Active Shooter, the school shooting FPS that caused an uproar when it appeared on Steam last week, has been removed from the platform, and both the developer and publisher—Revived Games and Acid, respectively—responsible for the game have been banned from the platform. 

"This developer and publisher is, in fact, a person calling himself Ata Berdiyev, who had previously been removed last fall when he was operating as '[bc]Interactive' and 'Elusive Team'," a Valve rep explained.
