We are in 50 B.C. where Gaul is entirely occupied by the Romans. Well, not entirely... One small village of indomitable Gauls still holds out against the invaders. Life is tough for the Roman legionaries guarding the fortified camps of Totorum, Aquarium, Laudanum, and Compendium.

One day, Panoramix receives a strange letter. It is from Avina Gandir, the priestess of Thule, who warns the druid of a serious threat to his people and asks him to retrieve a mysterious Menhir from its hiding place.

Embark on an exciting adventure and immerse yourself in the world of Asterix! Alone or in co-op with your friends, explore the lands of the Roman Empire and uncover the mystery of the Crystal Menhir and its incredible powers!
