Among Us has hidden features in the game. One of those is a flipped version of Skeld. To simply get it, change the date of your device to April 1st, 2020. Then host a game, and you should have a flipped Skeld. This only works for Skeld.
There are also Halloween-styled maps. By changing your date to October 31st of 2020, you will play on a Halloween-styled map. Not only that, you will get all Halloween hats.
You can also get Christmas hats by switching your date to the 25th.
