Going Medieval This is an upcoming Steam Early Access game that blends city-building with colony survival mechanics, offering a medieval mash-up of Rimworld and Dwarf Fortress ethos. You’re in charge of a struggling Dark Age settlement, emerging from the ashes of a plague that wiped out most of the population. You must build up your fortress and expand out into the wilderness to forge a better future for your people. It’s already looking like an interesting take on the idea, although you’ll have to wait until June 1 to get your hands on it. One final beta will be available for people to try later this month before it hits Steam.
