Things have not gone well for Valve's much-publicized CCG Artifact since its November 2018 release. The player count began tumbling almost immediately, from a peak of more than 60,000 players to a concurrent count, according to Steam Charts, of just over 200. It's a remarkable decline, particularly for Valve, which had positioned Artifact as the vanguard of its return to game development. 

Today it acknowledged that things have gone very, very wrong, and said that it's effectively putting the game on hold while it figures out where to go from here.
