"We hope all gamers enjoy Artifact, especially fans of Dota 2 and card gaming enthusiasts," Valve boss Gabe Newell said. "Working with Richard Garfield has been an incredible opportunity for everyone at Valve, and we look forward to expanding the game with him based upon feedback and input from the community."
Call to Arms follows Prelude, released earlier this week, which introduced players to the House of the Cunning, whose members wield powerful magic that can change the course of history. And while barebones narrative frameworks are pretty much mandatory for digital card games these days, this tale promises more: Valve said that Call to Arms "sets the stage for a series of events that will transform the world of Dota," the setting that Artifact shares with with mega-MOBA Dota 2.
"Working on Artifact has been fantastic—a digital card game which really leverages what is made possible by the medium rather than being limited by it," said Garfield, whose previous game creations include Magic: The Gathering. "That has been a long time dream of mine and Valve has been a terrific partner in the development."
Artifact is available now on Steam for $20, and the Artifact Marketplace, where players can buy and sell cards, is now open as well. (It initially appeared to have only Common and Uncommon cards listed, but Rares are now available as well.)
