The Helios Sewers connect Helios City to the Black Market. They can be reached through the basement of the Helios Department Store. The area is very dark and may require the player to pick up the Flashlight while navigating the maze. There is also a puzzle somewhere in the sewers.
If the player is having trouble seeing where to go in the sewers, there is a Flashlight located in the room straight up, right, down and then left from the Helios Department Store Sewer entrance.
Navigate through the sewers and enter the Black Market. The quickest way to do this is, starting from the Department Store, go up, left, up, right, up, right, up until the player stands next to a pool of liquid, left, and then up until the player is standing next to the fan which serves as the entrance into the Black Market.
