Help is a UX element in Among Us, found in the top-right corner within the menus for both local and online games.
Overview
When the help button is clicked, a tab with information about local games will appear if the player is in the menu for local games, and the same goes for online games.
Local
Help for local games includes tips about what to do if there are any issues connecting to a local server as well as a link to Innersloth's Discord server.
Online
The information given for online games includes instructions for sharing game codes with friends, making servers public and private, and kicking or banning players whenever chat is available. There is once again a link to Innersloth's Discord server for those still having problems.
