This Halo Mod adds NATIVE Splitscreen to Halo: The Master Chief Collection on PC! (No Nucleus Co-Op) 

That fact that a mod not only added splitscreen but also made it BETTER in some ways is incredible! I can't wait for future versions which work out all of the kinks.

Siiiiick, cool that it even works for Firefight :0

Of course, modders got split screen native in MCC before 343 😂

2:00 Thank you for adding this to the tutorial, The fact that this works on Steam Deck is INCREDIBLY cool, I can just bring my dock, my deck, and 2 controllers to my friend's house and we're gonna play some FUCKING HALO SPLIT SCREEN with more ease than lugging my old Xbox 360 around.

Modding community proves once again that devs simply do not care, not that they cannot do it.

You have no idea the exorbitant amount of time you have saved me. I have spent many long nights trying to get campaign splitscreen to work with 3 people, so my friends can experience halo for the first time. Thank you very much.

I’ve been waiting for this for so long, THANK YOU SO MUCH!!!

Amazing! 2 guys with laptops and you have a 8 player party game!

I’d love a video explaining how this actually works, fascinating stuff!

This is great, holy shit. The default controls are a bit of a put off, since Universal Default SUCKS in Reach, but I'm eagerly looking forward to this.

This is awesome! Been waiting for this as a steamdeck player for a while now!

Thank you, thank you, thank you so much, to the dev and to the tester ! Me and my brother have been waiting for this since 2019

Thank you so much! I've wanted this for years! The fact that it had to be done with a mod rather than official support is just sad.

thanks for this labor of love, it'll be great for the LAN parties I want to organize with friends :DDD

Thank you for sharing this mod!!

Leaving a like and a comment for the algorithm. So many people have been waiting for something like this

this is HUGE holy moly, you guys are awesome! game-changing for machinima! hopefully character customization can be implemented!

Now if only we could get a mod that enables crossplay co-op on the halo games that don't support it.

thank you for adding a section for steam deck also! This is amazing !!

This is super exciting! Thanks for sharing this mod with the community. Now I can invite friends over to play coop campaign!

Amazing!

Had to move back in with my parents a while ago after life hit the fan hard and all I’ve had to play lately is a steam deck. I can finally play Halo with my dad again because of this, just like the early 2000’s again. I cannot tell you how happy this makes me.

Absolute legends. My brother and I can goof around in split screen whenever he visits now.

Amazing, can wait to play modded campaigns with my nephew.

HUGE THANKS , FINALLY CAN PLAY SPLITSCREEN !!

This is an insane feat for PC players, modders once again proving their love and dedication for the game, I respect it. Now to find 3 ppl to join in with me....

If anyone also has this question, yes it works with 360 control

this mod is the best mod to have come out for a Halo game yet. looking forward to the controller remap for splitscreen players, I would love to change some controls. but at this point i cant complain as they have alot of different default ones that works really well.

Thank you so fucking much. I have been holding onto my xbox just for splitscreen. I don't feel tethered anymore. Thank you thank you thank you!

Here, have a sub for this!

AWESOME!!!!!

This is the thing we needed added into all Halo games including Halo CEA and 2A campaigns (for up to 4 players!)!

Heck yeah 4 player coop finally

Thanks for sharing.

Sir this is very relevant to my interests.

you are a LEGEND

Really cool even though I don’t have extra controllers! The only issues I’ve witnessed from the little time I’ve spent with this is that my game audio goes silent and my customization goes back to default. But it’s real cool that this exists either way!

Currently weeping with joy

Amazing! Thanks a lot.

It's finally fucking here!!! Something i wished we could have for almost a decade now

Thank you so much!

So exciting!! Thanks for helping with this mod and sharing the news :) I wish 343 can spare some manpower to look at the coding on this and maybe add it officially. Would love to play matchmaking with it!

Amazing work, I'd be curious if multi monitors is possible to support? And possibly, having different sound sources for each player...

is good to see another Metroid fan, we finally got brief Metroid Prime 4 gameplay/footage

So annoying that 343 just doesnt care about split screen. At least the modding community cares.

Nucleus Co-op mentioned 🥳

LEGIT: I gotta test this

That's amazing ! I think the only way to mak it better would be to be able to use a second screen for the second player. Maybe one day !

you are my messiah. I was absolutely crushed when I found out this wasn't a built in feature

IT'S ABOUT FUCKING TIME!

You can also play Halo 1 and 2 coop in 4 player mod which is new

this is amazing man, thanks. also any possibility of it being added to the steam workshop?

To all involved, *Great work!* 👍 I’m excited to see this in action on the Steam Deck as that’s our main party machine. And now I'm dying hoping Left 4 Dead gets this sort of treatment. 💙💜🔥

This is amazing, thank WinterSquire and Priception so much for this, looks like a dream come true. o:! Hope we can get option to edit players 2-4 controls, but if not, oh well ¯\_(ツ)_/¯, thank you regadless :)

I just used this at a LAN party with a group of friends and we had some overall positive experience with it. But did have some problems. We stuck mostly with halo CE. We had a mix of devices. Steam decks, ROG ALLYs, Xbox, PCs with this mod installed. On the PCs, it absolutely worked and allowed us to split screen just fine. What we had trouble with was trying to assign people to a team. Say for example four people are doing split screen but we wanted to have everyone on one display be on the same team. There would be no way to force all players on the same screen to be on the same team and often times there would be at least one person on the opposite team on one display. User error is a possibility, but I couldn't find anything meaningful about it in my search.

how do I set up the controllers between player 1 and player 2 and if the other wanted inverted controls too?

