Not sure if this has been discovered yet but after you do the whole sequence break to get the tracker and Seamus gets stuck on the door of his house, I found the area he's supposed to go to is actually loaded with a second Seamus there already and it's possible to clip through the door to that area by standing on the chair beside it and sort of just hopping through, I think camera position might have something to do with it as well. Check my vod and go to around 03:37:00 (sorry twitch is broken and won't let me make a clip)

The only issue I'm facing is I can't find a way through the second door, the area beyond seems like it's loaded but Seamus is broken and won't actually walk forward to open the door and I can't find any obvious way to clip through, there are a couple of spots that might have potential but I can't figure it out. Also Doesn't look like there's a check point there and I'm not sure about quitting out as I was trying it on a complete save.

Hopefully someone can figure out a way through that second door, would be a good time save; should skip having to do the tracker thing twice.

Made a quick youtube vid so you don't have to go scrubbing through the vod

Also did it on a new game and yeah, quitting out doesn't work.

Damn, that's a nice found! Hopefully we can get to Dead End early somehow.

This has been found, check this list: https://docs.google.com/document/d/1BR5gd00za1ckZpZg-r7kqYgELEmyt5atf8hUgpCpgEY/edit?usp=sharing

Ah damn, I did think I was a bit of an easy one to not be found already, nice one for the link. I'll see about finding a way through the second door, although that sleep paralysis glitch looks like it'll leave the whole slums skip a bit redundant.

I was able to do this before I met Momo, but it didn't seem to mean anything. But thanks to you I see a use for it!

its not actually possible even if you clip through the 2nd door the slums state after the tracker cutscene only has that room loaded in anything after is not loaded in so unfortunately nothing is gonna come from it
