Insomnia Chapter One Build 23621022 (TENOKE)

About The Game

Insomnia Chapter One is a first-person psychological horror game centered around exploring an abandoned Arctic station and searching for answers to events that have long since spiraled out of control. As technician Ethan Miller, you find yourself at the Perseus base in the Kara Sea, where a routine work shift unexpectedly turns into a confrontation with the secrets of the past. The more rooms you open, the more disturbing the scene becomes. The station is filled with locked rooms, forgotten archives, and traces of the people who once worked there. The story unfolds through documents, personal notes, and objects left behind by the base's former inhabitants.

Each discovered fragment adds new questions and forces you to rethink what happened, gradually piecing together the overall picture of the disaster. The atmosphere of constant tension plays a key role. The creaking of metal, the hum of ventilation, flickering lighting, and the endless polar night create a feeling of complete isolation from the outside world. There's no way to solve the problem by force, so your only tool is your own observation skills and the ability to spot important details amidst the surrounding chaos.
