Editing Metroid II: Return of Samus

''Metroid II'''s gameplay set the stage for many of its sequels. New additions include crouching and aiming and shooting downwards in the air. Crouching is used by tapping down on the D-pad once. Tapping a second time while crouching will use the [[Morph Ball]]. Shooting downwards in the air is just like shooting upwards. The Spider Ball made it's first appearance in ''Metroid II''. It can stick to any wall in the game, provided it is not covered with spikes. The [[Space Jump]] made its debut in ''Metroid II''. Unlike the GBA games such as ''[[Metroid: Zero Mission]]'' and ''[[Metroid Fusion]]'', you can only engage the Space Jump just after Samus's spin jump peaks. ''Super Metroid'' shares this trait. The [[Spring Ball]] also made it's first appearence in ''Metroid II''. It enables the player to jump in Morph Ball form. Another difference from the original Metroid is the lack of color. The game is entirely monochrome, which ironically led to the redesign of the [[Varia Suit]]. The lack of color also forced the developers to make unique sprites for enemies.
