After completing the final stage and returning to the first stage, the difficulty increases, but it will not increase again on subsequent completions.Bosses can never be defeated by waiting long enough until they self-destruct.The hit box which surrounds the Vic Viper is a bit larger in this version, making it more vulnerable to attacks.The Option Hunter does not appear in this version.This feature imitates the time limited Rotating Barrier power-up which originated in Gradius 2 for the MSX. For a limited period of time, all four Options will rotate around the Vic Viper before returning to the traditional snake-follow pattern, at which time Option will reappear on the power meter and can be activated again.

After you have activated four Options, you may choose the Option command again to activate the Option Rotation behavior.As a result, it is capable of sustaining five hits before depleting, as opposed to three in the arcade version. You can no longer choose between the Shields and the Force Field.Both the Laser and the Ripple can be selected twice, once to activate it, and a second time to improve its effectiveness. Both Laser abilities produce the Cyclone Laser effect, which is generated by rapidly drawing different chunks of the laser on every frame.Rather, a small circle indicated the position of the bomb, and the explosion it produces is much more effective at eliminating enemies than in the arcade game. The Spread Bomb ability does not actually produce missiles like the other Missile abilities do.The vocalization of Gofer is also accomplished through combinations of these words. They are simplified and the same for all four power type arrangements, but they are present. It is also the only Famicom conversion of a Gradius game to feature the vocal announcements of activated power-ups.( Gradius allowed two, and the Japanese version of Life Force allowed for three Options, shared between both players.) It is noteworthy that as the last Famicom conversion in the series, Gradius II finally allows players to activate four Options just like in the arcade.You can also choose from the classic Gradius shield, which protects the front part of the ship, or a larger Force Field, which is weaker but protects the entire ship. Amongst the new weapons are a Spread Bomb, which drops at an arc and causes a damaging explosion when it makes contact the 2-Way Missiles, which fires both upward and downward the Tail Gun, which will fire shots in front of and behind the Vic Viper and the Ripple Laser, which is less powerful than the standard laser but much wider. When you start the game or when you continue, you can choose your weapon array, which consists of four different arsenal variations. This ends with a battle against a gigantic mechanical spider, the Shadow Dancer, which is also completely invincible, and the only way to beat it is by dodging beneath its legs to find a safe spot until it leaves the screen. Later, the walls begin to shift and threaten to crush the ship if you’re not careful. The final stage is another base, which begins when the walls tear themselves apart and launch towards the Vic Viper.
