The first new level is a sewer. You can check it out at bloodfreeminded.
The second new level is actually a replacement level. It replaces the level "Where Am I?". Instead of a very small cavern, it is set in a forest.
The third new level is in another forest, but with a few swamps, and the textures used for the branches and leaves are a different color, as if the trees are already dead.

Oh I almost forgot, the third new level also has a small shrine in it with a hall that leads to a small courtyard where the gates to a cathedral are accessed.
