Sega built its 1992 holiday season around Sonic the Hedgehog 2, launching it worldwide with a marketing push dubbed "Sonic 2sday." Developed largely in California at Sega Technical Institute by a team including Yuji Naka, it introduced Tails as a sidekick and made the series faster and bigger.
The spin dash is the key addition: hold Down and press jump to rev up and blast off from a standstill, which removes the need for long run-ups. Zones such as Chemical Plant, Casino Night and Metropolis showcase loops, pinball bumpers and twisting tubes, and Sonic can become Super Sonic after collecting all seven Chaos Emeralds in the three-dimensional half-pipe special stages. A second controller can take over Tails, or two players can race in a split-screen mode. It became one of the Genesis's best-selling games, and for many players it defines the series.
Tips for Sonic the Hedgehog 2
Enter special stages by touching a checkpoint with at least 50 rings; that is how you collect Chaos Emeralds.
In Metropolis, keep moving and watch for enemies that leap or shoot, as the zone is notoriously hard.
