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.

diversão garantida, gráfico excelente, jogabilidade boa. Esperando a DLC para mais diversão, jogo um pouco curto. Recomendo.
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
OK the game was really good, but that AI was annoy, i do hope you make it to were we can shut it up. the game was good as the shooting and the environment. my only complaint is that ♥♥♥♥♥♥♥ AI
Ich will mehr mehr mehr mehr mehr :) MEEEHHHHHHRRRRRRRR
It's just so bad. Clumsy animations, some sort of AI generated English voiceover and genuinely ridiculous story would make you think you're playing some sort of a parody game, if only it didn't pretend to be serious. The only advantage is that it's made on UE5, but even that doesn't make the in game poor quality models signifficantly better. 2 trash cans out of 10
Игра интересная и с необычная с подходом с ии, жду когда выйдет DLC
Необычный формат геймплея, зайдет тем, кто ищет чего-то необычного
Curto sem objetivos interessantes Quer LACRAR FALANDO DE CHE GUEVARA Não comprem
Just bad, bad voice, bad controls, just a bad play experience.
игра вполне неплохая если вы богатый - чисто ради развлекухи на вечер купить можно но цена слишком большая анимации - топорные и кривые (и боевые и просто анимации взаимодействия с окружением будто в блендере за 5 минут сделаны) главная фишка - живой гг реализована так себе ии тут нету, скрипта за скриптой. Но гг ломает 4 стену, это правда, и это прикольно графика мое почтение, респект Unreal Engine и работе разрабов интерфейс из бесплатных ассетов собранный, выглядит колхозно и неприятненько боевка - ужасная, худшая сторона игры. Оружие не чуствуется вообще никак, враги жирные и однотипные. Только боссы могут удивить, бой с боссом на вагонетке (можете увидеть ее ниже в описании к игре) сделан очень хорошо, пафоса нагнали знатно - но не кринжа а также мап дизайн - застрял намертво 4 раза пока проходил, не круто вообщем - если есть лишние денежки, купить можно. А, да оптимизация - фифти фифти, даже на 4090 бывают приколы
