PLZZZ MAKE IT FREE ON ANY TYPE OF ELECTRONIC PLZZZ BC MY MOM WONT LET ME BUY STUFF LIKE THIS!!!!
Try getting an Android emulator (like Nox or MEMU, maybe not Bluestacks because I've heard that app is unsafe) and installing the mobile APK there. It will have ads and the controls may not be perfect but it's a legal way to functionally play Among Us on your PC.
I apologize if you meant Among Us 2 when it comes out, hopefully your request will be fulfilled if they un-cancel it.
