For those wondering how to update, what I do is I download the game again. You don't have to pay to redownload since you already bought it.
But how do u update it...
You don't need to update it if you redownload he game.Its the same thing: You're deleting the old version of the game and downloading the new version. EASY
Sometimes I don't even delete the old version and it still works.
but among us isn't free in pc lol
