In this version, the level structure had been altered, many of the enemy bosses were removed, and Stage 4 of the original game (the Air Battle level) was removed. A strafing ability was included to compensate for the absence of rotation in both top-view stages, and a password feature was added. The player no longer has the ability to hold two weapons, but can still carry and use Bombs with the Select button. All the weapons from the original SNES game are featured except for the Laser Gun. The game features Super Game Boy support, which provides a custom color scheme and enhanced sound effects.
