An Australian software developer created the game where players can shoot their mothers and go on a shooting rampage in a school.

The Sydney gaming geek, believed to be called Ryan Jake Lambourn, has reportedly caused “deep anger and fury” among families of the victims and survivors of the horrific massacre.

His simulation — “The Slaying of Sandy Hook Elementary School” — sees players re-enacting the fateful day of Dec. 14, 2012.

…Lambourn…has defended his game as being key to restarting the gun-control debate in America.

Refusing to back down, he tweeted: “The liberals don’t like me because I’ve disrespected the dead. The conservatives don’t like me because of the gun-control message. The conspiracy theorists don’t like me because it risks informing people of what happened. And the trolls don’t like me because it wasn’t edgy enough.”
