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.

Well, uhm What did I just play? Feels like five year old wrote the script and his elder brother vibe-coded the game based on it. It lasts 3 hours and you don't want to buy it for full price. Actually, you most likely don't want to play it
Ein solides Spiel, leider hackt die Steurung manchmal und ein paar Gegnervarianten mehr wären cool gewesen. Hoffe das ein NG+ Modus mit dem neuen DLC kommt.
Look, I know I've got a "buy" recommendation, yet more cons than pros listed below. Bottom line: I wouldn't go full price, but I'd pick it up on sale if you can get 50% off or better. I'm really hoping the devs polish up some of the more annoying things - this game really has great potential. Definitely download the demo before you buy. Pros: * Visually fantastic - the textures really make a big impact. * The developers have done some genuinely interesting things in the game, such as having the main character break the 4th wall, and incorporate real-world elements to solve puzzles (such as QR codes). * The storyline is pretty interesting. Cons: * The AI voiceovers really kind of fall flat. I understand voice actors aren't cheap, but with the main character talking directly to you, it really takes away from the experience. * The combat system is atrocious, and movements are way sluggish. Definitely use a mouse and keyboard when you play; using a controller is just brutal. * The game holds your hand way too much and walks you step-by-step through some of the more interesting puzzles instead of giving you that little dopamine boost by letting you figure them out (see the QR code mention above).
Silly ending and too many crab things .
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...
no esta nada mal , por su precio merece la pena
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.
Game não deixa redefinir as teclas. Se comprei, tenho o direito de redefinir e escolher como quero cada comando. jogo descartado da minha lista, e seu conteúdo perde o sentido quando essa imposição acontece. Vou dar uma chance de ativarem o recurso para redefinir teclar.
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
Très sympas comme jeu malgré qu'il sois très court ! Environs 3 à 4h pour le terminer !
