Twisted Metal: Black was to have a sequel titled Twisted Metal: Black - Harbor City, though it was never officially announced and the project was later scrapped. Details on the game were revealed in the PlayStation 2 port of Twisted Metal: Head-On, Twisted Metal Head-On: Extra Twisted Edition. It was originally planned the levels of Harbor City to be greatly expanded and inter-connected with one another, giving a greater feeling of a single, complete world rather than stand-alone levels. The four completed levels were included in the game as a bonus feature entitled Twisted Metal: Lost.
