The killer

The Killer is an unknown masked assailant who has been methodically killing former members of the A.C.E.S. he appears in the first chapter "Wake Up Call" where he is occupying an abandoned building surveying Mike's apartment. He has been watching Mike through binoculars and has set up a camera with a telescopic lens and a make-shift dark room to develop photos he has taken of Mike. There are some notes left behind that keep record of Mike's movements during the day.
He is seen once again on a rooftop overlooking the junkyard in chapter 3 "Shifting Gears" watching through binoculars. He is absent in level 4 but the remnants of his killings are found throughout Waltz's Estate. The killer had entered the home seemingly undetected and killed all of Waltz's armed bodyguards. The bullet holes in the living room suggest there was a firefight between the bodyguards and the killer. At some point during the struggle, the killer ran out of ammunition and killed the wounded bodyguards with his hands. The killer thought ahead and decided to wear gloves during the slayings so it was impossible to get identifying finger prints from the crime scene. 
The killer had also killed Waltz in his bedroom, using a sharp object to skewer Waltz into the wall, killing him instantly. At some point the killer had intentionally placed a torn bit of a comic panel featuring Captain Spade in the kitchen downstairs. The eyes in the drawing were removed and an ace of spades card was taped to the panel, featuring a skull and an inscription reading "See You Soon." possibly left for the police, or Mike. 
It is alluded that the killer has slain other aces as well, as mentioned by Nightwave and Waltz. Waltz mentions in his journal that Billy, John, Alexia and Stephen have all gone missing with being found dead and Mike being able to find Stephen's body in a shark cage at the Mccarthy Waterfront. It is unknown whether the other A.C.E.S. are alive or not. Another body of a man can be found in an apartment building overlooking the Moth and Flame where it appears he was slain with an axe. A note was scrawled on the wall with the victim's blood with the words "Eyes Watching You."
It is currently unclear what the motive is behind the killings.
===Trivia===
* The Killer seems to have an affinity for comic books. There are scattered comics found in the abandoned building he watching Mike from as well as leaving a torn out panel on Waltz's fridge. He is also seen placing an ace of spades card into a comic book with what appears to be images of Mike and Nightwave in the final cutscene. A note can be found in the first chapter that describes someone buying every back issue of old aces comics.
* The Killer wears a metal mask and gloves to hide his identity.
* His physical appearance appears to be a very thin man wearing a long coat with a green scarf and metal mask. Mike describes him as a "tiny fella" by looking at the height of his hand prints and shoe size. Suggesting he is somewhere between 5'8 and 5'11
* Mike suggests that the killer may have a limp either from being wounded in the fight with Waltz's bodyguards or just having one naturally. 
* The Killer seemed to have a personal motive behind each slaying, and leaving behind a signature that may fit the modern description of a serial killer.
