Dust Hill was pretty similar to the lone screenshot of it, a standard desert themed level. After completing Emerald Hill and Chemical Plant Zone, however, I ended up in Dust Hill. I started playing the beta, aside from Tails not being present in gameplay, the game initially seemed identical to the final version. I was skeptical that such a thing would exist, since most deleted levels are cut because they were never finished, but the download description claimed every zone had been completed, and removed for an unexplained reason. Recently, I came across what was claimed to be a more complete beta of Sonic 2, which had all the missing zones intact and fully playable. The lack of information and excessively threatening name have made this zone one of the biggest mysteries in gaming. Selecting it in the beta will simply load a blank screen where Sonic will instantly fall to his death.

Hidden Palace and Wood Zone can be partially played, and there is an old preview picture of what is believed to be Dust Hill. Hidden Palace, Wood, Dust Hill, and Genocide City/Cyber City are all listed on the level select screen of a publicly available Sonic 2 beta. Deleted levels in video games have always been a source of fascination for gamers, and one of the best known examples of them is the four deleted zones in Sonic 2.
