Sonic 2 seems to have the majority of lost levels. It seems the creators made the game too large so they removed some levels. Also, soon I will be adding pictures of Wood Zone and Genocide City from my friend's foreign copy of Sonic 2. This will mean that my page will be the first to show them. If you have anything to add then Email Me! I now have two pages!!!

I've played Hidden Palace Zone (though Act Two doesn't work) at my friend's house so I know these pictures are genuine. I have more pictures of this zone on the other Sonic 2 pages ahead.

The version of Dust Hill that I've played is exactly like Mystic Cave Zone except that the music has changed and the level layout. More pictures in the pages ahead.

Another picture of Hidden Palace, though this one looks more like the one I played especially the waterfalls in the background and the bridge.

As you can see from the screenshots, the colours are not the same as the final Casino Night Zone. The version my friend has (I just love his Sonic 2 cart!) starts off with a collection of ramps separated by pits making it very hard to get through. His version is almost identical to these screenshots.

If you have a copy of Sonic 2 that only has four zones (starting with Neo Green Hill Zone), then try the Sonic 1 level select (On the title screen, press up, down, left, right, then A and Start simultaneously). My friend tried it on his foreign Sonic 2 and it gave him access to many secret zones including Hidden Palace, Dust Hill, Wood Zone and Genocide City! Genocide City is a load of old cobblers. You just fall and fall until you reach the bottom and die! Wood Zone on the other hand actually works! It has great graphics, no enemies and but only one act works. The problem is that you get stuffed by a large pit preventing any further progression. A shame, really! I have pics of these zones on my site!!!!!!!
