I Am Alive (PC) - glitches and observations
16Some final glitch video clips I have from this game for now. Skip tests and miscellaneous things.
---
0:00 - small jump glitch.
If you stand sideways near a ledge while holding down 'run', then buffer a jump and then push to another direction, you sometimes do a slightly glitched jump. The arc of the jump is roughly the same as normal, but the hero faces wrong direction during it. This seems harmless, and so far doing it is not very consistent either.
0:22 - some points in the game have somewhat shoddy collision and you can walk or run through them. Spots like these are usually found at seams or corners.
0:50 - wasted potential from the first chapter.
You could probably skip climbing a huge tower if you could make it to the other side of the ruined bridge early. I tried using the ledge trick to do this.
If you climb the ambulance and use the ledge trick, you can make it to some non-playable area on the right half of the bridge. However, from there it seems the other side is just too far away to get fully across.
Besides that, the area has a lot of insta-death collision that prevents you from getting a full running speed before trying to cross over.
1:47 - another skip idea that didn't pan out. You can "seam walk" up one of the bridge supports to get a lot of height, but it seems you can't get anywhere useful from the top.
2:26 - I did some random tests at the mall. You can use some shoddy collision to climb on top of a sign and from there land on a railing and go out of bounds.
There's a large plateau of walkable invisible collision to the center of the mall, allowing you to reach the other side of the first floor and even go past the walls to reach the subway early. However, the subway isn't loaded yet, so this doesn't help at all.
(I later found out that none of this was really new: Zavor, the resident speedrunner, had also experimented with this same out of bounds. But at least now the OoB is more publicly documented.)
4:15 - another failed skip attempt, this time at the boat. After getting the transmitter, I tried using ledge trick to get on the railing and perhaps skip some navigation using it. However, collision blocks you from moving too far while on the railing.
4:50 - while in the residential area in the chapter Fireworks, you can run on some boxes and reach a small unplayable area.
(Not on the vid: something tells me you might be able to skip most of Fireworks if you could just reach the other side of the skyscraper early. I tried out various ideas for doing this, but nothing worked out in the end.)
5:19 - one thing that I still haven't tested too much is doing ledge trick and then quickly running backwards or sideways instead of just dropping straight forward. This too can cause some unique results around the game, allowing you to fall a little inside collision or reach new OoB-areas altogether.
Here's one example from the end of Fireworks. Ledge trick + turning allows you to reach a small unplayable area inside the skyscraper. Too bad the timing for doing this is very precise. Maybe there could be some better setup for it?
