So Happy I stumbled across this forum :) A lot of hard working speedrunners and glitchers. I am hoping to attempt a run sometime in the near future. If I use any of these I will definitely not take any credit for them. And if I stumble across anything I will post it here.
@Yoranto: that spot where you have to walk forwards and backwards is some kind of loading spot of the rest of that section. Going forwards and backwards screws that up, which probably makes the second door not spawn in. By 7-8 load points, Greg means that you have to walk 7-8 times back and forth.
I tested it this morning. I didn't test it very long but I don't think that you can hit a checkpoint because I was almost everywhere but there weren't any checkpoints.
As of 30th November 2023, New Game runs for The Last of Us/The Last of Us: Remastered must use default skins and are not allowed to have activated costum skins/backpacks/etc.
We found out that costum skins potentially change the appearances of soundglitches, which also influences the loadtimes.
