A new Limited Time Mode has been found by @TwoEpicBuddies in the Playlists section of the game files. The ‘Impact!’ mode will only be available for Solo play and likely has something to do with the comet seen in the sky:

While none of this is official or confirmed, the majority of modes found in this section have been released into the game at some point. We’ll update this post with any additional information.
