About

A third-person survival horror action game set in dark, atmospheric underground environments, blending psychological suspense with intense combat.
The story follows Adam, a former special forces operative assigned a top-secret mission: investigate a supposedly abandoned underground bio-research facility and extract evidence proving the government’s involvement in funding a viral development program—one that spiraled out of control and killed thousands.
What begins as a simple data retrieval job quickly turns into a dangerous search for answers. Most of the facility’s personnel are dead—casualties of brutal emergency protocols. Two scientists are missing, and Adam must track them through dark, hazardous corridors and storm-drain tunnels.
As Adam follows their trail, unsettling signs and unexplained events make him question the true nature of his mission—and his own connection to the facility.
Estimated playtime: approximately 4 hours for a standard playthrough.

Det är ett bra spel, Jag gillar atmosfären och ger det 7.5/10
за 20 минут понял что игра пиздатая
bon jeu, hâte de voir la suite de l'aventure.
Gayet güzel bir oyun hikayesi başaralı ve türkçe dil desteğide bulunuyor
Totally worth it! A mix of Metro/Dead space feeling. Sure the character is a bit clunky but the story line and overall gameplay is just fine. Remember this is a indie game. Good job developers :)
its a shame. the game looks great. But thats about it. game play is lame and combat is clunky
J'ai vraiment aimé ce jeu. L'ambiance est super immersive et j'ai passé un très bon moment dessus. C'est clairement un jeu que je recommande si vous aimez les jeux d'horreur. Hâte de voir les prochains jeux des développeurs !
понравилась фишка с ИИшкой. то,как персонаж обращается напрямую к игроку,комментирует его действия - забавляет. немного утомляет работать электриком, ходя по маршруту от точки А до точки В,но для меня это не критически. единственный минус - это боёвка. если с автомата можно принаравиться,то ближний бой подвёл. не исключено,что это просто я сильно косая) задумка хорошая,визуал впечетляющий,да и моментами заставляет напрягаться от того как всё тихо и спокойно,а ты так и ждёшь пока на тебя выпрыгнет какая-то tварь. так что игру советую. повелась изначально на ломание четвёртой стены и визуал,не разочаровалась очень жду DLC, и огромное уважение к разработчику,который следит за сообществом своей игры:) очень приятно удивило
Довольно неплохая игра! С неплохим сюжетом! В игре есть небольшая просадка по ближнему бою, Но в целом игра хорошая! Рекомендую! Этим летом должно выйти бесплатное DLC к игре. Посмотрим что нас там ждёт )
this is just bad bad i have every thing to max and i have never seen this bad of games like i have just had a horrible experience it looks like dog poop like the walls look like garbage the game should not be out in this state like why can i change my graphics when it does nothing like it crashed and the loading to get in the game two long
