DOME is based on Shizuko Natsuki's novel of the same name. The original work as well as the game's plot focus on the construction of a nuclear shelter called "The Dome", capable of protecting humans from an impending atomic war. The player takes the role of an employee in an advertisement company, whose job is to raise people's awareness of the shelter's importance, and donate money to the project. Novelware was a concept to oppose tiresome gameplay and at the same time present serious text-intensive stories. Game scenario reached over 700 pages which was unseen before.
