MachineParty+ is an all-in-one community mod for Machine Party. It adds a global server browser, voice chat, text chat, player moderation (kick / ban), a live in-match scoreboard, and full translations into every language the game ships with, plus Arabic.
Everything is built on top of the game's own Steam networking and is styled with the game's own fonts and a green terminal theme, so it fits right in. It does not repack or modify the game's data files. It only adds to them.

- Server browser — a worldwide, non region-locked list of public lobbies, in place of the main-menu JOIN button.
- Host a public lobby — a "Make Lobby Public" toggle (private by default), with a popup to name your lobby, set a max player count (up to 4), and choose whether people can join mid-match.
- Join by room code — paste the game's normal 18-digit room ID to join a private lobby directly.
- Voice chat — proximity-free party voice built on Steam P2P, with mute, deafen, and per-player volume, plus a device picker (choose your mic and speakers) that saves between sessions.
- Text chat — a lightweight chat box (press T) with a smart profanity filter, per-player mute, and join / leave notices.
- Manage Players — mute or set the volume of anyone in the lobby. Hosts also get Kick and Ban (with a confirmation prompt).
- Banned Users — a persistent, Steam-ID-based ban list. Banned players are auto-removed and cannot see or rejoin your lobbies until you unban them.
- Mutation scoreboard — hold Tab during a match to see everyone's live mutation score and how many rounds they've won and lost.
- Translations — the whole mod UI follows the game's language setting. Every game language is supported, plus Arabic, with more polish and languages to come.
MachineParty+ is a pure GDScript mod loaded through the Machine Party Mod Loader.
Machine Party already runs on Steam lobbies, but every lobby the base game creates is friends-only, so lobbies never show up in a public search. MachineParty+ changes that in a safe, additive way:
- When you make your lobby public, the mod flips your existing Steam lobby to a public type and tags it with a little lobby data (name, max players, game version, host name). Turning it private again restores the friends-only default.
- The browser asks Steam for a worldwide list of lobbies carrying that public tag and reads each one's data to show its name and player count.
- Joining a lobby reuses the game's own client join flow, the exact same path used when you accept a Steam invite. Nothing about the underlying connection changes.
- Voice and text chat, kick/ban messages, and moderation all ride on Steam's peer-to-peer messaging alongside the game's own networking.
MachineParty+ is fully cross-compatible with players who do not have the mod. You do not both need it installed to play together.
- If you host with the mod active, you can still give your room ID code to a vanilla player and they can join and play with you completely normally.
- It works the same the other way around: with the mod, you can paste a vanilla host's room ID code and join their game just fine.
- Public lobbies only appear in the browser for people who also have the mod, but anyone can still join by room ID code.
The only difference for mod players is that the in-game Invite button does not work (a Steam overlay limitation of the mod loader), so mod players just share the room ID code instead. Voice and text chat only reach other players who also have the mod.
MachineParty+ adds its own buttons around the game. Because the game only has room for so many buttons at once, some of them move depending on where you are (main menu, in the lobby, or in a match). Here is exactly where everything lives.
- JOIN opens the server browser.
- Two extra buttons are added to the menu in the game's own style (circled above):
- Voice Settings — pick your microphone and speakers. Your choice is saved and reapplied every launch, so you only set it once.
- Banned Users — view and manage your ban list.
Voice Settings and Banned Users panels:
- A live list of public lobbies from around the world, each showing the lobby name and current players out of the max.
- REFRESH (top right) re-fetches the list at any time.
- A lobby's JOIN button joins it. Full or version-mismatched lobbies are shown but can't be joined.
- ROOM ID field (bottom): paste an 18-digit room code and press JOIN to join a private lobby directly. PASTE fills the field from your clipboard.
- ✕ (top left) closes the browser.
Make Lobby Public (host only). In the lobby's normal button row you get a MAKE LOBBY PUBLIC button in the game's native style. Press it to open the setup popup:
- Type a lobby name.
- Set max players with the up/down arrows (capped at 4).
- Toggle Allow mid joining — when on, your lobby stays listed after the match starts; when off, it drops off the browser once the match begins or the lobby is full, and reappears when a slot opens.
- CONFIRM publishes it. The same button now reads MAKE LOBBY PRIVATE, so pressing it again flips you back to private. It is a simple on/off switch.
Side buttons. A small strip on the left of the lobby screen, styled to match the game's buttons (just a little smaller so it tucks out of the way):
- MANAGE PLAYERS — available to everyone. Opens a live list of players where you can mute anyone or set their per-player volume with a slider. Hosts get an extra MANAGE button on each player for Kick / Ban.
- BANNED USERS — host only. Opens your ban list to review or unban (same panel shown in the main-menu section above).
Voice mute / deafen. Two buttons float in the top-right corner while you're in the lobby:
- MUTE MIC — others can't hear you; you still hear them.
