I imagine the game will be free to play with packs you can open and a ton of loot chests with cosmetic card backs and more. I am curious if there will be some shared loot with Dota 2 though? Also wondering how different Artifact will be from other existing digital card games on the market or if Valve will do something different? Will there be a VR component to Artifact? Are you interested in Dota digital card game from Valve?
So many questions that will be answered as time marches closer to the 2018 release date.
A few websites are noting a few details about the game, i've clipped the important bits below:
"The digital card game will be out in 2018. It’ll feature lanes, use characters like Bounty Hunter, and have cards like barracks that will push waves of minions down each player’s avenue of attack. It’ll be a card game version of Dota 2, essentially."
