About the game
Biolum is a short, thirty-minute VR narrative experience with a science-fiction bent, sending players diving into uncharted ocean depths to discover a world full of bioluminescent creatures. It soon becomes clear that things aren't quite what they seem down there. IKO, Reynard Films, and Prefrontal Cortex worked on the project together, with Astrea publishing it in 2021.
