I'm getting a lot more questions about this than I anticipated, so to be clear, I'm aware that reinstalling the game or verifying game files through Steam is always an option if something breaks. That's not the entire reason for why I decided not to publish this mod. This setup requires a sourcemod, plugin, vscript, node.js program, and a modified launch script to work, and even then you have to tamper with it for it to be somewhat stable. That's a lot of moving parts (which I've only tested on Linux, mind you), and my experience shows that most people aren't nearly tech-savvy enough to be trusted with putting those parts together. It's far from just a few files to drag-and-drop into your Steam folder. I have previously had complaints from people who didn't even know you could verify game files on Steam - that's part of the reason why Spplice even exists. To this day, I still get complaints about mods being "permanently installed" when in reality the user just loaded an old save file. So while I'm sure some of you are capable of setting this up, I simply don't see that as worth it at the expense of everyone else.

My dumbass thought u could teleport from portal 1 to portal 2, still a solid idea tho

GLaDOS watching them do weird moves in portal 1: wtf portal 2: hey, wait a minute

"This game isn't very action oriented" Turrets: "Allow us to introduce ourselves... simultaneously."

i love it when he's entirely focused on one of the two games and in the other game chell is just going schizo and running around in circles strafe jumping and shooting portals in random spots

it would be so cool to see someone use this concept to make a full game

I...thought this was "I place a portal in one game, the other portal in the other game." Like, you place a blue portal in Portal 1, and it leads to Portal 2. Place an orange portal in Portal 2 and it leads to Portal 1. Its so much pain to make that, that I got SUPER excited. Im sad its not here but dont expect it to ever be.

The king of anti-climactic endings has returned.

This has got to be one of the most interesting portal 1/2 challenge

Good thing it’s relative positioning and not absolute. That would have gotten substantially weirder. …actually that sounds pretty cool.

When I clicked onto this video, I was honestly expecting something more along the lines of Portal Reloaded lol

id love to see someone perfect a speedrun of this trying to figure out which portal 1 levels are best for skipping portal 2 levels and vice versa

16:00 I'm pretty sure it's because you can't crouch jump in Portal 2.

this is really interesting and really confusing LOL would love to see a TAS of this tbh

took me a while to realise protal 1 is running on the portal 2 version of source

i was imagining the portals take you back and forth between games, that would be so cool

Glados in portal 1 watching: Since when did we start testing on high test subjects?

For those curious to try this, use the mod P1 done P2. It's not the method he used, but I will pretty much give you the same result.

imgain this in vr. so left eye is portal 1 and right eye is portal 2

This would be really cool if you overlayed the 2 ontop of eachother Because the portals relative position is synced when you fire them it would be much easier to comprehend how your getting some portal shots

I feel like this’d be really interesting for a time travel sort of game

despite the jank this is such an awesome concept and you could do so much for it in its own game

Could you imagine a version of this where when you walk through the portals you actually go into the other game, and can even bring items/lasers/pellets/bridges through?

I remember I started watching ur stream mid way through and I was so confused…. This makes so much sense now

Awesome concept!

I actually noticed they were both in the portal 2 engine really quickly because both portal gun models look exactly the same

12:36 you could have just shot another orange portal straight down lol

another spicy upload from portalrunner 🔥

this is the best video my eyeballs have ever been graced with

i would love to see speedruns of this

i didnt actually watch the ending of this so now i can see how it went

Very nice video !

