Stardew Valley [/I]now supports online multiplayer.
Update 1.3 has slowly but surely made the rounds across PC, PlayStation 4, and Nintendo Switch. After a few false starts with certification, Xbox One players
can try four-player co-op too. If this is your first time playing Stardew Valley with friends, you're in for a treat – you can even use emotes!

There's also new content in 1.3, including a winter Night Market (on the 15th, 16th, and 17th, starting at 5:00pm near the ocean docks) and the Auto-Grabber, a tool to help you harvest milk and wool.
As for update 1.4 – the one that "touches pretty much every aspect of the game in some way or another" – it's coming soon to PC. "Just finishing up a few final things," said designer Eric Barone.
"It's very close."
