Miles Upshur is an investigative reporter and the unseen protagonist of Outlast and a secondary character in Outlast: Whistleblower. He arrives to investigate Mount Massive Asylum based on a lead he received from an anonymous source.

According to the beta version of the Whistleblower document, Miles originally worked as a regular journalist for an unknown company before being fired, as a result of posting unacceptable material regarding the situation in Afghanistan. Since then, Miles has been self-employed as an investigative journalist.[2]

Prior to departing to investigate Mount Massive Asylum, Upshur lived in an apartment in Washington, D.C.

Miles is capable of surprising athletic feats, from climbing to leaping across ledges, and is able to escape even the fastest enemies. While not physically weak, he is no match against the psychotic prisoners known as the Variants. Instead of fighting them head on, he chooses not to engage them directly and relies on his speed and agility to escape harm and hide from them. The only exception to this is certain scripted events, like when he fights off patients or Variants who attempt to strangle him, or when Richard Trager pursues him into the elevator. He will often hide in lockers, under beds or simply blend in with the darkness to avoid pursuing Variants. He brings along with him a notepad to write down his thoughts and a handheld camcorder to record the happenings in the asylum. Its night vision feature allows him to navigate through the darkness.

Miles heads out to Mount Massive Asylum after receiving an email from an anonymous source about the suspicious activity that is going on at the asylum. After finding a way in, he is greeted with a grim discovery: the dead bodies of staff, security guards and tactical operators—one of who warns him about the imminent dangers that lurk in the asylum before dying.

Miles observes some patients moving around the asylum before he is grabbed by Chris Walker. Chris exclaims, "Little pig..." and throws him a floor down through a window. Upon regaining consciousness, Father Martin finds him and, after seeing his video camera, calls him an "apostle" to the deeds being done at Mount Massive Asylum. Miles attempts to unlock the main doors using the Security Controls but is thwarted by Father Martin after turning off the power, with Walker tracking him down in the security room.

After Miles restarts the generator in the basement of the Administration Block and returns to the Security Control room to open the main doors, Father Martin overwhelms him and injects him with a sedative. He says that he cannot allow Miles to leave just yet. He shows Miles security footage of soldiers being slaughtered by an entity called The Walrider, and that he has to accept the gospel so all doors before him will open. Miles then blacks out and is transported by Father Martin to the holding cells in the Prison Block.

Miles wakes up in Father Martin's cell, with the phrase "Rest in Peace" written in blood on the wall. As Miles leaves the cell, he encounters The Twins. They discuss killing Miles and taking his tongue and liver, but eventually decide not to do so yet, as it would be impolite towards Father Martin, who told them not to touch Miles. After traversing the Prison Block, Miles enters the Sewer through a hole in the shower room where he has to drain the water in order to continue.

After going through the Sewer to reach the Male Ward, Miles is chased by a few patients. During the chase, Miles escapes in a dumbwaiter and meets Doctor Trager, who ambushes him and takes him captive. Trager then tortures him by cutting off two of his fingers with a pair of large bone scissors, but Miles manages to escape when Trager leaves the room. Miles eventually finds the key to the elevator. Trager opens the gate when the elevator passes him, but Miles is able to hold him back. Trager is crushed by the elevator, killing him.

Miles then meets up with Father Martin, who tells him to meet him outside. Miles encounters The Walrider from here onward as he progresses through the Courtyard. Father Martin is next seen inside the Female Ward, where he shouts down at Miles from the upper floors, telling him how to reach him. Miles has to open the laundry chute by collecting three fuses from the nearby rooms to get the key which unlocks the stairwell to the upper floors. During a jump, Miles loses his camcorder as it falls down through a gap, and he is forced to descend into the darkness without his night vision to get it back.

Although Miles doesn’t speak during the events of the game, his personality shows in the game’s introduction text and the notes he writes as he continues to try and escape the Mount Massive Asylum. As stated in the intro, Miles is a highly ambitious reporter who is willing to do almost anything to get the story even if it means putting himself in danger. When he is tipped off by Waylon Park about Murkoff’s involvement at Mount Massive, Miles sets out immediately to the asylum and decides to illegally break in despite the danger.

Miles is a cynical man; he can be seen using extreme profanity and also uses rough insults towards his enemies in writing, which is a large contrast to Waylon's gentle and reserved personality. He cracks dark jokes towards certain situations, such as calling Trager a "white collar business school douchebag", and tells another joke after killing Trager; he is very vengeful after Richard sliced off his fingers, demanding reprisal. Despite his sharp nature, Upshur's ethics are that of a selfless, albeit stubborn individual who's willing to risk his life to stop the Walrider and expose Murkoff for their violation of basic human rights.

Furthermore, due to the intensive injuries he can endure and his sheer determination, Miles is likely a strongly willful man. Throughout the game, Miles slowly loses his sanity due to his witnessing of the horrors in the asylum and being exposed to the Morphogenic Engine, though his implied sanity decay does not show too much in his notes, only subtly subconsciously hinting towards it (such as when he begins to randomly spout random sentences at the end of notes, such as "The buzzing won't stop." And "It's like an itch"). An interesting note is that he is very sympathetic to Walker's death, who has ironically caused him the most trauma throughout the chaos.

Miles, like most characters, appears as a well-built adult man with fair skin. His face is never seen, but his shadow reveals he has short, dark brown hair. His attire includes a brown work jacket unzipped to reveal a white dress shirt tucked into his blue jeans and a black belt. He also wears brown work boots. His left ring finger and right index finger are cut off after his run-in with Trager, splattering his hands and sleeves in blood.
