Valve announces its own Dota 2 card game coming in 2018: Artifact
However, we're not here to talk about Hearthstone, but about another game in the same gaming genre. Artifact is a new card game developed by Valve, owner of the Steam digital store and Dota franchise. The new title was announced during the online broadcast of The International, the $23 million Dota 2 tournament going on right now.
Aside from a short teaser that doesn't say anything about the gameplay mechanics, not many things are known about Artifact. According to one of the developers, the game will heavily focus on the story.
Also, it appears that Artifact will involve building barracks, creeps, and lanes, all of these being part of the Dota 2 game available on the PC. Valve's Artifact will be launched on desktop and mobile (Android and iOS) sometime in 2018, but we hope more information about the card game will be revealed much earlier.
