During PC Gamer's show at E3 2018, a trailer was shown for Don't Starve: Hamlet.
In this singleplayer DLC for Don't Starve, player-character Wilson, amidst a jungle, finds a lost town of aristocratic pig people. There's a pig marketplace, pig homes, and, speaking to some history, ancient pig ruins. These will hold a new gameplay feature: treasure hunting for players to try out.
It's coming December 2018 to PC, Max, and Linux, on Steam.
