First reported by Insider Gaming, users on 4chan have shared assets purportedly originating from the 2021 CD Projekt hack that show a lunar surface area either cut from Cyberpunk 2077 or intended for a canceled DLC.
The initial post characterizes these images as coming from a canceled DLC that would have taken place during a new "corporate war," and compares its scope to the Witcher 3's Blood and Wine expansion. That interpretation, as well as the images' provenance, should be taken with a grain of salt, but the extent of what's on display, including an out-of-bounds view of one area that includes Cyberpunk's HUD, leads me to believe they are legitimate.
