Lapso is a single player first-person exploration game, with particular attention paid to the environmental narrative and sound. It develops through the figure of a scientific illustrator camping near a lake, documenting a special assignment.

Delve into the Rockrose region, backed by mountains and hemmed in by the sea. Before the incident, its trails were travelled by hikers and pilgrims, now it is a place frozen in time, where the animals fled long ago. Put yourself in Ilai's shoes, a scientific illustrator caravan camping on the edge of the lake in the 1970s, undertaking a special assignment. One day, he discovers an unmapped section of forest and everything changes. Explore Rockrose's autumn in search of oddities, visit its abandoned places and discover its secrets.
