Dragon Ball Z: The Legacy of Goku II is a 2D sci-fi fantasy action-RPG developed by Webfoot and published by Atari for the Game Boy Advance in North America (on June 17, 2003) and Europe (on August 1, 2003). It was later released in Japan (as Dragon Ball Z: The Legacy of Goku II - International) by Banpresto on July 23, 2004.
It is the sequel to Dragon Ball Z: The Legacy of Goku, following an adaptation of the "Android Saga" parts of the Dragon Ball Z storyline. As Goku is returning home following the destruction of Namek, players control his son Gohan as he and the other Z Warriors prepare for the arrival of powerful androids created by mad scientist Dr. Gero (as foretold by a mysterious warrior known as Trunks). Along with a more non-linear game progression, the game features multiple playable characters (including Goku, Gohan, Trunks, and Goku's former rivals Piccolo and Vegeta), each with their own techniques.
The game later recieved a sequel, titled Dragon Ball Z: Buu's Fury, rounding out the "Legacy of Goku" game trilogy.
The game features a number of new features; such as a more non-linear progression, the ability to control other characters in the Dragon Ball Z series, side quests, and more techniques to use during combat.
The story progression is more non-linear than the original game, the player can step outside of the story and explore other areas that the game contains. The new feature in the game is the ability to travel from area to area via flying - the game has a 3D section where the player can fly in any direction once the player leaves the area that he or she is in. Some of the areas are some of the famous location that was feature in the anime series, like Kami's lookout tower, Goku's home, and Capsule Corp.
One of the most noticeable feature in the game is to control other characters. When the story progresses, the game will move on to other character. For example, Goku will be affected by virus at one point in the game; once that happens, the player will be in control of Vegeta. Later in the game the player will have the ability to take control of any one of the characters at any time.
The combat in the game is very similar to the previous game, but new techniques are presented. One of them is the ability to turn into a super-saiyan, that was only something that was introduction at the end of the last game. In super-saiyan mode, the character will temporally have faster speed and strength, but once the energy meter depletes, the super-saiyan powers goes away. All of the characters have their own techniques that differ from each other.
The game also features items that can be use. One of them is "senzu beans" - that it uses for restoring health. And a scouter that is uses for scanning any living thing (Human, animal, or alien). By pressing one of the shoulder buttons, the player will enter a grid with all the living things that's surrounding the player in it and can scan it by moving a reticle towards it. What the player will scan is the living thing's power and it's bio. The game also features 25 collectable gold capsules, scattered throughout the Dragon Ball world, as well as other side quests, which eventually lead up to a hidden boss in the game.
