It is the seventh chronological installment in the Sonic the Hedgehog series. It follows the protagonist team of Sonic the Hedgehog, Knuckles the Echidna, and Miles "Tails" Prower and the antagonist team of Doctor Eggman, Shadow the Hedgehog, and Rouge the Bat and their attempt to work together in order to save the world from destruction.

Battle received mixed to positive reviews from critics, who praised its new features and ability to use the GameBoy Advance link cable, however, dismissed its poor control, camera, and lack of variety compared to other GameCube titles. Despite its mixed reception, Battle was a commercial success, selling more than 1 million copies worldwide and becoming the tenth best-selling Nintendo GameCube game of all time.
Gameplay
ــــــــــــــــــــــــــــــــــــــــــــــــــ
Sonic Adventure 2 uses 3D graphics in addition to scrolling backgrounds. The game follows the same basic principles of previous games in the series. Within most stages are rings, which will protect the player from dying, so long as at least one is held by the player. The Tails and Doctor Eggman stages are an exception, as they employ a health bar which is reloaded by gathering rings. Item capsules are also located within the stages, which provide the player bonuses. Each character has obtainable power-ups which grant them new abilities, such as the ability to destroy metal boxes or play mystical melodies.
Single-player
The single player mode can be played between two parallel story lines, the "Hero" story mode and the "Dark" story mode. The player has the option of advancing in either story at any time. The "Hero" story features Sonic, Knuckles, Tails, while the "Dark" story features Shadow, Rouge, and Dr. Eggman. Each dark character plays similarly to its corresponding hero character, respectively. Levels advance in the same order for both story lines.

Levels featuring Sonic or Shadow are regular platform levels, designed in much the same way as Sonic's levels in Sonic Adventure.[3] The player's primary objective is to reach the end of the level. Levels with Tails or Dr. Eggman are based on shooting, allowing the player to control a mechanized robot walker and shoot their way to the end, reminiscent of E-102 Gamma's stages in Sonic Adventure. The Knuckles and Rouge levels are based on hunting, with the characters scouring the levels for three keys, usually shards of the Master Emerald, much like Knuckles' levels in Sonic Adventure. Interspersed among the levels are various bosses, which one specific character must fight. The main story line can only be completed by finishing both the "Hero" and "Dark" story lines. When the main story line is completed, an extra "Final" story mode is introduced in which the player must use all 6 characters back-to-back to achieve the true ending.
At the end of each stage, the player is given a score based on the number or rings collected and time spent within the level. The more rings collected and the less time spent, the higher the player's score is. The player is also given a performance ranking, a letter grade that is either A, B, C, D, or E, with A being the highest and E being the lowest. Regardless of any other factors, an A Rank is automatically awarded if the player completes any score-ranked mission with all of the level's rings in the player's possession.
Within Action Stages, players must collect rings and defeat enemies, with a timer counting the time spent within the level. Five missions are assigned to each Action Stage; in order to access the next mission, the player must successfully complete each previous mission. In order from first to last, the missions are to complete the level, collect 100 rings, find a "lost Chao" using the Mystic Melody, finish within a time limit, and complete a "Hard mode" version of the Action Stage. Special moves are acquired by collecting a certain number of rings; these moves are also seen in the final bosses of the Hero and Dark stories.
Emblems (180 total) are also given throughout the game. In order to gain all 180 Emblems, players must defeat every mission within every stage and achieve an A rank in all stages and missions. After collecting all 180 Emblems the player unlocks the 3D Green Hill level, a remake of Green Hill Zone from the original Sonic the Hedgehog game.
