Quick Answer
Machine Party supports 2 to 4 players and has no solo mode. Every match needs at least two humans in the lobby — there are no bots, no AI opponents, no single-player mode, and no matchmaking system.
A few things have shifted with the v2.0 update on August 12, 2026 (UTC), even though the player cap itself didn't change:
- Couch co-op now lets four people play on a single PC with controllers, instead of everyone needing their own machine.
- The hardware cost dropped. A four-player couch group only needs three controllers, since one player can use keyboard and mouse.
- The "no matchmaking" gap is still real. The developers have explicitly said they will not add public matchmaking — they point players to the official Discord LFG channel instead.
The Cap: 2 to 4, Hard Limits on Both Ends
The player count comes straight from the official Steam store page: "Support for 2 - 4 players." It's the same number in every public-facing place — store page, store category list, all official announcements since launch.
Below 2 and above 4 are both out:
- Below 2 (single player): There's no solo mode, no bots, no AI opponents. The store category list doesn't include Single-player.
- Above 4: No announcements mention support for more. Players have asked in reviews and on the discussion board for 6–8 player matches; there's no official response to that request.
The official announcement language for the recommended setup is "grab 2 to 3 other friends" — meaning you plus 2–3 others, for a 3–4 player match.
What Couch Co-op Changed (and What It Didn't)
Before v2.0 on August 12, 2026 (UTC), a four-player game meant four machines, four game copies and four network connections. That's still an option, but it's no longer the only one.
With couch co-op:
- Up to four people can play on the same PC, sharing one screen or a split-screen view.
- Three controllers are enough for a four-player group — one player can use keyboard and mouse.
- Six of the 15 simulations were adjusted for split-screen and big-screen play. The rest behave the same online and on the couch. Full breakdown on the local co-op page.
The player cap (4) didn't move. What changed is what it costs to fill that cap.
What Two-Player Matches Actually Feel Like
This is the section where the evidence is thinnest, and we want to be honest about that.
- Two-player matches are technically supported. Nothing in the official documentation excludes them.
- Most player reports and YouTube content assume four players. Search the Steam discussion board for "two player" or "duo" and you'll find mostly general comments, not deep dives on 2-player balance.
- Player recommendations cluster around 3–4. The Steam comment thread most often cited is "make sure you have friends" — i.e., fill the lobby.
- No specific simulation has been called out as broken at 2. We did not find any reliable write-up that says "X simulation doesn't work at 2 players." That doesn't mean it's been confirmed to work well — just that nobody has published a test of it.
The honest summary: the game is built and balanced for four, two is playable, three is in the middle, and reliable 2-player balance write-ups basically don't exist yet. If you're considering a 2-player match, expect to discover the balance yourself.
Recommended Group Size
If you can pick your group size:
| Group size | What you'll get |
|---|---|
| 4 players | The intended setup. Most player reports, YouTube content and Steam achievements assume this count |
| 3 players | A common middle ground. Most simulations still work; the asymmetric ones (Inside Job, Duck Hunt) become simpler |
| 2 players | Playable, but the experience is lean compared to 4. If your only choice is 2, expect to make your own fun |
| 5+ players | Not supported. Don't try to push past 4 |
If you don't have a regular group, the official Discord LFG channel is where the developers point players who don't have friends to fill a lobby. The discussion board also has a steady stream of "join up and chill" threads with room codes.
If You're Below 4
Three honest paths, in order of effort:
- Find a fourth. Discord LFG or Steam discussion threads — fastest.
- Three players + bot? No. There are no bots. Three humans is the floor for "matches the intended design."
- Couch co-op with what you have. If your 2 or 3 people can be in the same room, you don't need a fourth — you just need the controllers and one PC.
