Valve is about to launch a new game, though it isn't Half-Life 3 or even Left 4 Dead 3. It's Artifact, the trading card game (TCG) announced last year.

　　The game is now set to launch on November 28th, as you can see on the official Steam page, and will be available for Windows, Mac and Linux for a price of $19.99. Artifact is also due to hit Android and iOS devices in 2019 and will be showcased to the public for the first time during PAX West 2018 (Seattle, August 31 - September 3) where players will participate in a 'single-elimination' tournament and have the chance to earn free merchandise and two keys for the full game.

　　Artifact is a digital card game coming from the makers of Dota 2 and Steam. A collaboration of legendary card game designer Richard Garfield and computer game and technology maker Valve (Dota 2, Steam), Artifact is designed to give Trading Card Game (TCG) enthusiasts the deepest gameplay and highest fidelity experience ever in a fantasy card game. It features more than 280 cards in the shipping set, including 44 heroes. Targeted for release on Steam in late 2018, players will be able to buy and sell cards on the Steam Community Marketplace. Artifact will also be supported as a service through expansions, competitive events, and new features.
