Released exclusively for the Sega Game Gear in 1994, Sonic Triple Trouble--or Sonic & Tails 2 as it is called in Japan--is the sequel to Sonic Chaos, and is considered one of the best Sonic the Hedgehog games to appear on the handheld, mostly due to it being the closest in feel to its 16-Bit brothers on the Sega Genesis. It features the debut of Fang The Sniper (or Nack The Weasel as he was called in the English versions). Amusingly, on the American and European boxarts, Robotnik is depicted in a slightly modified version of his Adventures of Sonic the Hedgehog incarnation.
