Quick Answer
Machine Party does not have Steam Workshop support, and the developers have not announced official mod support. What exists is a small community ecosystem built around one community-made mod loader, with three projects that most players talk about.
A few non-negotiables about this ecosystem before you read further:
- There is no Valve-blessed way to install mods. Everything is community-run, invasive, and outside the official Steam workshop infrastructure.
- The mod loader works by rewriting game files. It's not a sandboxed plugin system — it's an in-place modification.
- The developers have never said whether mods are allowed, banned, or supported. Don't take anyone's word — official or unofficial — on safety, ban risk, or compatibility. We don't either.
We name the projects so you know what to look for, but we don't link to any download pages, project homepages or Discord servers in this article. Find them yourself if you decide to proceed.
No Official Mod Support
The Steam store page, the store category list, and all eight official announcements since the game's reveal in April 2026 agree on one thing: no mod support, no Workshop, no policy.
- The Steam category list does not include Workshop.
- The store description doesn't mention mods.
- No announcement has addressed the topic of mods, modding, or third-party modifications.
The developers' stance on community requests generally has been firm: in the v1.5 announcement on August 4, 2026, they explained that public matchmaking was requested but won't be added because it conflicts with the original vision. Mods occupy a similar space — the developers don't endorse them and don't condemn them; they just don't talk about them.
This is the "official silence" you should assume when reading anything about Machine Party mods.
The Mods That Exist
Three community projects do most of the talking in the Steam discussion threads:
- Machine Party Mod Loader — by Krunk-theduck. The base loader. Sets up a mods folder, hooks the game to load scripts from it, and includes an uninstall path. Also ships a small example console mod.
- MachineParty+ (MP+) — by Ghostx10742. Built on top of the mod loader. Adds a global server browser, in-game text and voice chat, kick and ban controls, a scoreboard, and a few extras.
- MachinePartyFPV — by Krunk-theduck. Adds first-person camera views, kill cinematics, a lobby camera, a settings menu, and controller support to simulations that originally didn't have them.
There are also smaller or older projects — a separate Godot mod-loader variant maintained by a different group, and a handful of one-off mods. We don't enumerate them all here because the scene changes often and this page can't keep up with the full list. The Steam discussion board's mod-themed threads are the most current source for "what's out there."
How They Actually Work
The mod loader works by opening the game's compiled asset archive (.pck file — Godot's standard format) and injecting a small script that runs before the game's own code. That script then loads any .gd files placed in a mods folder.
This is significant for two reasons:
- It's an in-place modification. The loader rewrites a game file. If something goes wrong, you reinstall. If a game update ships a new
.pck— which is what happens every time the developers patch the game — the loader's injection is overwritten and has to be reinstalled. - It's an invasive trust model. You're running code written by a third party that modifies a file your game depends on. The project's own README states that the loader was almost entirely written with AI assistance and has not been audited. That's not a slam — it's just a statement of fact about how much human review this code has had.
The MP+ multiplayer mod is layered on top of the loader — it adds the actual gameplay-affecting features. The FPV mod is similarly a loadable script.
The Risks
These are the four risks that follow from how the mods work, stated as plainly as we can:
- The loader modifies game files in place. This is the inherent risk of any
.pck-rewriting approach. If a future game update changes the file structure in a way the loader doesn't expect, the loader breaks until it's updated to match. - Game updates can break mods. Every time the developers push a patch (the most recent being v2.0 on August 12, 2026 (UTC)), there's a real chance the loader needs to be reinstalled. MP+'s own README says exactly this: "a future Machine Party update can temporarily break the loader (and with it, this mod). If that happens, don't panic and don't keep reinstalling. Wait until the mod loader pushes an update that fixes it."
- The loader code has not been audited. The project's README states it was almost entirely written with AI assistance. We're not qualified to assess that code, and we haven't seen an independent security review of it. Treat that uncertainty as part of the risk.
- The developers have not said whether mods are allowed. No public statement from the developers or from Valve addresses whether installing these mods affects your Steam achievements, your online play, or your account status. We have no information either way. Don't take anyone else's word for it — including ours.
Will Mods Affect My Steam Account?
The honest answer is: nobody outside the studio can tell you with certainty.
There is no Valve policy that we know of that prohibits users from running third-party tools alongside Steam games, and there is no developer statement saying "mods are fine" or "mods will get you banned." Achievement unlocking could in theory be affected — Steam has the technical ability to detect modified game clients — but the developers haven't said whether they use that ability for Machine Party.
If the risk matters to you, the only safe position is to treat it as unknown.
