Alright so here’s a guide to Among Us controller, formatting is probably shit because this was copied from Discord and on mobile:
Left Stick – Motion. This part inputs WASD, so if you’re in the middle of a meeting, don’t use these, or else your message won’t quite look right.
Left Stick Press/A-Button for Xbox – This basically functions as the space bar. When walking up to an object, click it and it’ll open it up, just as the space bar would.
Right Stick – This is basically your mouse. Move this around and it’ll control your mouse on the screen. The sensitivity is a bit messed up, but you’ll get used to it.
Right Trigger – This functions as a click and/or a hold on the mouse. Use this along with your right stick to do tasks.
FOR IMPOSTORS:
Left Stick Press/A-Button on Xbox – This opens up your sabotage menu.
X-Button for Xbox – Use this one to kill people. Simple as that.
And that’s about all you really need to know. There are also extra button inputs depending on what buttons you’re pressing, but in terms of functionality, these ones’ll be the best you have.
