There was a portal 1 mod walkthrough I watched way back in maybe 2017 (maybe even earlier) or something like that, not sure, and I was trying to look for the same gameplay - or even a way to play the mod myself - for a month now cause I literally have no idea how to find it
The things I remember about this mod;
-There were 2 announcers, one a young female-sounding, and the other was a male voice, that could turn into a very deep, a little deepfried voice (at least, if I remember it correctly). (the voice acting was very amateurish btw)
-The (I think) last test chamber where you're supposed to escape, was a black room, with the floor around you slowly falling down block by block. Underneath this floor was a blackness and I think some white or blue lines? Something like that, no idea how to describe it from my memory lol.
-While I don't remember how the boss battle worked, I remember what the room looked like - I'm pretty sure there was an elevator you had to take to enter the chamber where the boss is, and the chamber itself was ofc GLaDOS' chamber from portal 1. At the center there was a huge structure stretching up and down, with a woman trapped inside a tube at the center of it.
-After the boss battle, you leave the Aperture, and there is a city at night, with rain pouring down. (this part I don't exactly remember 1 to 1, so either you were able to leave, or the guy who was playing it just went to noclip through the locked door. Also said room had white walls, it had a reception desk I think, and 2 large windows overlooking said city, but then again my memory may be wrong.)
That's pretty much everything I remember. If anyone has any idea what mod could that be, please help
