About the Game

ExMORTALIS is a chilling First-Person Immersive Sim set in 1893 Argentina, where you awaken as a patient in El Dedo del Diablo—a 12-story Gothic laboratory tower operated by the Necrotechs, a collective of engineers, doctors, and scientists pursuing the ultimate human specimen through horrifying biological experimentation.

EXPLORE & SCAVENGE

  • Navigate the labyrinthine tower overrun by experiments gone awry, your arm tethered to the Necrobiotic Serum

  • Uncover your past and the ExMortalis project through scattered notes, discovering the chaos unleashed upon the Victorian town

  • Experience interconnected tower floors that reward exploration and environmental storytelling

  • Master multiple solutions to every obstacle through stealth, combat, environmental manipulation, or mutation abilities

EVOLVE OR PERISH

  • Voluntary mutation chambers offer powerful abilities that fundamentally change who you are—each modification is permanent

  • Enhanced night vision grants perfect darkness sight but makes light sources agonizing

  • Choose to embrace biological enhancement for strength, or preserve your humanity at the cost of power

  • Your reputation with townsfolk and availability of services depend on how visibly you've been transformed

SURVIVE & FIGHT

  • Master period-appropriate weapons from the Winchester 1893 Shotgun to the revolutionary C93 Borchardt pistol

  • Face Proto-Mutants—once humans transformed by Necrotech experiments, each with their own name, backstory, and unique characteristics

  • Employ stealth mechanics against enemies with acute hearing or enhanced vision

  • Physics-based interaction with a world that reacts to your choices—you remain vulnerable throughout

GOTHIC HORROR ATMOSPHERE

  • Experience body horror where every upgrade makes you more powerful and less human

  • Oppressive Victorian atmosphere realizes the nightmare of unchecked scientific progress

  • Uncover the truth behind mortality, intrigue, and the consequences of playing God

The tower offers power. The price is your humanity.
