The case is subject to SOMBRA off all lights on the planet and can not see anything, so Carmen and the player must use a flashlight all the time, crime scenes and the funds are in the dark, as the case progresses, we'll be meeting with fugitives murderers of SOMBRA but will not be suspicious, and the world will be in danger because there is chaos everywhere and the exploited SOMBRA to "divide and conquer".
