About Biolum


Biolum is a 30 minute narrative experience with light interactivity.

ABOUT BIOLUM : TAKE THE PLUNGE

Biolum brings us on an immersive mission into the deepest depths of the ocean to explore the abyss through the perspective of scientific researcher Rachel, voiced by Dominique Tipper (The Expanse). Rachel is guided by expedition leader Eva, a renowned marine scientist, played by Charlotte Rampling (Denis Villeneuve's Dune). As we discover the mysteries of this bioluminescent VR underworld, it becomes clear that this relationship is not as simple as we thought…

PARASITIC BIOLUMINESCENCE

Rachael discovers that a luminescent parasite is infecting the ocean flora and fauna. Glowing hybrid underwater oddities swim around us as Rachel and Eva try to understand the scientific meaning. The beautiful bioluminescence is wreaking havoc on the natural ecosystems. How could this have happened and what does it mean?

COSMIC WONDER OF THE GREAT UNKNOWN

In this VR story, nothing is as it seems. What’s beautiful very quickly reveals itself to be contagious, and perhaps more dangerous than ever imagined. As Rachel gets infected by these parasites, she faces a mesmeric fight for her mind and body. Inspired by the beauty of deep sea life, Biolum blurs the lines between biological truth and sci-fi and taps into existential themes and cosmic wonder of the great unknown.

  • Light interactivity woven throughout that advances the storyline and encourages you to become Rachel and immerse yourself into her exploration
  • Available in English, French, and Chinese,

✦ AI summary

Biolum is a brief 30-minute atmospheric experience that works best as a guided VR film rather than an interactive game, with players praising its immersive ambiance and creative sci-fi concepts but frustrated by the lack of player movement, underdeveloped characters, and minimal interactivity. The dialogue and voice acting improve as the experience progresses toward its psychedelic twist ending, though some find the early character dynamics cringey and the overall pacing too rushed to flesh out its interesting hard sci-fi ideas.

I expected more to be honest and the fact that you can't move around too much is truly unfortunate and nicked my experience a bit. HOWEVER, its definitely a good 30 min experience where your basically handheld but the Atmosphere is convincing and quite immersive nonetheless. The ending makes absolutely no sense but gotta respect getting turned into a squid for the love of the game. 7/10

A short 30min experience with underwhelming graphic textures and very cringey dialogue at the beginning. However, the dialogue (and voice-acting) improves once things get stressy. We don't get to know these characters so the drama feels unearned. The ideas are fun tho' unoriginal. I enjoyed the psychedelic 2001-Starchild tribute and 'twist' ending. The experience did make me wish this was a proper narrative game with exploration and slow-burn mystery. There's elements of decent hard sci-fi with the bioluminescence ideas, but there's not enough time here to flesh them out. A 50/50 recommendation. Maybe €4 is a bit steep, on sale it's worth a go if you enjoy movies like The Abyss. Just be aware there's no gameplay, no free movement. Just very minimal interactivity. Not worth a replay (well, rewatch) as the graphics aren't spectacular or deeply textured enough. For a one-off little VR experience it's fine. Quest Pro used: no issues.
