Among Us: Hide and Seek is a demo version that was developed by Innersloth studio. This part is different from the original, but it contains elements from the second part. Of course, it requires 10 people. To play, you just need to download the app. You must have an account on Discord server. The plot is very simple: on a huge map, you need to find a place to hide and try not to become discovered.
However, that is how it used to be.
At the moment, this channel is no longer working. Perhaps the developers are working on interesting updates, and maybe this story will no longer be in the series.
