Hypoxia is an exciting and interactive fiction video game where YOUR DECISIONS will change the story.

SYNOPSIS



Since the Z gas appeared in the atmosphere 99 years ago, it is no longer possible to breath properly outside. As a result, almost all modern societies collapsed during the oxygen wars. On the Orbis Island, people survive thanks to a dome maintained and supplied with clean air by the Massive Air Company. However, the origins of the catastrophe remain unknown and the island suffers from a great political instability.

Carl Thanavan is a young scientist living in the Dome and determined to find the truth. As he accepts to host his sister’s friend Shaimaa, he doesn’t think that this decision will force him to put aside his ambitions and face his fear of the outside. On his journey, he will meet Olivia and take part unwillingly in the beginning of a revolution. He will then realize that the greatest threat for humanity was perhaps not the one he believed.

Hypoxia - One Last Breath is not a game, it's an e-book that's been dumped on Steam masquerading as a game. As a visual/interactive novel, this doesn't feature any notable gameplay, it's just a lot of clicking through badly written dialogue that would never have been accepted or published in print, which poses the question, "How did something this badly written end up on Steam?". When someone hoping to become an author is unable to get published in print, they spend $100 and dump their high school fan-fiction onto Steam, under the guise of a game. This is your typical high school anime club dropout fanfiction, as usual featuring the authors imaginary girlfriends/waifus and with a rather poor post apocalypse/sci fi theme, but as usual most of this fanfiction is just cringe. The only notable thing going on here is someone dug up a copy of Visual Novel Maker instead of using the usual Ren'Py construction kit to wrap around the highschool dropout writing. Visual novels/e-books are tedious at best... imagine the best novel you ever read, be that Hitchhikers Guide to the Galaxy or 2001: A Space Odyssey or Twilight (if you have terrible taste in literature), but then translate that t…

The writing feels like it's trying but it all just falls flat. Characters act very unnaturally/creepily according to the events and dialogue presented. With occasional dumbfounding lines leaving me stuck between confusion and cringing. It comes across as tone deaf and relies too much on outside sentiment for it's turning point scenes. I feel like it could have gone in a lot more interesting directions with the setting it presented.

Hypoxia - One Last Breath is a short science-fiction visual novel that combines a post-apocalyptic mystery with political tension, environmental catastrophe, and choice-driven storytelling. Developed by Nagi and Soulab and published by Hypoxia Studio, it takes a straightforward visual novel framework and builds its identity around a world where breathable air has become essential infrastructure rather than something humanity can take for granted. The result is a compact narrative experience aimed primarily at players who enjoy reading, making consequential decisions, and uncovering the history behind a damaged society. The setting provides the strongest hook. Decades after the appearance of a mysterious substance known as Z gas rendered the atmosphere dangerous, human civilization has been forced to adapt to a radically different way of life. The oxygen wars have already reshaped society, while the surviving population of Orbis Island lives beneath a protective Dome. Breathable air is maintained through technology controlled by the Massive Air Company, creating an interesting relationship between survival, corporate authority, science, and politics. Instead of treating the apocaly…

Игра 'Hypoxia - One Last Breath' – это напряженный, атмосферный подводный хоррор, который умело давит на игрока чувством клаустрофобии и постоянной нехватки кислорода. Визуально игра выглядит прекрасно, детализированное окружение и жуткие монстры создают гнетущую атмосферу. Геймплей строится на исследовании затопленной базы, решении головоломок и выживании в условиях ограниченных ресурсов. Нехватка кислорода – это не просто индикатор, а реальная угроза, заставляющая продумывать каждый шаг и искать пути пополнения запасов. Монстры, обитающие в глубинах, действительно пугают, и порой лучшим решением является тихое перемещение, а не прямой конфликт. Сюжет, хоть и не блещет оригинальностью, подан интересно и держит в напряжении до самого конца. Однако, игра не идеальна. Управление порой кажется немного неуклюжим, а некоторые головоломки – излишне запутанными. Тем не менее, атмосферность и напряженность с лихвой компенсируют эти недостатки. Любителям подводных хорроров и игр на выживание определенно стоит попробовать. Это уникальный и запоминающийся опыт.
