P.S.C.I. Badge
"Our job is the safety of the crew. The way I see it, we have two options: Fight or die. We don't have the luxury of running."
—Alissa Vincent[1]

The Planet Cracker Starship Ishimura Security, or P.C.S.I. Security, is the police force on the USG Ishimura.

During the events of Dead Space, the swiftness of the Necromorphs caused an utter break down in command. The security personnel were not able to organize a valid defense. Throughout the incident, one-by-one, each crew member was killed, culminating in the death of their commanding officer, Alissa Vincent.
