Machine Party max players: online and local limits
This is the canonical player-count page: it owns the confirmed online and Local limits and separates supported counts from unverified claims beyond four.
Machine Party supports a 2–4 player online room. Since v2.0, Local mode also supports up to four players on one PC, using up to four controllers or three controllers plus keyboard and mouse.
Machine Party player limits at a glance
Use the confirmed online and local counts for a party today. Treat modded counts as unconfirmed until official notes say otherwise.
| Mode | Maximum | What is confirmed |
|---|---|---|
| Online private room | 4 players | The current Steam listing describes a 2–4 player session. |
| Native local / couch co-op | 4 players | v2.0 supports up to four controllers, or three controllers plus one keyboard-and-mouse player. |
| Community mods | No supported expansion | No official mod or player-count extension is documented. Unofficial tools may break saves, networking, or anti-cheat expectations. |
Online
How many players can join a Machine Party room?
Plan for two to four players in a private online room. A fifth player cannot be treated as supported by the current listing; use voice chat or a stream for anyone watching from outside the lobby. The multiplayer guide explains room IDs and Steam invites.
Local play
How many players can play on one PC?
Up to four. In v2.0, open Local and choose Original, Custom, or Arcade. Connect up to four controllers, or use three controllers plus keyboard and mouse for a group of four. Screen behavior varies by simulation, so four players does not always mean a fixed four-way split screen.
See the local co-op and split-screen guide for the exact menu flow and the documented simulation layouts.
Beyond four
Can five or more players join, or can a mod expand the cap?
There is no supported mod that expands the player cap. A community experiment may exist later, but an unofficial player-count patch would need to change lobby, networking, and minigame logic together. Until the developers document a supported extension, treat any “5-player” or “8-player” claim as unverified and avoid using it in a live account or save.
Player counts are based on the official Steam listing and launch-build multiplayer documentation. Local co-op and mod support are time-sensitive; this page will be revised when official details change.
