Not Alone is set in the 25th century. You are part of an intergalactic expedition that has crashed on the mysterious planet Artemia. While you wait for the rescue team, you decide to investigate the planet. But an alien is hot on your heels and on the hunt... You are clearly not alone! Will you manage to brave the dangers of Artemia?

Not Alone is an asymmetrical card game in which one player (the Creature) competes against all other players (the Prey). If you are part of the Prey, you research Artemia using Location Cards. By playing these cards together with Survival cards, you try to avoid, confuse, or distract the Creature until reinforcements arrive. If you play as the Creature, you hunt the castaways. By playing your Hunting Cards and harnessing the mysterious powers of Artemia, you try to undermine the Morale of the Prey and allow them to be absorbed by the planet.
