Reef Shot

Reef Shot is an underwater adventure game that takes the player on an unusual voyage to the Pacific and gives him an opportunity to explore the world of marine life and discover sunken Mayan ruins and the end of the world prophecy.
The player starts a photo-diving expedition along the coast of Robinson Crusoe Island, which becomes a mysterious underwater adventure. The game combines a navigation system in 3D space and mechanics of taking photos in realistic underwater scenery. It offers an engaging experience based on various tasks and ocean environment, supported by high quality soundtrack.

Reef Shot features 3 types of camera:

Basic

The simplest camera to help you learn taking photos. Doesn’t require focusing or centering but can’t take perfect pictures. Good for shooting quick photos at the beginning of your underwater adventure.

Autofocus

A more advanced camera introduced later in the game that allows you to take better photos but requires more skill and patience. Focuses automatically, but takes a moment to do so. The right tool for a pro photographer.

Manual focus

The most difficult to handle, but also the most rewarding camera that requires you to focus photos yourself. The good news is that it allows you to take perfect underwater photos and pass the most difficult tasks.

photos can also be saved on the PC hard disk and shared with friends outside of the game.
