UPDATE 30/5/18: Valve has removed controversial school-shooting FPS Active Shooter from Steam, and its developer and publisher – Revived Games and Acid respectively – have been banned from the platform.
In a statement addressing the matter, Valve explained that Revived Games and Acid are, in fact, one person – Ata Berdyev. Berdyev was previously been removed from Steam last autumn, according to Valve, when he operated under the names [bc]Interactive and Elusive Team.
“Ata is a troll,” read the statement, “with a history of customer abuse, publishing copyrighted material, and user review manipulation. His subsequent return under new business names was a fact that came to light as we investigated the controversy around his upcoming title. We are not going to do business with people who act like this towards our customers or Valve.”
