The game system consists of “Investigation” and “Somnium.” The “Investigation” part takes place in the real world. Here players will examine crime scenes and listen to testimonies. In the “Somnium” part, players enter the dream worlds of suspects and key witnesses.

During a Somnium, players have a limited amount of time to search for the truth deep in the subject’s memories. Aiba and Tama appear in human form and assist their agents by exploring the dream world and uncovering new clues.

—At ABIS headquarters an Agent or “Psyncer” uses the Psync machine to enter a witness’s dream world. The device can only be used by Agents with the ability to adapt to the dream world.

A Somnium is uniquely based on the memories of the Psync subject, so each dream landscape is completely different. The sequel introduces new underwater and aerial Somnia, allowing players to experience more varied worlds. Somnia are comprised of multiple levels, and “mental locks” that must be unlocked in order to advance to the next level. Depending on the Somnium, there are multiple ways to remove mental locks, so the story may diverge depending on what method was used.

To remove a mental lock, players must examine and act on various objects, but every action consumes its own set amount of time. With only six minutes to complete a Somnium, players must take into account the remaining time and choose each action carefully. While taking action time flows at a normal speed. Remaining stationary causes time to pass more slowly.

■ Somnium “Keys” and “Conscious Antibodies”

Keys

In a Somnium, common sense and laws of the real world do not apply, but there are “Keys,” or rules based on the Psync subject’s consciousness and memories. Once Keys are revealed, it becomes easier to narrow down the actions and choices to be taken in that Somnium. Initially, most of the Keys are hidden, but as you explore and begin to understand the Somnium, Keys will be revealed.

Conscious Antibodies

A Conscious Antibody is the alertness of the Psync subject embodied in the Somnium. Conscious Antibodies block access to important information and, when touched, greatly reduce the amount of time one can safely remain in a Somnium.

—If a Conscious Antibody is blocking the way, find a way to eliminate it and move on.