Idea: *Colored Partners* This idea makes you and your coop partner be colored. With atlas being red and p-body being green. (Course 04 and course 06 will likely be skipped due to the funnel being introduced the same way as light bridges but no new elements can be interacted with in interesting and unique ways here) Red can only interact with red colored elements. Green can only interact with green colored elements. If a conflict is met, such as a green cube touching a red button, then it will be dissolved. With players, they will jam the button for a small period of time. (Basically for a few seconds after they step off the button.) Over the length of the cooperative campaign, other colors will be introduced and taught to the players through the course of several courses. These are the other colors that will be introduced after the green and red colors being shown to the players: Blue - Will be taught a little after the red and green mechanics are solidified to the player and can be interacted with by both players but have special requirements/properties. For example, cubes and balls can float when dropped. Also, blue elements can only be interacted with by blue elements. Gray (Toggle) - Will likely be taught at the beginning of course 03. This color mainly applies to cubes because a toggling door might not be the best of ideas. (Unless only able to be interacted with by a toggle cube.) Toggle cubes toggle elements at the cost of their own physical existence. So, a player can bring disable fizzler to get a portal through it and respawn the toggle cube in order to bring the toggle cube to the button which activates the exit. The player can select which element to toggle by pinging the object or through some other means. (Special parameter in course 05 in which it can disable and enable the entire chamber's elements like light bridges, funnels, gel, buttons and more.) If a toggle cube is destroyed via fizzler or by other means, then it will spawn in its origin location when respawned and act as if the world was activated. (Could be useful if you can't face the cube to ping it) Light Blue (Conversion) - Introduced in course 05. This color applies to cubes only. The cube can 'convert' a cube's color to another color of a players choosing. A conversion cube cannot interact with other elements however. This includes normal colored puzzle elements as well. A conversion cube cannot be converted to another color. Only red, green, black and normal colored cubes can be converted to another color. Black - Introduced in course 05 to teach players on how converting a black cube to a different colored cube can be used to solve a puzzle. Black elements (mainly applies to buttons) can only be interacted with objects, but not its own color. For example, a black cube cannot be put onto a black button but must be converted to a red or green cube in order to be able to interact with a button properly. Other Concepts that likely won't be added in due to their complexity or just not being fun for a player: Yellow - Yellow physical objects are destroyed upon any interaction except pushing the object of color. Yellow Elements such as a ball button must have a ball pushed onto the ball button in order to progress because if grabbed, the ball will be fizzled upon any interaction with it. Purple - An element that duplicates itself, acts as a normal cube but sort of interlocked. (Not interlinked however because a purple cube's duplicate can die, be respawned by the purple cube or destroyed temporarily by the purple cube and not die. This is only the case so a mimic cube cannot duplicate cubes infinitely with a purple cube.) Pink (Mimic) - A cube that can mimic other cube's properties but cannot mimic player colors. Originally used to get infinite height with just a spare blue cube or a blue element and a purple cube/element.

"Too complicated" he says, try me

Woahhh, the early portal 2 chaimbers are the first portal 1 chambers

This is mind boggling

3:39 new response just dropped

"we have portal reloaded at home" portal reloaded at home:

"Same shit different ass" - p2r3

The stream was crazy.

every totally normal portal runs you've been doing have been easy to follow but this is where i draw the line, you've broken barriers i didn't even know could be broken, how does he do it

Happy 1000 veiws🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉

Always so creative

i love the concept and i admit it sounds tough, but i think it's tougher for me to actually follow which game is he focusing on

what if going through the portal in one game sent you to the other and there was only 1 portal in each of the games

Portal, But Your Existence Is Non-Linear.

I have well over 100 hours in portal2 and I still wouldn’t be able to do this, my brain would melt instantly

The Portal Reloaded we never got

The interdimensional link portal gun

Portal two gameplays

Now you're thinking with Portals.

Now do 2 instances of portal two. Number 1 uses wasd right click, left click, number 2 uses up down left right f, g, both use e to use and pick up / put down

this is a awesome mod actually damn shit seems complicated to do too

the aperture science vital testing apparatus is confused why chell is jumping in the elvevator while turning left and right while also there are portal in mid earth

New strategy: Void Portaling or Void Flinging. (8:00)

Portal: adhd edition

This is the apeture science coop testing initiative if jave cohnson ran the company

Idea: Make the portal gun limited. Apparently you can beat the SP game with 100 portals, so after 100 portals (or even less if glitches are allowed), the portal gun just explodes and you can't shoot any portals anymore. Which also means that even if you get to wheatley, you can't shoot the moon portal in the end

It reminds me of that one mod

Is another good video by the pprunner

How did you manage the controller on Portal 2? What about death? Can you please open source your plugin?

