Valve’s upcoming Artifact Preview Tournament will show off the Dota card game’s built-in tournament system.

This weekend’s event will see 128 players compete over a slice of the $10,000 prize pool. It will also show off Artifact’s tournament system, which is built straight into the game’s client and allegedly free for all players.

"Hosted by Beyond The Summit and broadcast on SteamTV, the all-draft event will feature a 7-round Swiss bracket on Saturday," said Valve, courtesy of PC Gamer. "A top 8 single-elimination bracket will decide the winner on Sunday. Both days begin at 9 AM PST."

The Dota card game is set for release on November 28th, with the game’s beta test period starting nine days earlier. Despite the natural comparisons, however, Valve doesn’t see Artifact as a direct competitor to Hearthstone.

But the wait for launch hasn’t kept Artifact clear of controversy - back in October, Valve was forced to change some particularly tone-deaf wording on an example card.

Artifact represents a return to game development for Valve after the company started to focus more of its attention on hardware, namely VR. As an indication of its commitment to making software, the firm purchased Firewatch maker Campo Santo to bring that development talent into the company.
