Take part in Jacques Cousteau's Marine Conservation project in an attempt to study the diversity of marine life.
It's 1943 so the project's funds are under pressure because of the Second World War. Underwater photography is the only way to convince the government that new funds are needed, so put on your scuba gear and descent into the Deep Bleu for some neat snapshots.
Score points by taking photographs of marine life.
Finish before you run out of air.
Use the mouse to move around. Press Space to go into viewfinder mode, left click to make a photograph.
Points are awarded by size of the animal, position on the photograph, number of animals and rarity of the animal.
The deeper you are, the faster your air runs out.
