A secret conversation can be witnessed in Metroid Fusion. To hear it, Samus must perform a difficult series of Shinesparks in Sector 4 after she has opened Level 4 security doors, but before she obtains the Diffusion Missiles.

Stick to the low ground and fire charged beam shots directly at the SA-X to destroy it. Your beam must be fully charged to damage it. As it approaches, Space Jump over the SA-X to the other side of the floor while charging your beam, and release the shot when you land.

In order to damage the SA-X, Samus must once again use the Charge Beam. Once the mutated form is defeated, the SA-X reverts to a Core-X and attempts to both collide onto Samus and hit her with the Ice Beam. Once Samus defeats the Core-X, the X inside retreats out of reach, phasing through a wall and escaping.

The in-game menu. The in-game debug menu is accessed after loading from the SECTION option by opening the map and pressing R, and functions similar to the one in Fusion.
