The freeplay map is randomized to some extent, there are some loctions that state the same. Like toxic bunker and radio tower are always in forest. But the tip i can give you is always go in one direction.

There are 2 ways you can get in and out of the forest.
-The first one in an underground passage:
-The second one is a big gate way:

No, the freeplay map is not randomized, there is just some locations that look the same.

The normal part contains:
-Bunker
-Garage
-Apartment

The forest part contains:
-Toxic tunnel
-Radar tower

I weren't able to photoshop all the images and put it in because Steam has a limit on posting images. So i have to put each image idividually. The process of making this was painful, taking screenshots everywhere. I wish i could have just put all the images together.
Sorry for the very bad image quality, My computer couldn't handle so many screenshots in the disc space without lagging so my PC compressed the images and made the quality low.