- DEAFEN — you hear no one and no one hears you.
They hide automatically whenever a menu or popup is open.
To keep the play area clean, the lobby's extra buttons move into the pause (Esc) menu once a match starts. Press Esc and you'll find Manage Players (everyone), Banned Users (host), Mute Mic, and Deafen added to the pause menu in its native style:
The floating mute/deafen and the side strip disappear during gameplay, because they now live here in the Esc menu.
- Hold Tab during a match to bring up the scoreboard: every player, their live mutation score, and how many rounds they've won and lost.
- It never grabs your mouse, so you keep playing normally while it's up. Mid-game joiners are added, players who leave drop off, and rejoiners keep the score they left with (just like the base game).
- Open Manage Players (host), press MANAGE on a player, and choose KICK or BAN.
- A confirmation prompt appears first so you never remove someone by accident.
- Kick removes them from the current lobby (they can rejoin).
- Ban removes them and blocks them from seeing or rejoining any lobby you host, until you unban them from Banned Users.
- Press T in the lobby or a match to open chat. Type a message and press Enter to send, Esc to cancel.
- A smart profanity filter (local only, toggleable in the chat options) censors slurs and swearing, including padded and misspelled variants.
- You can mute individual players in chat, and joins / leaves are announced.
- The entire mod UI, server browser and chat included, follows whatever language you set in Machine Party's own options. Change the game's language and MachineParty+ changes with it.
- Every language the game ships with is supported, plus Arabic (added by this mod, selectable right in the game's own language list). These are community translations, so more polish and additional coverage will come over time.
A step-by-step walkthrough of installing the mod loader and MachineParty+, start to finish:

🇪🇸 ▶ ¿Lo prefieres en español? Mira la guía en vídeo
MachineParty+ runs through the Machine Party Mod Loader by Krunk-theduck. You install the loader once, then drop MachineParty+ into the mods folder. Everyone who wants to browse, host, use voice/text chat, or moderate needs both. A friend can still join your private lobby by room ID code without either.
- Find your game folder. In Steam, right-click Machine Party in your library, choose Manage, then Browse local files. Open the
Machine Party_Windowsfolder. It containsMachine Party.exeandMachine Party.pck. - Download the loader. Get
MachinePartyModLoader.exefrom the loader's releases page (extract it first if it comes as a.zip): https://github.com/Krunk-theduck/MachinePartyModLoader/releases - Place the loader. Drag
MachinePartyModLoader.exeinto that game folder so it sits right next toMachine Party.exeandMachine Party.pck. - Run it. Double-click
MachinePartyModLoader.exe. If Windows shows a security warning, click More info then Run anyway. A command window shows the setup progress and closes when it's done. This creates amodsfolder in your game directory.
- Download
Jarunk-MachinePartyPlus.zipfrom this repo's releases page: https://github.com/Ghostx10742/MachineParty-Plus/releases - Extract it into the
modsfolder inside your game folder, so you end up with the folder (not a zip) at:That folder should contain<your Machine Party folder>\mods\Jarunk-MachinePartyPlus\main.gd,mod.json, and the other mod files.
- Start Machine Party from Steam exactly like you always have. The mod loader hooks in automatically, so there's no special shortcut.
- To check the loader is active, press the backtick key
`in-game. A small debug console appears if it's working. - On the main menu, press JOIN to open the server browser. To host a public game, start a lobby and press MAKE LOBBY PUBLIC.
To uninstall, delete the Jarunk-MachinePartyPlus folder from mods. To play vanilla again, remove the loader (or just delete the mod folder).
MachineParty+ runs on top of the Machine Party Mod Loader, so a future Machine Party update can temporarily break the loader (and with it, this mod). If that happens, mods may stop loading.
If it does, don't panic and don't keep reinstalling. Wait until the mod loader pushes an update that fixes it, then update the loader and launch again. Your normal, unmodded game is never affected.
MachineParty+ is pure GDScript, so there is no compile step. The Machine Party Mod Loader loads mods as loose folders, so "building" just means zipping the mod folder for release, so that extracting it into mods gives you mods/Jarunk-MachinePartyPlus/.
Requirements: git, and Python 3 (used only to package the zip).
- Clone the repo:
git clone https://github.com/Ghostx10742/MachineParty-Plus.git cd MachineParty-Plus - Build the release zip:
This writes
python build.py
dist/Jarunk-MachinePartyPlus.zip. - Install it for testing: extract the zip into your game's
modsfolder (so you getmods/Jarunk-MachinePartyPlus/), then launch Machine Party normally from Steam.
Dev loop: edit the GDScript in Jarunk-MachinePartyPlus/, copy the folder into the game's mods folder (or re-run build.py and extract), and relaunch.
