The International One Night app is designed to be used in countries where English is not the primary language (and who have devices that use a language other than English) with One Night Ultimate Werewolf, One Night Ultimate Werewolf Daybreak, One Night Ultimate Vampire, and One Night Ultimate Alien party games published by Bezier Games. You will need at least one of these games in order to take advantage of this app. This app automates the night time narration based on the roles in your game, and provides a timer that can be used for the day phase of the game. This is not a localized version of the app; it contains text and narration in English only.
