Sector 4 conversation

The Secret Message is an easter egg found in Metroid Fusion. The player can attempt to access it by performing a difficult series of Shinesparks in Sector 4 to access a navigation room after opening level 4 security hatches, but before obtaining the Diffusion Missile. This process is very difficult and it is could potentially be a form of sequence breaking. However, since the message is in the game, developers obviously knew that players could do this, so Adam directs Samus to get the Diffusion Missiles immediately after this to prevent sequence breaking. In the message, Adam is impressed by Samus' technique to skip the Diffusion Missiles. A shadowy figure working for the Galactic Federation appears to congratulate her as well and wants to reward her by telling Samus about the Federation's secret Metroid breeding program. However, Adam states this is unwise, and prevents him from doing so.
