More than 4 player coop (game modification) [PATCHED]

Overview

I ran in to a small problem. I have more than 3 friends that play phasmophobia. So when i modified the game i was able to play with all my mates. Let me show you how to install it: (this mod allowes for a max of 8 players to join)for contact and or if you are the developer (and want me to delete this post) please send me an email to the address belowLet me know if you have any issues in the comments.

Intro

Yes you might have googled on how to play phasmophobia with more than 4 players. Well i didnt do so… So i started to go to work and change the game a bit.

After i made the modification i started to google who had already made such a modification, (this was because i noticed a couple lobbies with more than 4 players). After finding someone else’s project on github i was able to see what they made their mod do. I personally wasn’t really a fan of it. Their mod changed the core of the game (by being able to add more ghost’s, change your name & colour, hunting delays etc.) This is quite funny ofcourse, but that defeats the spooky purpose of this game.

My mod is basically vanilla + 8 players and no cheats 😉 With more then 8 players the game becomes unstable and no fun anymore. i wouldnt even recconmend more then 6 tbh.

it was quite easy to mod, like any other unity game. Thank you developer for using photon! like i do in my games. (if i ever finish one that is lol)

Let’s start

Let’s go and start hunting ghost with all of your mates. Phasmophobia is still in development and will receive more updates. So lets first check if you have the same version as the modified file.
For this start phasmophobia. in the main menu you should see a server version on the bottem-left

this version should be 0.174 like shown in the picture:

if all is good then you may go to through with the installation process. just make sure you dont install the mod if your version differates from the one in the picture (0.174). Ill update the guide when the game updates.

Please also note that the loading time increases when starting the game with more then 4 players. Please be patient, even though your game looks like it’s not responding.

Installation & download link

Installing the mod is really simple. so lets go!

note: if you messed up your game install then just click “verify the integrity of the game”.

note: i also added the one that comes with the game, just so you have an second backup.

download link:
[link]

dont worries, the download button looks like a scam lol. I’ll get that changed soon

You will have to extract “phasmomod.rar” with winrar/7zip or any other archiving software.

then extract the contents to the folder i mentioned above (“..Phasmophobia_DataManaged”)

Starting a lobby and checking if it works

You can find a sign on the main menu showing you that the mod works. This is a simple text next to the server version. This also works as a reminder you still have the mod installed.

Please don’t try to join 4 player lobbys that arent modded and full. It wont work..
It might show like there is place for 8 players, but the server will decide that you are not allowed to join.

this is just to prevent your game from crashing, this was the only bug i could find that would crash the game

What also could happen is that the lobby screen glitches (visually), so again first set everything up (items,map) and then invite your friends.

Kicking players is laggy. the board only has place for 4 entitys so kicking player 5 is close to impossible…

the ready and start buttons are a bit bugged. They should still work

Outro

Ok so we had allot of fun playing phasmophobia. But if you have any questions and or complaints send me a mail at

[email protected]

if you are the developer and very mad that i made this mod then send me a mail at:

[email protected]

(filtered whitelisted-wildcard so you can decide what my email address is today ;))

Ok so the core of the game is not designed for more then 4 playes. some things work better then others.

a funny glitch is that you can make a picture of one of your friends (that is not fully registered to the game) and it will become evidence as a dead body.

I tried to change the lobby to add more items, but after that try the item spawner pooped it’s pants. I dont want to change everything to make that work correctly. It’s not my game and i already think it’s not very nice of me for releasing this mod.

i didnt put allot of work in this mod, there are allot more talented modders then me so keep your eyes out for other options 🙂

I hope we will soon see more updates of this great game! And (maybe) even upping the players size for asylum. Since that map is great to play with 6 gamers ;).

My friend contacted the developer via discord and this was his response:

My friend didnt ask anything about sharing it. I will contact him too. Probably going to be a bit hard since his inbox is pretty full i guess…

Updates

A new post appeared on the discord server of Phasmophobia:

Immusama – Today at 6:18 PM
@everyone
Info – #rules – 6. Hacking & Piracy:

We are aware that there has been a number of games that have been using third party tools (cheats) to modify the game.
This includes changes such as increasing player limits, changing AI behaviour and simply increasing money or level.
We cannot support this as it is causing a number of issues across the game, including the corruption of saved games and destabilizing the servers for other players.

We strongly advise you to not join any of these games as they can harm your save or game files, as well as disrupt the game for others.

The easiest way to determine if a lobby is a “modded” is, if it has more than 4 players. Other signs can also be unusual AI behaviour, teleporting, or even multiple ghosts.
Some of these users have been claiming to be developers with access to tools. No member of staff will be using such tools in the public branch of the game and all testing is done on private beta and developer branches.
Anyone using such cheats are not developers or members of staff.

We are currently looking into ways to combat this but until then please avoid joining such games so your files are not corrupted and the servers can function normally!
Thank you

Im just sharing the information, to give you an indication. Please note that savegame corruptions mainly happens when save-game information is being edited. My mod only changes the way the server and (clients) work.

Im still waiting for a reply from the developer, as it is not my intention to ruin anything. The only reason i made this mod was that my 5 friends can play this game with me on the bigger maps.

And i wanted to share it with others who walk against this limitation…

Here is a repo with the binaries and the changes i have made:
so you can do it yourself 😉

github link [github.com]

I can’t get the mod to work on the beta version (IL2CPP). Soon the game will update to IL2CPP, that’s the day this mod won’t work anymore. it crashes the game and or doesnt let more then 5 players join. Im going to keep an eye out for if someone else manages to make it work. But for now im not going to put any more time/work in it. When i find anything working and usefull Ill share the link here.

the changes i made are available here: [link] (MONO)

so you can see what a low effort mod this actually was. Never knew it would take off like that. 20k registered downloads is quite much.

And the archived project for the IL2CPP mod that i abandoned (i removed all the harmony patching & handling code because it didnt work, same goes for the 8 playermod itself. No point in uploading something that doesn’t work…)

It only contains the discord rich presence code lol.
