There’s one more Steam Next Fest event coming this year. The “multi-day celebration of upcoming games” will return again this October for dev livestreams and game demos for upcoming games on Steam.
The next Steam Next Fest for 2021 will be happening from October 1 to 7.
The previous Steam Next Fest, previously called Steam Game Festival, was held in June, with hundreds of limited-time game demos on offer.
