Sonic Advance
Sonic Advance is the first Sonic game released on a Nintendo console, although Sega and Nintendo were well-known rivals in the console market in the 1990s. In Sonic Advance there are four playable characters and for the first time Amy Rose appears in a 2D title. The game borrows from the original Sonic the Hedgehog titles for the Sega Genesis, but with the post-Dreamcast art style for the characters that was introduced in Sonic Adventure. The game also includes multiplayer features and minigames. The title was also ported to the Nokia N-Gage under the title "SonicN".
Story
The game follows Sonic and his friends as they travel through different zones to stop Dr. Eggman from taking over the South Island. There are four playable characters in the game: Sonic, Tails, Knuckles and Amy. Each character has the same moves as in Sonic the Hedgehog 3 and Sonic & Knuckles, plus a melee attack. Each character has a special ability, such as Sonic's splice shield, Tails' flight, and Knuckles' gliding and climbing abilities. In her 2D playable debut, Amy can't perform the Spin Dash or go spherical while jumping like the others and must rely on her Piko Piko Hammer to defend herself, making her unique among the characters. The grind rails introduced in Sonic Adventure 2 also make their first 2D appearance. Sonic and Tails can also be used simultaneously during the story if you enter a cheat code in the character selection screen. When playing as both characters, the gameplay is similar to Sonic the Hedgehog 2: the player can only control Sonic, and a CPU-controlled Tails follows him.
