Players once again take control over the detectives Neo McDonald or Geo Kentucky, who must explore the city and interrogate people. The sequel adds games, automobiles, politics, adult titles, and trivia to the list of questions the players must answer to. Much like the first game there are two scenarios to explore, though this time the game gives players the scenario option at the start. The Sugoroku Mode from the first game is absent, making this game a strictly single player experience.

- In the first story scenario "Love Over Time" (時を越えた愛), Neo & Geo travel to 1942
- In the second story scenario "Client from Space" (宇宙からの依頼人), Neo & Geo work to solve an alien conspiracy taking place on Earth.
