The second Metroid game ever made introduces a plethora of new abilities and an improved control system, but being released on the Game Boy resulted in a loss of color for the series as it took its first and only steps into the realm of black and white. More linear than its predacessor Samus Aran is sent on a mission by the Galactic Federation to exterminate all of the Metroid species on the planet SR388.
