Valve working on a new game, and it's not Half-Life 3

The card-collecting genre is currently in a golden era.

As it turns out, the Half-Life 3 memes will live on after Valve's latest announcement. The developer is currently working on a card game based on DOTA, conveniently titled Artifact - The Dota Card Game.

Not much is known about the game at this moment. It's supposed to be released sometime next year, and the popular opinion is that it's Valve's response to the global success of Blizzard's Hearthstone.

For now, all you can do is check out this teaser that will tell you literally nothing about the game itself. Cool cool.
