O2

O2 is a deep-sea horror exploration game in which you descend alone into an unexplored ocean. Carrying a camera, a map and a limited oxygen supply, you must reach designated coordinates and photograph what lies below.

Explore the abyss

As you go deeper, visibility fades and strange sounds echo through the darkness. Something unseen may be watching beyond the reach of your light. You navigate with a map and compass while exploring the underwater world and uncovering its mysteries.

Manage your oxygen

Taking photographs advances your objectives but uses oxygen you need to survive. You must manage your supply as you navigate: getting lost, running out of oxygen or lingering too long in the darkness can turn an expedition into a fight for survival.
