Danny inside the sewer system
The Sewer System appeared only in the level Most Wanted in Manhunt 2. Daniel Lamb had to escape through the system from The Bloodhounds to the Train Yard, but he ends up in a garden. There's a gate in the system, that Danny must lower down, a locker room in one of the walls and also a wrecked car. This sewer system is alike the sewer system in Los Santos.
