At the International Dota 2 Championships this year, Valve surprised with the announcement of a new title. Artifact is a digital collectible card game, like Hearthstone and Gwent, but with Dota-related art. Valve offered up a short teaser trailer for the title and a release window in 2018.
Brad Muir, the former Double Fine designer behind Massive Chalice and Iron Brigade, is involved in the development of Artifact. According to descriptions given by broadcaster Sean "Day9" Plott, Artifact will involve classic Dota staples like lanes, creeps, and barracks.
We'll have more on Artifact when Valve offers more details on the title.
