The highly anticipated multiplayer update for Stardew Valley has been in beta for some time now, but it's about to make its debut on PC sooner than you might think. Rebuild your grandfather's farm with a little help from your friends starting August 1.

Stardew's multiplayer is all about working together. You and up to three other players can create the farm of your dreams, or duke it out with some monsters. Just make sure that when your friends come to visit, they have a cabin to call home.