This is absolutely amazing!! I have a technical question that may be helpful for those with multiple screens (including myself), is it possible to force the splitscreen 'split' to be vertical instead of horisontal? I would imagine that this would be much harder (if even possible at all) due to being a new feature instead of just re-enabling an existing feature, but if it is possible that would be incredible!!

Awesome

Hi when I launch Halo MCC on steam after installing the mod, I can't actually see the game, but I can hear the music. When I try clicking on the game at the bottom of the taskbar I still cant see the game, just my wallpaper. I was wondering If there a way to fix this?

Holy shit

you only joked about Nucleus Co-op being bad but in my attempt to set it up, even getting its somewhat confusing configuration seemingly right, the multiple-views-in-one-monitor setup didn't work, and this was before I learned each game is entirely its own application instance and every single one needs its own Microsoft account to play. I find even one of those is too many but keep it in use out of necessity, even with burner emails I have no intention of making anymore. I only wish this let you customize controls because the folks I want to play locally with like having controls different from the default, then this would be an absolute godsend.

Is there any way to change the FOV? its kinda hard to see enemies that are far away with my tv( playing on steamdeck)

I'm having issues with getting my controllers to work when I'm in split screen mod. Any idea how to get this to work? When I'm in split screen mode and I'm moving around with my main controller, I see my pointer cursor moving along the screen. I don't have any issues with my controller if I'm just playing solo

Cheers

This is amazing! Is there a way to invert look settings for each controller/player? I only play with inverted looks and even if I am getting split screen its unplayable for me..

Is there any way to flip the split screen vertically so I can use both monitors for me and my brother to have a full screen each

absolutely shameful that developers just gut split screen from their pc releases, this is awesome thank you so much for showcasing it, looking forward to your mod tutorials.

I noticed other people losing audio once the level starts, I am having the same issue. Anyone find a fix?

@Priception im having a issue where the game freezes at the end of a leave while playing co-op halo ce. Toggling the alpharing menu dosent seem to work. Any ideas would be greatly appreciated. Its not the end of the world just a little annoying.

Hey, I'm having an issue (and have a workaround for it!) when i select 2 player split screen and enter the game, when i use the left trigger on one of the controllers, it will change the graphics, throw a grenade, and freeze the game at the same time. with the other controller, i can pause and unpause and the game will resume. This happens every time. i've tried: restarting steam/disabling steam input/changing steam input layouts/rebooting my PC. updating controller firmware (they are both Series X controllers, using bluetooth, and they were already on the most recent firmware) it happened to either controller, player 1 or player 2, which i think rules out a hardware problem. I did find that, after loading a level in 2 player split screen, i went back into the menu and turned on a 3rd set to any input that isn't the one freezing the game (or none), the left trigger on the affected controller stopped having this issue! another thing is the split screen interface doesn't disable inputs or pause the game like it says it does for me.

Sweet buttery biscuits, thank you so much!! This is what me and my brother have been waiting for, some good ol coop action with friends in the same place! Thanks for keeping the local coop experience alive. It means a lot man. 🫡 🎉

Hey so the mod works great, it’s just when I spawn in, the keyboard player’s character keeps looking up and rapidly spinning, and I haven’t found a way to fix it, has anyone else had this issue?

How do i customise the other players

Holy smokes, Batman! No longer will I have to wait for Xemu to patch up for Halo 2 seeing through the floors or Xenia to patch up for smoother Halo 3 play on my deck.

Hey the menu is sill not showing up even when I installed Microsoft Visual C++, how do ifix this?

Would steams controller remapping work then if the mod can't atm?

How do you get Microsoft Visual C++ to work on steam deck. It's an .exe file & doesn't install. The spiltscreen pop up doesn't appear in MCC eventho I followed all instructions.

Is there a way to switch teams in multiplayer? Can't seems to change teams so it always ends up X vs 1

Thank you so much! This is just amazing! I have been getting lots of artifacts on Reach when playing split screen, specially when I aim down my sights, any recommendations?

Hello, I have a graphic problem with my RX 580. Specifically with Halo Reach, the models look of poor quality and with white lighting. Any idea what it could be? The problem happens when there are two players, when there are 4 there is no problem, when there are 3 players the one above has that problem.

I download the mod interface and mod itself but when i open the game I don't see it :(

Holy molly

I installed this mod and then the sound wouldn’t work when I actually went to play Halo 1 coop. Everything set up correctly. The game menu still had sound when paused, but actual gameplay sound is off

This is amazing work, thank you. I have 1 question, are you able to customize the other three player's armor in MP?

Love Nucleus as much as the next guy but native support is even better!

Okay I’m on steam deck and did all of this and it’s not showing up… do I need to download the VC distributable?

When playing split screen is there anyway to get rid of the black borders? I'd like to have the entire screen filled and not have these black borders.

can you split the screens to 2 different monitors?

I just get stuck in the death screen while loading up the game and can't do anything

Since it’s with anticheat off, it probably wouldn’t count my campaign progress would it? I’ve been trying to play laso with my brother and I want it to count.

can you change the aim speed of the 2nd player?

Hey friend, I have a question, how do I play online with this mod or is it impossible? I mention it because in order to play with the mod you have to start without the antichest so I try and it won't let me play online this way only locally

I NEED HELP. I followed the steps one to one but in halo reach player ones screen is glitched the best way i can describe it is the shaders are broken

Is it possible to play split screen with two monitors and each person get a full monitor?

Can the other split screen players play on a different display

So all the games technically support 16 player co-op now via this mod? Based.

What’s the toggle for the menu?

Does anyone know how you can add a controller/player? I got the three screens up but none of them have any controller input

Another question, sorry to be able to play online games again, how do I do it?

Can i use this mod on the microsoft xbox whatever launcher as well because i bought it there this would be really nice
