But what Shadow did not expect is that he was infected with a substance that drove him crazy to such a point that Shadow became a superior crazy being without control. You were a police officer from the "G" foundation, the largest elite in Vanilla City.They never call you because if they talk to you it is a very serious case. So that the city recovered from the pandemic, no one went out since they did not want to get in Shadow's way while pink smoke spread through the city like fog that was difficult to see.
