It wasn't the reach that anxious people but it provided a clear example of a video game that almost everyone is calling inappropriate.
Active Shooter was developed by Revived Games and published by the company Acid, which has said it plans to sell the game for $5 to $10.
Valve claims that the game's maker "is a troll, with a history of customer abuse, publishing copyrighted material, and user review manipulation".
Stephanie Robinett, the woman who started the petition, says she is relieved that Valve dropped the game from their platform. "We can't expect those people to be the only ones who stand up against things like this". The simulation racks up points by the number of civilians and police that are shot and killed.
To be clear, Active Shooter was not created by a major developer. Previous links to the game now redirect to Steam's homepage. Groups of users on the site have posted comments celebrating school shooters in the past, according to a March article from Vice publication Motherboard.
A disclaimer by the game developer, Revived Games, said the game "is meant exclusively for entertainment purposes and simulation". Demands from anti-gun charity The Infer Trust have proven fruitful, causing Valve to launch an investigation into the title, alongside developer Revived Games and publisher Acid. Content that is "patently offensive or meant to shock or disgust viewers" and "content that exploits children in any way" are both on the list.
Acid shared a clarification on the Steam Community forum, writing "this game does not promote any sort of violence, especially any soft of a mass shooting", adding, "After receiving such high amount of critics and hate, I will more likely remove the shooter's role in this game by the release, unless if it can be kept as it is right now". Bill Nelson, weighed in on the issue as well, calling the game "inexcusable".
But the school setting of "Active Shooter" hit a nerve with tens of thousands of people as the United States faces a rash of school shootings that have killed dozens of people in 2018 alone.
