The story behind Drowned God takes place under the notion that the human race was genetically engineered by god-like aliens that guided humankind through history by nudging civilization forward with certain artifacts of power. Four of those artifacts (The Ark of the Covenant, The Philosopher's Stone, The Rod of Osiris, and the Holy Grail) are now lost and they are the key to unlocking a series of mysteries that somehow tie up practically every conspiracy theory from the Knights Templar to the Illuminati.
It is up to the player to gather these artifacts and solve the mysteries as they are sent through time and space from an alternate dimension, reminiscent of earth.
The gameplay tends to set the pace for the development of the surreal storyline. Within every new location players will confront logic puzzles in the vein of The 7th Guest, which will give them access to new locations, secrets, etc. The interface itself is more reminiscent of the Myst games, where players move through pre-rendered "slideshows" and click on objects to interact with them.
