Deep-Sea Submarine Stage

"Obliterate the battleship!"

- Stage tagline

Deep-Sea Submarine Stage (深海潜水艦ステージ) is Tidal Whale's stage in Mega Man X5. It is an underwater historical site located in the North Atlantic Ocean.

Description
The stage is a prolonged underwater fight against the battle submarine U-555. It is mostly an auto-scroller, with various parts of U-555 such as its head, tail, or back pushing the screen along. During this time, the player is free to attack U-555 to stop its laser attacks or weaken it - then, at certain moments a health bar will appear and the player will have to fight U-555 before it continues moving. There is also a brief sunken ship segment in the middle of the level, wherein the stage is no longer underwater. After finally disposing of U-555 for good (the third sub-boss fight against it), access is granted to Tidal Whale's arena.

Enemies

 * Dejira
 * Dejira GR
 * Gulpfer R

Items

 * Life Up: During the sunken ship segment, there is eventually a drop. Instead of going down, go up (avoiding the spiked walls with Gaea Armor or Falcon Armor) and head left to find the Life Up.
 * Falcon Armor's Body Program: After falling down said drop in the sunken ship, the capsule will be in plain sight behind a wall. Use Goo Shaver to reach the bomb under the wall and grant access.
