Sonic Adventure 2 (2001)
Sonic Adventure 2 follows the basic principles of previous games in the Sonic Adventure series: at levels, you need to collect rings to protect the hero from death and gaining additional lives.
The action takes place on a planet similar to Earth. Like Earth, the planet is inhabited by people of different nationalities, but most of them live in cities. Deserts and jungles are poorly populated and there are only Eggman robots or the base of the organization "G.U.N."
Another location of the game is the space colony of the ARC, it was built 50 years before the main action of Sonic Adventure 2 for conducting experiments to create a "higher form of life", not subject to any diseases and old age. The project was led by Professor Gerald Robotnik, who had an incurablely ill granddaughter Maria. But soon the colony was closed forever because of fears of the state that the scientist wants to capture the world with the help of his inventions. After 50 years, Gerald's grandson, Dr. Eggman, uses the ARC to completely destroy the planet.
In Sonic Adventure 2 there are six main game characters:
Sonic the Hedgehog - the main character of the team of heroes. Sworn enemy of Dr. Eggman.
Miles Prower or Tails is Sonic's friend, prodigy in mechanics and aircraft building. Manages the Tornado, which can be turned into a car.
Knuckles the Echidna is the keeper of the mysterious stone - the Master of the Emerald. It comes from the ancient clan of echidna.
Doctor Eggman, real name Dr. Ivo Robotnik is the main villain of the game, the grandson of Professor Gerald Robotnik.
Shadow the Hedgehog - the highest form of life, created in the space colony of the ARC 50 years ago. He avenges humanity for the death of his best friend Mary.
Rouge the Bat is a treasure hunter and a government agent of G.U.N. Helps Dr. Eggman in search of Chaos Emeralds to restore the Eclipse cannon.
Chao and Chao Gardens
Little Chao creatures live separately from people in Chao World. Like people, Chao can grow and develop.
The player finds Chao in the gardens, where they begin their life cycle with the eggs. After birth, they crawl and can not swim.
The player must feed Chao with nuts falling from the trees.
To increase the characteristics and improve certain abilities, the player gives the animals specifically for the mutation capsules "Chao Drives" or small animals that can be found on the levels.
After a while, Chao pupate and evolve. After growth the pet can become Hero Chao or Dark Chao. Then the chao turns into a higher form of life: it can turn into Chaos Chao, Devil Chao or angelic Angel Chao.
The Chao Garden exists to check Chao's characteristics and health, and also so that they can learn new abilities.
Light and dark history
The plot of the game is divided into "light" and "dark" stories. The "light" story includes Sonic, Tails and Knuckles, while the "Dark" story includes Shadow, Eggman and Rouge.
After passing two storylines, "Cannon's Core" opens where you need to play for heroes and villains - to complete the game you need to go through the game for both "light" and "dark".
