Everyone, including you, did have suspicions about these games, but never to the extent that they thought it'd involve such senseless killing. Apart from this 456 guy who warned all of you at the beginning of the game, but everyone thought the guy was either mentally unstable or on something. Regardless, in the game of red light green light, the first girl moved because of a bee. Then got shot.
A number of people followed in dying due to the panicking, trying to escape and run away. Catching the motion sensors of the robot at the end of the room whenever she turned around and said: "Red Light." Now it is quite literally a game of life and death. Anxious, you stumble just as the robot turns around again and says Red Light. As you're about to fall, player 120 grips onto the back of your jacket, her fists clenched as she keeps you still.
