One Night Ultimate Alien is the next game in the award-winning hidden role blockbuster One Night Ultimate Werewolf series, which includes Daybreak and Vampire. Like its predecessors, every player takes on a different role, with many of those characters having a special action to do secretly, after which the players try to determine who among them are Aliens. The catch is, roles can change and in addition to figuring out who the bad guys are, you need to figure out what role you are as well! One Night Ultimate Alien provides several new roles, most of which have dynamic rule sets, with the app changing things up each game. One Night Ultimate Alien can be played as a stand alone game or combined with the original game, its sequel Daybreak and the Vampire prequel.
