Welcome to Stardew Valley! Here are some common answers to get you started. Feel free to ask questions here. :)
When will multiplayer be released for my platform?
Stardew Valley 1.3 (multiplayer) is live on all current platforms. There are no current plans to implement multiplayer on Android/iOS, though they'll otherwise be kept up-to-date with PC content.
Please don't ask for time estimates, because we don't know either! It's hard to predict because multiplayer is complex and each platform is different. An update might go smoothly, or it might require months of bugfixing and polishing. Here are the latest updates for each platform:
Stardew Valley 1.3 is now available on Xbox! Feel free to ask here if you have questions about the update.
Does the game have split-screen?
Nope. It may never be supported, due to the technical difficulties of rewriting the game code to support it.
Does the game have crossplay (crossplatform multiplayer)?
Nope. ConcernedApe wants to look into it in the future though.
Do item spawn codes still work?
Nope. That was patched on consoles in 1.3 due to certification requirements from Microsoft/Nintendo/Sony. It still works on PC, which doesn't need external certification.
How do I pause the game in multiplayer?
Nope. The host player can pause the game anytime by pressing the right stick, pressing X to bring up the keyboard for in-game chat, and entering
/pause. To resume, go to the chat again and enter
/resume. After you do it once, the game will suggest the commands after you type
/ to make pausing faster.
