The G.G. Shinobi II: The Silent Fury (ザ・GG 忍 II?) is a side-scrolling action game by Sega released for the Game Gear in 1992. It is the sequel to The G.G. Shinobi, an off-shoot of the Shinobi series created for Sega's portable platform. The player controls Joe Musashi as he rendezvous with his ninja allies from the previous game, giving the player access to different characters with unique abilities as the game progresses.
Joe Musashi has to rescue the four fellow ninja and retrieve their corresponding Elemental Crystals, before the final showdown against the evil Black Ninja in his castle.
The player begins the game as Joe Musashi (the Red Ninja), whose mission is to retrieve five elemental crystals that were stolen by the enemy and spread across different locations. Similarly to the original G.G. Shinobi, the first four stages can be played in any order and after defeating the boss of each stage, Musashi will be joined by one of his allies, allowing the player to control them as well. Some of the ninjas' abilities are different from those in the previous game. Depending on the stage, the player must use a specific ninja's ability in order to reach the location of the crystal. As a result, some of the stages must be played more than once if the player doesn't have the necessary character yet. When the first four crystals are all gathered, the player gains access to the enemy's main base, where the fifth crystal is being held by the final boss.
In 2011, Complex.com ranked it as the 18th greatest handheld game of all time, adding "it was definitely one of the reasons we were Sega fanboys/fangirls back in the day. Why get a Game Boy when you could get THIS?"
