Herro. :3 I'm assuming you're new here? Welcome!
Maps included with FH are Lonely Cave, Ascension Island, Sky's Rim, South Pole, Atlantis, Ficho, Temple of Dreams, and Cape of Distant Worlds.
And there's plenty of stuff to do. You can fly around, explore, make friends, create new characters and presets, and even make your own maps and meshes. Have fun and enjoy the game :3 If you need any more help, feel free to ask!
