The new biome is going to be a Racing Arena! There has been previously one-sheet arena maps and two-sheet arena maps, now it's time for a full 4 sheet arena! The map doubles down a racing track you can use to run around, depending on what you want to do with it! There will be 2 versions of it: the arena during the day and the arena during the night, having different light.
Thanks for a fantastic idea Tristan!
