Local co-op & split screen

Official statement

What the developers announced

In the launch-day Steam announcement, the developers said Machine Party would not launch with local co-op. They also said local co-op would be added in an update in late August after additional stability work. This is an announced target rather than proof that the patch is already available.

Until patch notes explicitly say the feature has shipped, do not assume that connecting several controllers creates several subjects. The Steam store’s full controller support describes controller input for the game; it does not by itself confirm same-PC multiplayer.

Split-screen question

Will it use split screen?

The announcement uses “local co-op” but does not document whether every trial will use split screen, a shared camera, alternating views, or a mixture. Machine Party’s minigames use different perspectives, so the final presentation could vary by trial. Any specific layout claim before the update is speculation.

Buying decision

Should couch groups wait?

If your group owns one PC and local play is the only way you intend to play, waiting for the update and current player reports is the safer choice. If two to four people can each join through Steam online, the launch build already supports that session model.

Do not buy extra controllers specifically for four-player local play until the patch notes identify the supported device count and setup. The game supports two to four players overall, but that total currently describes the online session.

Remote streaming

Is Remote Play Together a substitute?

Remote streaming may be experimented with, but it is not equivalent to confirmed native local support. Input ownership, latency, per-player device detection, and minigame-specific controls can make the experience unreliable. Treat it as an unsupported experiment until Steam or the developer advertises it for Machine Party.
