About This Game

About This Game

O2 is a deep-sea horror exploration game where every breath matters.

You descend alone into the dark depths of an unexplored ocean. Armed with only a camera, a map, and a limited oxygen supply, your mission is simple: locate designated coordinates and capture photographic evidence of what lies below.

As you venture deeper, the ocean becomes increasingly hostile. Visibility fades, strange sounds echo through the darkness, and something unseen may be watching from beyond the reach of your light.

Manage your oxygen carefully as you navigate the abyss. Every photograph brings you closer to completing your mission, but also drains valuable resources needed to survive. Getting lost, running out of oxygen, or lingering too long in the darkness can turn a routine expedition into a desperate fight for survival.

Will you uncover the secrets hidden beneath the waves, or become another lost soul swallowed by the deep?
