Truth in chaos secret area
In "Truth in chaos", in the room where the lasers block direct access to the areas with VX and hostages, there is a panel behind a book case that you can acces.
I was puzzled for years on what its purpose was, but earlier today i decided to find out, and it turns out that if you use one of the lights handing from the ceiling, the book case rotates open and you can disable both lasers by using the panel. Has anybody else figured this out?
I haven't seen it mentioned anywhere, not even in speedruns.
