A school shooting videogame made by the parents of a victim aims to change minds about gun control: 'This is not a scary game, it's an educational game'
It sound like most didn't read the article.
You aren't playing as the shooter, it is a horror game where you are the victim trying to escape and/or hide from the shooter.
I haven't read the article, probably won't, doesn't really interest me. But I thought the title pretty clearly implies you don't play as the shooter. I'm surprised others didn't interpret the same way.
