When controlling the playable character, the player is limited to moving on rails. Placebo confines all interactive segments to within its protagonist's room or car, but has the addition of an interactive e-mail reading interface on said protagonist's computer. Contact Points represent any interactive element in the game field, such as characters to talk to, implements to pick up, or numeric puzzles to solve. When the player is given control, they rely on a menu to toggle movement, review their items (known as "implements"), interact with "Contact Points" or save their progress.

The game is divided into two parallel storylines: "Transmitter", where the chapters are called "cases", and "Placebo", where the chapters are called "reports". While most of the game's story is conveyed through this visual novel style of presentation, there are also instances where the player is given control of the playable character and are able to move freely, albeit on something of a grid, across three-dimensional venues.Īfter being attacked on the drive home, Tetsugoro Kusabi has the Republic task force dispatched to investigate the Cauliflower building, where the shooter may be hiding.Īs Shirubā Jiken is primarily text-based, players spend a great deal of time reading and observing art panels to learn how the story develops, although three-dimensional cinematics, live-action video clips and two-dimensional anime clips are occasionally used to add depth to the plot. Dialogue is told through traditional text boxes, and as there is often more than one character's image displayed onscreen, a luminous grid traces the speaker's portrait in particular.

These panels are used to illustrate elements such as which characters are present and how the story develops. The plot of Shirubā Jiken is driven mainly by a collage of art panels.
