Don’t Starve Together is local split screen. Cult of the Lamb is local coop without split screen. The dungeons are divided in rooms and split screen isn’t necessary. It just zooms out enough that you’re both on screen. Except in camp. There you need to stay somewhat together or you go off screen.
Ah, that could be it. I played Don’t Starve on PS4, but Cult I bought on Steam. I know for sure that Cult has local coop.
