A video game that simulates a school shooting incident has been labelled "disgusting" and "despicable" by parents of children who died during the mass shooting at a school in Parkland, Florida, in February. Billed by its Russian publisher, Acid, as a swat team simulator, Active Shooter invites players to take on the role of an armed officer responding to a school shooting. However, the game also allows users to play as the shooter or as a civilian attempting to escape the scene. Using a first-person perspective, similar to shooters such as Call of Duty, Doom and Counter-Strike, the game looks to be entirely set within a school. Screenshots released by the developer and seemingly taken from the perspective of the shooter show swat team officers and students being gunned down in various locations including a gymnasium, corridors and canteen.
