It's a great shark hunting simulation, rich in visuals, reallistic in the best sense, submersive sounds and ambience, full of submarine life with grat and extense and changing details from one scene to the other, equipment is rich and you can choose weapons from the light to the heavy (that exists in reality). Besides - if you don´t hunt - or in the moments of no shark action, the submarine world is vivid and full of details. You can swim and explore underwater as if real. Very amusing, is for hours. The only thing that isn't good is that the game has certain age and seems to have no sequels. It's a pity that so good games have poor marketing, in a world where the actions game dominate the stage with their direct and indirect marketing.
