The twins

Characteristics: The Twins both exhibit remarkable composure and intelligence compared to other inmates within the asylum, retaining a semblance of humanity despite their insanity. Surprisingly rational and thoughtful, they demonstrate a capacity for strategic behaviour uncommon among psychopaths. An example of this is their ability to open and close doors rather than resorting to mindlessly bashing them open like their fellow Variants. Neither of them wears any clothing. They prefer ambushing targets in long corridors, utilizing their numbers to corner Miles if they had the chance. Operating as silent killers, they do not run or speak during a pursuit, instead maintaining a calm pace and opting for silent kills. Their weapon of choice appears to be iron machete-like blades. Unlike other Variants in the asylum, approaching either of them too closely results in instant death rather than mere injury, as they swiftly stab Miles in the back before decapitating him with their machetes. Furthermore, their lack of noisy accessories and appendages due to their nudity makes pinpointing their exact location challenging, necessitating heightened vigilance and attentiveness from the player. They're also seen together and never encountered individually.

Miles' first encounter with them is at the beginning of the Prison Block, where they discuss killing Miles and taking his tongue and liver, but decide not to do so yet, for it would be impolite towards Father Martin, who told them not to touch Miles. They become hostile later on when they've decided they had enough patience with Miles, despite Father Martin's wishes. They are encountered once more near the prison showers, where they manage to trap Miles in a narrow corridor and he is forced to use the smashed window to evade them. Further encounters include the Female Ward where they lie in wait behind a large door near two hallways and when Miles returns to the Administration Block in the theatre room. They cease being hostile once Miles reaches the Chapel during Father Martin's crucifixion. The Twins make a brief cameo in the Recreation Area. They are seen walking to either side of Waylon at one point, mentioning that he looks nervous and they would like to kill him. Once Waylon loops around to the basketball court, they cease hostility and wait in front of the designated door. They will not attack unless Waylon gets too close. They return to antagonizing Waylon as he hurries to escape the basketball court. After he climbs up the ladder, they are not seen again.

Personalities: The Twins speak in incredibly calm tones, never raising their voices, and speak casually about everything. However, they are murderous cannibals, as they usually talk about indulging their desire to murder Miles and eating parts of his body, such as his liver and tongue. They have what is almost a hive mind, sharing the same thoughts and the same psychopathic personalities. They speak in choppy sentences and occasionally finish each other's statements. They are devoted to Father Martin, making it likely that their insanity bleeds into believing the Walrider religion, and simply walk when chasing Miles instead of running. This, combined with their lack of clothing and never speaking while chasing Miles, makes them almost completely undetectable and silent. They are also cynical, as evidenced by their deadpan use of sarcasm, stating "My god, he vanished" and "Vanished without a trace" when they see Miles climb out of a window to escape them, indicating their awareness and disdain for his assumption of their incompetence. Fortunately, they opt to move on and allow Miles to proceed, possibly following Father Martin's instructions.

Physical descriptions: The Twins, when compared to most of the other Variants, are rather average looking men, showing no obvious signs of scarring or deformity. One is nearly bald and the other has some hair in the middle of his head. Their skin appears to be quite dirty & they are slightly bloodstained. Unlike most other patients, they do not have any severe deformities or scarring caused by the Morphogenic Engine, in fact they have none at all. However, they do share some different then usual physical features, implying that they could have been products of inbreeding. Their most notable trait however, is their complete nudity, having shed absolutely all clothing.

They are usually seen carrying a large machete each, the bald brother, however, is at one point seen wielding a meat cleaver instead. They are also both seen unarmed when standing at the chapel doors during Father Martin's ceremony.
