The Left Hall returns in Ultimate Custom Night mode, this time serving as a hallway for several of the animatronics to attack from.
The Left Hall appears similar to its first game counterpart, with some few additional decorations to its design. Right there, the Discount Cooling Unit and Sanitation Station from FFPS appears beside the Closet room. Plus, a poster of Twisted Wolf from FNaF: The Twisted Ones makes a cameo alongside a Halloween poster that appeared in William Afton's Alley screen. Overall, this hallway doesn't appear to be changed that much in comparison to other rooms.