The most bizarre thing about this is... running two source engine games at once

it is [4 am] and my sleeb schedule had gone ∆ |\| ∆L {[3 weeks ago]} 🍺👁️w👁️

This is so cool, but its hard to watch, and it doesn't look like your sensitivity is synchronised between games

I really wanna Portal 1 in Portal 2 now :/

yay

Someone should handcraft a portal mod that uses this split screen mechanic, the aperture science synchronous testing initiative. The game already jokes about alternative and parallel dimensions so it would be really cool if someone did that.

12:00 GUYS THERE'S SOMETHING WRONG WITH MY PORTAL COPY

i WAS sort of expecting that the azure portal would go to the orange portal in one game and then back into the other game but that doesn't actually make much sense doesi t lol

you should make a mod that is pretty much the same, except the blue portal (in portal 1) leads to the orange portal (in portal 2) and vice versa. Basically, 2 sets of portals, and instead of them leading to each other, they lead to their other game counterparts

13:07 lol

imagine if the portal was always realitive to its games, (for example, if you placed a portal in portal1 and then walked into the wall in portal1 while still moving in portal2, the portal would appear to move with the player in portal2)

Bro why do you have to upload on a school day 😭😭now I gotta wait 6 hours to see dis shi

It's like playing portals but in the 4th dimension.

you shoulda played with an eye tracker

PLEASE, RELEASE THIS!!! I never play portal anymore so I don't care if it breaks my game. I don't care if its complicated, infact that's better cus then kids can't do it and break there game. PLEASE, EXPLAIN!

WOW. WOWWWW

Do it again, but playing portal epic edition

Holy shit

At first when reading the title I thought that placing a portal in P1 and one in P2 would let you switch to the other game's map lol (which btw would be doable considering both use the source engine, P1 maps shouldn't be that hard to port to P2. No idea about how portable would the scenario and Glados bossfight be though)

BRO DESERVES MOREEEEEEEEEEEEEEEEEEE MOREEEEEEEEEEEEEEEEEEE MOREEEEEEEEEEEEEEEEEEE MOREEEEEEEEEEEEEEEEEEE MOREEEEEEEEEEEEEEEEEEE SUBSCRIBERS

I lied, i did watch the video

I made it into the video

i don't gets why you would feel guilty for someone "breaking the game" when you could literally just reinstall it. unless i'm wrong.

POV: Evelyn tries to play Portal in Everything Everywhere All at Once

For some reason I thought that that was just portal rtx

I thought you were gonna play the co op alone

what if taking an orange portal teleport you to portal 1 and vice versa

Oh fiddlesticks, what now?

this mod is complicated enough but hear me out what if you did this again except co-op one person in portal 1 one person in portal 2 I know nothing about coding but I imagine to even get this to work it would be difficult but i think the result would be entertaining

imagine he went through a portal and switched games

portal but the blue portal is connected to the blue portal in portal 2 an oranges portal in portal 1 is connected orange portal in portal 2 pass from the portal switches the game. run the games in seamless mode and use a command to pause the game send the rotation data and momentum data over a control program

How, you can't have 2 source games open at the same time.

Are you sending demo inputs to portal 1?

Me when portal 1 controls portal 1 and portal 2 controls portal 2

thought you're going to make each game have 1 portal where portal 1 has the blue and portal 2 has orange, how crazy could that get? what would you have to do to even code that? is it possible?

Portal 2 but whenever you shoot a portal your portal is offset it a tiny bit

I thought this video was some kind of joke that would just be normal portal

hey i think i was in the first part of this one

oh fiddlesticks, what now?
