Instead of immediately logging your IP and forwarding this information to the FBI, the game posted a message to the victim's wall, stating, "I hope you get killed by a hitman!" followed by a video of Agent 47 blasting their profile pic to kingdom come with a sniper rifle. (Alternatively, if they were one of those people who don't use their own likeness as their avatar, you'd see him shoot a defenseless kitty right in the face.)
If you prove yourself cold and callous enough, you graduate to puppy murder.
After realizing that they just released a tool that handily combined death threats and cyberbullying for the murderous modern asshole on the go, Square Enix pulled the app.
Everyone terminated in the game was also terminated for real, just in case they ever decided to snitch.
