This Among Us Itch.io Version is Updateing? Or Dead and Only Steam? And its Have a Cross-Play?
As far as I know, itch.io version is up to date at present, most recently updated about 3 months ago. Steam has a beta branch which isn't available on itch.io and I don't know how active that version is in terms of updates or if there's any special requirement for accessing it, but the base game is cross-compatible on both platforms as well as mobile. And the game is on Epic now as well.
