About This Game
Explore our planet's ocean to discover animals, plants, and shipwrecks. Take photographs to document your findings and sell them to fund upgrades to your submarine.
Detailed Description
Have you ever wanted to explore the depths of the ocean?
In this submarine simulator, realistic ocean floor bathymetry is home to a range of flora and fauna. Take photographs and sell them to upgrade your submarine - the more species in your photos, the more they are worth!
Observe and record different varieties of animals in your catalogue - an albino blue whale, a giant Japanese spidercrab, and many more...
PLEASE NOTE: I have not yet uploaded a version of TethyScope that works for older machines that do not support Vulkan (modern graphics API). I believe computers newer than 2013 should have support for Vulkan. If you purchase TethyScope and are unable to play it due to this issue, please contact me for a full refund.
