In Robotics;Notes, there is some sort of robot outbreak in the city. They all go out of control and attack what seemed like the city hall.
When Frau tries to hack into the servers to stop the outbreak, she is redirected to the Kill-Ballad game. When Kai beats the enemy, access is given and they manage to stop the outbreak.
What was the point of using Kill-Ballad to block the access to the servers? Couldn't the enemy just say "nah, you don't have access, go away" rather than giving a chance to actually stop the outbreak?
