Deep Fear

Deep Fear is a 1998 Survival Horror game for Sega Saturn, known for being the last Saturn game to reach Europe.

The player controls John Mayor from the ERS, a sort of civilian mercenary group specialised in rescues, stationed in the Big Table, an underwater army base. As the game begins, the submarine Sea Fox delivers to the base a capsule who recently fell out from space. Suddenly, the submarine inexplicably crashes, opening all his nuclear missiles hatches. John manages to go in the wreck and deactivate the hatches, but something came from the Sea Fox to the Big Table...

A Resident Evil knock-off who is surprisingly good. Even though it's too easy (there are many places where you can reload your weapons' ammo and health sprays as often as you wish) and isn't really scary, it has an excellent story and atmosphere, original gameplay ideas (being in an underwater base, you'll have to keep an eye on the oxygen levels of the zones and go through flooded rooms; you can also affect an item to the Z button, allowing you to use it without going through the menus), and the music is from Kenji Kawai.

The Tropes associated with this game are:

 * Bittersweet Ending:
 * Body Horror: Oh so very much...
 * Camp: Dubois Amalric
 * Dead Little Sister: Dead fiancee, actually.
 * Do Not Run With a Gun: Averted. John can walk and run even with his gun ready to shoot. A great improvement over Resident Evil.
 * Load Bearing Boss: THREE OF THEM!!
 * No Export for You: Barely averted. See above.
 * Oxygen Meter: Each room holds a limited oxygen level represented by a time counter, which goes down faster if you use your weapons. You also have the rebreather, a tiny oxygen bottle you use in the rooms without air (time counter to zero, flooded, or filled with poison) which has a meter, making it a straighter example. Luckily, the save points allow you to reload the rebreather and all the rooms of the area you're currently in.
 * Rescue Romance: Between John and Gena.
 * Selective Gravity: In the flooded rooms, John and the monsters stay on floor, walk and run like if it was a normal situation (Even though in the first flooded room you come across in the game, you see a corpse floating between two waters)!
