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.

cool game but it ran badly on my system. the dev really tried to help me but it seems it's a software issue dunno. leaving a positive review still for encouragement.
This game is honestly is good as a first indie game. It has plenty of challenge and silliness you would expect of a passion project. The game does use an assistant like AI that can help the player through difficult sections. The character's voice is very much AI but not too annoying. Most parts of the game is less hand holding then I expected especially the chase areas being rough but doable with some trial and error after learning where to go being easy to miss. One of my biggest complaints was getting stuck on random doorways near the ending portion of the game or during the beginning of the chase part hitting invisible geometry that stopped me dead in my tracks fives resulting in multiple deaths. Give it a shot if you feel it's worth your time and money. hopefully the creator only gets better as they make more dlc or games under their belts.

its a shame. the game looks great. But thats about it. game play is lame and combat is clunky
Mein erster Eindruck ist positiv, Die Grafik fällt vom ersten Moment an ins Auge, und die Atmosphäre ist wirklich gelungen, Man sollte nur im Hinterkopf behalten, dass es sich um ein Indie-Spiel handelt, also sollte man die Erwartungen nicht zu hoch setzen, Der Preis ist nicht schlecht, und bisher wirkt alles akzeptabel.
Я ожидал большего, на много большего. Говорилось про ИИ, то что ГГ будет общаться, юморить и тд, но я не чего из этого не увидел, сцены прописаны в заранее, кат сцены чуток топорные. Мне понравилась задумка самой игры, я считаю что разрабы определенно поработали над сюжетной составляющей...но.. ее прям п!зд!!" как мало, на вечер под пиво пойдет но не за такой ценник...
looks really good but it shame there is No support for left handed users....
I really don't understand the “Very Positive” rating. The advertised “AI” feels far more limited and scripted than the marketing suggests. That was already disappointing, but the bigger problem is that the game itself just isn't very good. Combat is clunky, movement and camera feel awkward, and the gameplay is shallow and restrictive. It feels more like a collection of ideas than a properly designed third-person sci-fi shooter. Nice visuals and atmosphere aren't enough to carry weak core gameplay. Not recommended in its current state.
no esta nada mal , por su precio merece la pena
Curto sem objetivos interessantes Quer LACRAR FALANDO DE CHE GUEVARA Não comprem
pour le moment je met un avis car les dev sont a l'écoute de nos soucis et de nos problèmes : le jeu a de beau graphique , le tuto façon PNJ qui décris les actions est génial , la customisation de notre tenue est simple : un très bon juste milieu :) juste bémol : le fait qu'on ne puisse pas configurer ses touches pour le moment : les développeurs se sont engagés a faire le correctif en même temps qu'un DLC en septembre : affaire a suivre
