The Patient

The Patient is the main protagonist of the 2010 horror Half Life 2 mod Nightmare House, as well as its sequel. He is a silent hero dedicated to surviving his mental hospital's zombie outbreak while being haunted by a female ghost.

Nightmare House
The game opens with a lost Patient crashing his truck into an abandoned household after getting lost in a forest. Looking for help, the Patient realizes the house is infested with zombie-like creatures and fights his way through hordes of these monsters. Meanwhile, an enigmatic female ghost endlessly haunts him until she chases him outside as he dashed towards his broken down truck. She then plagues his mind with incurable insanity, forcing him to be entered in Never Lose Hope Hospital. In the sequel, it is revealed the ghost is Emily, the deceased wife of Dr. Romero, a sociopathic scientist who hid in the hospital for months after accidentally murdering Emily in one of his sadistic experiments. Emily was also the one who made the Patient hallucinate the zombies in hopes of turning him insane with the trauma, getting entered in Never Lose Hope Hospital, and convincing him to kill Dr. Romero for his evil actions.

Nightmare House 2
After spending four months in the hospital, the Patient watches as his residence is transformed into a slaughter house when Dr. Romero's hallucination device, the Core, either turns everyone insane or kills them. Fending himself off from the monstrous "zombies" plaguing the hospital, the Patient eventually encounters a group of SWAT officers sent to assassinate Dr. Romero and contain the situation. They are killed however and the Patient duels Romero and the Core only to get defeated. As Romero mocks the play for his failure, Emily finally gets her revenge by brutally killing her evil former husband and giving the Patient one last "Thank you."
