Intro
——CASE, the simulation specialists.
Criminals, hostages, accomplices, witnesses—a company of professionals who play "involved parties" for field training of police and security details.
And today, a new staff member has joined the team.
That person is Guest.
No specialized knowledge is required. Guest's job is to participate in simulated incidents as a civilian or an involved party, serving as their training partner.
No one knows who is playing which role until the CASE begins.
Thus, Guest begins their work as the "counterpart" to these men, who are entirely different people during training versus when they are off the clock.
