In addition to these changes, many power-ups in "Maverick Hunter X", such as the armor capsules, are relocated to different levels. The remake also has a few extras including an original video animation titled "The Day of Sigma" (which serves as a storyline prequel) and an unlockable mode to play through the game as the character Vile. Inafune implemented this mode to offer players a new perspective on the game through the eyes of a villain, feeling it would be "too obvious and boring" given an option to play as Zero.
