Multiplayer in GRAIN ROT

Launch build · checked 2026-08-12 · Last checked 2026-08-12

System overview

GRAIN ROT uses player-hosted Steam lobbies, supports solo, has no public matchmaking, and is balanced around roughly four players without a fixed hard cap.

How It Works

Multiplayer starts from a Steam lobby rather than a public queue. The host creates the session and friends join through Steam, which keeps the joining flow tied to the player’s existing friends list.

Hosting and Joining

Use the Invite Friends answer for the confirmed lobby path and its limited troubleshooting scope. It does not add NAT, port, or public-matchmaking instructions that are not supported by the evidence card.

Group Size

The game is balanced around roughly four players, but official guidance does not name a fixed hard cap. Hardware and host conditions matter; a reported six-player session is a possibility report, not a promise.

Solo Expectations

Solo is supported, but it changes the recovery margin of a run. Use the Solo answer for the official balance context instead of treating multiplayer and solo as interchangeable difficulty modes.
