This is a new glitch I've just found in Metroid Prime 3 that allows for -seven- new spots to get out of bounds. I was able to find this now that the WIP Metroid Prime series editor I'm developing has proper Prime 3 support, which lets me see trigger locations.

This is how the glitch works. The way terminal falls work in Prime 2/3 is that the rooms have a bunch of "Death Fall Spawn Points" located in various places through the room. Usually only one of these is active at a time, and when you fall into a pit, the game will respawn you at whichever one is currently active. There are triggers at specific spots in the map that activate one of them and deactivate the others, which makes you respawn at whichever part of the map you were last at.

So how is this exploitable? Well, in Elysia, there are a lot of rooms where all of the spawn points are inactive by default. There's triggers covering each door into the room that activates the spawn point next to that door. This would be fine, except for some reason Retro made it so the triggers only cover the lower half of the door. So I found out that if you do a tricky boost SSJ through the door, you can make it through the top half without touching the trigger in the lower half, therefore avoiding activating any of the spawn points. When you fall into a pit and there are no active spawn points, the game won't respawn you and you'll simply keep falling until you're out of bounds.

This is what one of the triggers in Zipline Station Alpha looks like for example. It's pretty much exactly the same position/size in every room I show in the video (and also on every door in those rooms, so you can use any door, not just the one I used). http://i.imgur.com/sV28TZX.jpg

By abusing this, there are seven different rooms you can get out of bounds in:

- Zipline Station Alpha
- Zipline Station Bravo
- Hoverplat Docking Site
- Zipline Station Charlie
- Skybridge Hera
- Zipline Station Delta
- Skybridge Athene

There are two immediate uses for this. The first one is that the Zipline Station Alpha OoB entrance means there is now a MUCH easier way to get to Ghor after doing Early Elysia, which means skipping Bryyo is now much easier. The other use is that this lets you get out of bounds everywhere you'd normally need to use a zipline, which theoretically allows for a % drop in low% by skipping Grapple Swing.

I'm likely going to attempt to do the first ever MP3 16% run soon on my Twitch channel, so head over there and follow me if you're interested in watching: http://www.twitch.tv/parax0
Thread title: 
Anywhere, everywhere
Hell yes. So Brryo is entirely skippable now, right? Since Swing, Ice Missile, Hyper Ball are skipped in low% and Screw Attack can also be skipped?
You can skip Screw Attack OR a bunch of other things, don't think you can skip screw attack and still be low%
Anywhere, everywhere
I know, I didn't say that. But I think Bryyo could be entirely skipped in a non-low% run now.
Bryyo could maybe be skipped, but skipping SA is a /lot/ slower than grabbing it.

Also, I'm not really sure how the game would pan out if you never get corrupted. I'd assume phaaze would work the same, but the fights inbetween might be a bit weird?

For Any% this just makes early Elysia significantly easier, you would probably still go and get SA after Ghor and then carry on from that. Getting spider before grapple voltage is now possible, and will help in 100% but again, skipping spider in Any% would be faster overall, so no change there. Also we can get Hazard shield before Gandryda, and change our PH route quite a bit.

Also for 100%, if someone can find a good way to get the Temple of Bryyo missile without Nova beam and Hazard shield, in 100% you could do Early Elysia, and then do all of Bryyo Fire once you get Plasma, meaning you don't have to come back during cleanup. (And also you can delay Mogenar until Bryyo jungle cleanup, which needs Ship Grapple/Spider as its latest upgrade to be done (Unless you can somehow get the Colossus Vista missile from OoB? I don't think that's going to be a thing)

...Actually that wouldn't work if getting Ice Missiles from Rundas overwrites your Seekers. Anyone ever tried that?

Skipping corruption has actually been possible for a long time, even before early Elysia; if you do a wallcrawl from Hillside Vista to Hidden Court on your first trip through Bryyo and get Ship Missiles early, it disables the layer in Corrupted Pool that has the phazon plants on it, so you can proceed without ever getting the ability to corrupt yourself. Nothing weird happens on Phaaze.

With early Elysia you don't ever even need to go that way, so this trick doesn't really change anything there.

That has also been possible for a long time already since you can wallcrawl from a lot of different Elysia SWs to get Spider early (the best option being Landing Site A). This trick does make it more feasible to do it in a speedrun though. The trouble is you need to aether jump up from the bottom of Zipline Station Charlie, which takes time. Some testing is gonna be needed to find out how quickly that can be done.
So this does not work on the other planets, but in what way?  Is the trigger setting zone larger and unavoidable, or is there a default spawn point set?  If the spawn point has a default but the trigger can be SSJ'd over, is it usable for making room traversal, at least in one direction, faster?

Awesome find.  Enjoy verifying 16%.

It's really dependent on how the objects in that particular room are set up. There's nothing about this particular to Elysia, but it happens that Elysia is the only planet that has any rooms with the right configuration so that the trick is possible. Landing sites usually have the respawn point by the ship active by default, for instance, while other rooms like Gateway on Bryyo or the cargo docks on Norion have no default spawn, but the triggers that activate the spawn points are unavoidable.

Concourse Ventilation is one that really annoys me. It's the east Elysia room with the stupidly hard (but really useful) SW entrance. It actually only has one death fall spawn trigger, and it's really really easy to avoid (just hug the wall on the right after dropping down the SA shaft), but... the only spawn point is on by default, which means the trigger doesn't actually do anything and there's no effect from skipping it. It would be really useful to have an easier SW entrance there but I guess this isn't it.

I've been attempting it... I'm saved in Aurora Chamber with Boost Ball and no Grapple Swing atm. Should be able to keep going but I'm having a lot of problems with the Landing Site A SW (pre-unlock) now for some reason <_< I can't find a video of it... rekameohs seems to have posted videos of his attempts at it back in 2011 but he didn't post anything when he actually got it, and I don't know if anyone else who's done it (including me) bothered to save a video of it. I'll probably get it eventually, it's just giving me a lot of trouble at the moment.

edit:



Grapple Swing confirmed skippable. 16% is the new low%!
Congrats Parax! :D
