Machine Party Max Players: 4 and 8-Player Mod Status
LIMITED OFFICIAL DETAIL
DIRECT ANSWER
Machine Party officially supports 2–4 players. A community 8 Player Mod now targets v2.1.2 and reports automated eight-client tests, but its still-open testing issue records that a real 5–8-player Steam session was not properly verified. Treat current human-session compatibility and safety as pending, not official support.

This frame shows Machine Party’s group-play context; Steam’s written listing supplies the official 2–4 range. It does not verify an unofficial mod or a 5–8-player session.

2–4 PLAYERS
Steam lists Machine Party as a 2–4-player game.
The official listing documents two through four players and does not list a fifth seat.

What the current Mod pages actually establish
MachineParty+ v2.1.0 is described by its authors as updated for Machine Party v2, but its own player-limit setting still caps lobbies at four. It adds online lobby and communication tools, not a fifth seat.
A separate 8 Player Mod v1.5 now claims a 5–8-player online cap for Machine Party v2.1.2 and reports automated tests with eight clients. Its still-open testing issue says a real Steam 5–8-player playgroup test was not properly verified. This guide preserves that gap instead of turning an author report into independent proof.
- MachineParty+ v2.1.0 — author claims v2 support; maximum remains four players.
- 8 Player Mod v1.5 — author targets game v2.1.2; real 5–8-player Steam play remains pending.
What a five-person group can do now
For a dependable session, keep each active match within the official 2–4-player range and rotate the extra person between short sets. Arcade mode is built around 10 random simulations, which gives a larger group a clear handoff point without relying on an unverified build patch.
This page does not provide a download or installation recommendation for the experimental project. A public release page proves that a project exists; it does not prove current compatibility, stability, or download safety.
- Online group of 2–4 — use the normal online flow.
- Local group of 2–4 — use v2.0 Local mode; the couch guide has the confirmed setup steps.
- Group of 5+ — rotate for a dependable session, or treat the matching community Mod release as an unofficial experiment.
- Need strangers — use the separate matchmaking guide; the developer says there is no in-game public lobby list.
