Sonic The Hedgehog 2 Classic is a 2D side-scrolling platformer game developed and published by SEGA. It is a remastered version of the classic game that was originally released in 1992 for the Sega Genesis console. The game was released for mobile devices in 2017 and is available on both iOS and Android. The game follows the adventures of Sonic the Hedgehog and his sidekick Tails as they race through various levels to defeat the evil Dr. Eggman. The game features eight zones, each with three acts and a boss battle at the end. The zones are filled with obstacles, enemies, and power-ups that the player must navigate through in order to progress. The gameplay is simple yet addictive. The player controls Sonic or Tails as they run, jump, and spin their way through each level. The objective is to reach the end of the level as quickly as possible while collecting rings and avoiding obstacles and enemies. Rings act as the player's health, and if they are hit by an enemy without any rings, they lose a life. The game also features a time attack mode where the player can compete with other players from around the world to see who can complete a level the fastest. There are also leaderboards where players can compare their scores and times with others. One of the unique features of Sonic The Hedgehog 2 Classic is the inclusion of Tails as a playable character. Tails can fly and swim, which gives him an advantage over Sonic in certain situations. However, he is also slower than Sonic, so players must choose which character to use depending on the level and their personal preferences. Sonic The Hedgehog 2 Classic is a fantastic game that is perfect for fans of the original game or newcomers to the series. The gameplay is simple yet challenging, and the inclusion of Tails adds a new dimension to the game. The graphics and sound design are faithful to the original, making it a great nostalgic experience for fans of the series. The game is also free to play, although there are in-app purchases for additional lives and characters. However, these are not necessary to enjoy the game, and players can complete the game without spending any money.
