It’s been a while since Valve announced a new game, but that all changed minutes ago with them announcing a brand new game. You may have already guessed it, but it’s another card game.
It’s called Artifact and it’s a DOTA 2 based online card game. It’s based on three-lane gameplay which separates it from standard card games. It’s clear that this is an announcement based on Blizzard’s success of Hearthstone and Bethesda’s success of The Elder Scrolls: Legends.
