Klei Entertainment stressed its new footage of Don't Starve's mulitplayer expansion is of a "very early prototype," and everything in it is subject to change. It does, though, provide a look at the ghost mechanic in place for when players die in Don't Starve Together.
The video shows one player bludgeoning another, with the poor victim turning into a ghost as a result. The ghost player can then float around and haunt stuff - with varied results - before reviving by haunting a meat effigy.
In a detailed deconstruction of the playtest that provided the footage, Klei's Seth Rosen discussed how he's trying to deal with what he called "ghost-griefing." The way the playtest was programmed, it was a bit too easy and predictable for players to haunt objects and set them on fire, which doesn't make for the most helpful of ethereal companions.
"It's important for us to bear in mind that, even though we don't want to encourage people to play like this, we do want to allow for it," Rosen wrote. "It shouldn't be appealing or easy, but it should be possible. Functionally, this means making the bad effects of haunting into something you're surprised by, not something you're expecting."
At the moment the multiplayer expansion is only confirmed for Windows PC, Mac and Linux, though Klei would like to bring it to PS4 if possible. It'll be a free addition for current players, but it'll otherwise raise the game's price by 5 bucks to $20.
