Sunken Gelnika is a bonus dungeon in Final Fantasy VII. It lies on the Bottom of the Sea to the south of Costa del Sol. Accessible first in "Toward the Sea of Stars", plane can only be accessed after the player has acquired a submarine.
The Gelnika holds some of the game's most difficult randomly encountered enemies, and also some excellent treasures. It can be visited at any time after obtaining the submarine; however, normally, if it is visited after "Mako Cannon Rampage", the boss battle against the Turks will not take place.
Layout[]

Hallway[]
- Entrance
The entrance is entered from the Bottom of the Sea world map. A ladder descends into the Gelnika. At the top of the screen is a door leading to the Research Room. A save point sits next to this door. On the far-left is a door leading to a second Hallway. By this door is a chest containing the Heaven's Cloud weapon. There are no encounters fought in this room.
- Hallway
Can be entered from the Entrance through a door at the bottom of the screen on the right hand side. At the top of the screen is a door that leads to the Cargo Room. If the player comes here before venturing to Midgar for "Mako Cannon Rampage", Reno and Rude can be found here and a boss battle will occur. If the player skips the battle with the Turks bypassing the walkmesh line to trigger the scripted scene from playing out during "Mako Cannon Rampage", the Turks will still appear in the Gelnika thereafter.
Research Room[]
Research Room.
The Research Room can be entered from a door from the south which links it to the Entrance. Straight ahead by the left wall is a slope that leads up to a raised platform. At the end of this is a chest containing a Megalixir. Heading right from the entrance will lead to a box containing the Escort Guard armor.
In the top-left corner of the lower-level of the room is the Conformer, the ultimate weapon for Yuffie; and in the top-right corner is the Double Cut Materia. Though the Materia is pink in the field, the Double Cut Materia is a yellow Command Materia. If the chest containing the Megalixir is opened, the Double Cut Materia is hidden to the camera by the chest's lid. The Materia is on the lower floor whereas the chest is on the upper floor.
Cargo Room[]
Cargo Room.
The Cargo Room is entered from the Hallway. Straight ahead is a chest containing a Megalixir. Straight ahead and the whole way along the right leads to a chest containing the Spirit Lance weapon. A staircase leads to a lower level. On the right-hand side, the Hades Materia can be found in-between some wreckage.
In the bottom-right of the screen is a chest containing the Highwind manual to learn Cid's ultimate Limit Break. In the bottom-left of the screen is a chest containing the Outsider weapon.
Quests[]
The Sunken Gelnika is accessible anytime after "Clash in the Deep Sea", but is entirely optional.
Stat maxing[]
Every enemy except the Turks in the sunken Gelnika can be morphed into stat plus items, allowing the player to max out every stat. Appropriately enough, Yuffie's ultimate weapon, the Conformer, which can morph enemies while dealing 100% damage instead of 10%, is also found on the sunken Gelnika.
Level grinding[]
If the player is too weak to survive, obtaining Knights of the Round and pairing it with a Sneak Attack Materia may make the area more hospitable. As Sunken Gelnika is accessible before the W-Item Materia, which can be used for the W-Item duplication bug, it is advisable to buy Tents and stay near the door to the room with the save point, as no enemies are encountered there. Since Unknown yield a lot of gil, it is easy to buy a lot of Tents, but as sunken Gelnika has no shop, players have to leave to go to the nearby Corel to buy Tents if they run out.

Behind the scenes[]
Occasionally, Emerald Weapon will appear just in front of the plane, forcing players to go around it or surface if they want to avoid fighting it. It is possible to collide with the Weapon at such an angle that the submarine will fly right into the Gelnika, triggering the player's entrance to it rather than a battle with the Weapon.
