About the Game

Dive into O3 - Hollow Descent, a bullet-hell roguelike shooter set in a surreal universe inspired by the haunting art of H.R. Giger and Zdzisław Beksiński. As a lone astronaut stranded on a hostile planet, navigate ever-changing rooms filled with deadly traps and malevolent creatures. Uncover ancient ruins, confront intelligent life forms, and unravel the mysteries that lie within.

The depths shift and reshape. Traverse ever-changing corridors, evade deadly traps, and fight to escape.

The dungeon is relentless. Dash through waves of destruction, unleash devastating weapons, and carve a path through the unknown.

Uncover the unseen and step beyond the veil. Reveal hidden rooms, open abyssal chests, and exchange remnants for powerful upgrades.
