanded version of The Stanley Parable, and they managed to get a wonderful bit of in-character dialogue from the game’s narrator.
That’s the hook! The real reason to load it though is Boundary Break does nice work, finding out-of-bounds content in games. Also check out their recent video on Wii Sports, although note there’s an ad as part of the content. Folks gotta eat.
