From Eurogamer: “Artifact is a mess. 101 players are in game at the time of writing, with the 24 hour peak being only marginally better at 124. Valve hasn’t said anything about the game since 29th March, when the company announced the team will “be heads-down focusing on addressing these larger issues instead of shipping updates”. The most action Artifact has seen on Twitch in recent months was when people decided to stream full length movies and porn in the game’s section. Artifact, at least for now, is a dead game, and arguably Valve’s most spectacular failure to date.”
