A recent leak that surfaced on social media hints at the possibility Cyberpunk 2077 could have had an expansion that was set on the Moon, complete with an off-map experience around the size of Night City (excluding the Badlands) itself.
The leak that surfaced on June 15 shows us a scrapped expansion set on the Moon. The leaks consist of images of a lunar base along with maps and file data for what would have been an off-map expansion. The Moon, according to lore from the Cyberpunk 2077 wiki, is heavily colonized and dotted with corpo-run cities that mine resources with a population of around 58,000 people, which would have presented a unique location that is vastly different from the bustling Night City on Earth.
