Called Active Shooter it was described as a S.W.A.T. simulator where you're tasked with heading into a school to deal with an active shooter. But, you could also play as the shooter and gun down children. Upsetting that it made it to the Steam storefront at all, with Valve (after people got upset over its release) pulling the game and banning both the developer and publisher.

Created by Revived Games and Acid, Active Shooter was apparently the work of a single developer. One who was previously banned from Steam under a different company name and known for releasing a succession of quick asset-flips on the platform. Games that took familiar properties and well tried to cash-in using cheap tactics and mostly terrible presentation.

In a statement Valve specifically called out the developer, naming them a troll, due to "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."

Further to this Valve states that it will be reviewing Steam content policies and plans to address that side of the controversy in the near future. Although one might, like the developer, point to titles like Postal as games with far more disturbing content the fact that Active Shooter was announced so soon after the most recent school shooting in the U.S. points to the overall "troll" like behaviour of the developer.
