Valve has announced that Artifact, the Dota 2 card game made by Richard Garfield, is due to be released on Steam on 28th November.
The game is also due to be shown publicly at this year's PAX West, so we should hear a little more about it in a month's time.
Valve has kept its cards close to its chest so far, but what we do know is Artifact will mix features from Dota 2 with those of a traditional trading card game. Like in Dota 2, players will be able to control three lanes of action at the same time, and there will be some familiar faces in the form of heroes and creeps. In the latest press release, Valve repeated its claim that Artifact will "give Trading Card Game enthusiasts the deepest gameplay and highest fidelity experience ever in a fantasy card game".
