Alissa Vincent
Chief Security Officer of the USG Ishimura
Alissa Vincent was the Chief Security Officer of the USG Ishimura who fought through the outbreak after Marker 3A was brought aboard. She died launching a warning beacon, unaware the Marker had manipulated her into luring more victims to Aegis VII.
Alissa Vincent was the Chief Security Officer and head of P.C.S.I. Security aboard the USG Ishimura. When the ship recovered Marker 3A from Aegis VII and the outbreak began, she led her division against the Necromorphs, saved a number of civilians, and made a final attempt to warn anyone who might follow. She died launching a distress beacon, never knowing her signal would draw still more victims to the ship. (Dead Space: Downfall)
Service aboard the Ishimura#
Little was recorded of Vincent's life before her service as Chief Security Officer aboard the Ishimura. At some point in her career with the Concordance Extraction Corporation she became head of the ship's Security Division, and despite her executive rank she continued to lead a portion of that division as a team leader in the field. (Dead Space: Downfall)
When the Ishimura was dispatched to Aegis VII and brought Marker 3A aboard, Vincent protested, pointing to the violent incidents that seemed to follow the artifact. During the massacre on the colony she demanded that the ship send a squad down to investigate the situation, but she was repeatedly refused by Captain Benjamin Mathius. (Dead Space: Downfall)
The Second Aegis VII Incident#
After a shuttle fleeing the colony crash-landed in the docking bay, Vincent led a squad of officers to investigate the wreckage. They found the shuttle covered in blood and followed a trail of bloody footprints to the Morgue, where the mutated body of a homicidal prisoner named Hans Leggio sprang to life and mortally wounded an officer named Dobbs. Vincent and her team gunned the creature down, but as their teammate Shen moved to help Dobbs, another Slasher, once the nurse assigned to watch the prisoner, came out of the shadows. Her squad was rescued by a devout Unitologist named Samuel Irons, who tore the Necromorphs apart with a Plasma Saw and inspired the others to fight in kind. (Dead Space: Downfall)
Vincent later encountered a group of survivors in an infected zone of the ship. Despite the protests of fellow officer Gabe Weller, her team subdued one of them and placed the rest under arrest, and Vincent contacted Senior Medical Officer Nicole Brennan to have the colonists checked for signs of the spreading infection. Leading her remaining team back toward the Bridge, she lost more of them to the Necromorphs and to the madness the Marker spread: an officer named Hansen went insane and killed Shen, then turned on Vincent, only for Ramirez to kill him. (Dead Space: Extraction; Dead Space: Downfall)
Stopping Kyne#
Reaching the Bridge, Vincent discovered that Dr. Terrence Kyne had overridden the ship's gravitational controls and meant to crash the Ishimura into the planet below. On the way to stop him, she and her remaining people found another group of survivors under attack. Vincent offered to distract the Necromorphs while Irons and Ramirez evacuated the survivors through the vents, but Irons forced her to take his place and drew the creatures off himself, dying as an Infector turned him into a Necromorph. (Dead Space: Downfall)
Vincent and Ramirez reached the door to the gravitational controls only to find it locked. Ramirez overrode the lock, but realizing he too was succumbing to the same madness that had taken Hansen, he sacrificed himself to slow the Necromorphs at the door. Vincent went on alone, confronted Kyne, and subdued him after he insisted the Marker was responsible for everything and must not be returned to Earth. She restarted the engines, but Kyne fled with her weapon before she could enter the codes needed to fully deactivate the drift. (Dead Space: Downfall)
Sacrifice#
Vincent wandered to the docking bay and was cornered by a horde of Necromorphs. She broke for the Marker and discovered that the creatures could not approach it, held back by the dead space surrounding the artifact. She slept in its shelter, and on waking was greeted by an apparition of Ramirez telling her to finish the job and save the ship. Seeing the downed shuttle in the bay, she understood what she had to do. She recorded a video distress call stating her belief that the Marker was responsible for everything, and that both it and the Ishimura had to be destroyed, then activated the venting cycle and ran for the shuttle. (Dead Space: Downfall)
As the bay doors opened, the decompression blew many Necromorphs into the vacuum. Clinging to the shuttle, Vincent managed to activate and launch a distress beacon into space. Despite her efforts to hold on, she was pulled into the vacuum and died shortly afterward, unaware that her beacon would lure more victims to Aegis VII. Her body drifted off into the dark, unnoticed by the USG Kellion as it approached the Ishimura in answer to the very signal she had launched. Her last days aboard the ship are the plot of the animated film Dead Space: Downfall. (Dead Space: Downfall; Dead Space)
Character#
Vincent was headstrong and protective of human life, which often set her against her superiors. During the incident she was responsible for saving a fair number of civilians and for stopping Kyne from scuttling the ship, though the Ishimura would remain in a deteriorating orbit until the arrival of Isaac Clarke. She was slow to show signs of Marker-related illness even as her squadmates were drastically affected, a sign of real mental and emotional fortitude, and she developed hallucinations only at the end, when she was directly beside the Marker.
