We're releasing several terrain maps freely available at the Unity Asset Store a little later today. Few of them we created to use in our game demos. They'll be untextured and without additional props but free for any use, even commercial (just as long as you don't reproduce exactly our landscapes from the game!). We can spare to freely share a few maps, since there'll be over 100 more in the game!
PolyKhrome will periodically release free assets from our game Cyka available at the Unity Asset Store and TurboSquid, and BlendSwap. We like to share some of our work with others, and encourage people to use them in whatever creative ways they can imagine. You can expect more releases periodically in the future. And hey, we'd love to hear from you about how you used them! Post them on our Facebook page! Enjoy!

[5/25/2012] Update: Bare with us, folks--we've decided to provide some detail assets to the free untextured terrain maps, such as rocks and trees. We're also uploading a package of 3 large maps for purchase at $10 that are fully-textured, loaded with animated and static props assets, low-poly and ready for any game production. We'll post them up on the Unity Asset Store at the same time and post up a link to them both when we're done.
