Sonic the Hedgehog 2 is the second outing of Sonic on the Sega Mega Drive/Genesis and the first game to feature Miles "Tails" Prower. The game has longer levels, more levels, and a faster pace than its predecessor, Sonic the Hedgehog. The essential plot is that Robotnik is creating a spaceship of doom, the Death Egg. Sonic and Tails must stop this superweapon.

Numerous new cultural references can be found that have become a staple of the series. The Death Egg is a nod to Star Wars' Death Star. The seventh emerald is an analog to the search done in the Chinese fable The Golden Warriror (or Saiyuki), as illustrated by the seven dragonballs in the Dragon Ball series. In it, the hero Son Gokuu (aka The Monkey King) fights hordes of diabolical villains, generally in order to protect the universe by keeping their hands far away from the seven dragonballs; when they are all kept in the same place at the same time, and after a brief summonning, a giant Dragon-like creature (known as Sheng Long) grants the summoner a wish, whichever this might be. The hero and other few characters are saiyajin, an alien warrior race that, in certain situations, can explode in a burst of energy, transforming into the legendary Super Saiyajins. Super Sonic is also like a Super Saiyajin both in the graphical design and concept.

Sonic 2 introduced the spindash move to the Sonic series. It was also the first game to feature 3D special stages, in the form of a half-pipe filled with rings and bombs. These stages are accessed from hitting a checkpoint with 50 or more rings. Unfortunately for some, Sonic 2 removed the bonus points available from jumping at the end level sign, which could be done in Sonic 1.

Sonic 2 had a worldwide release date, which was uncommon at the time. November 24, 1992, was dubbed Sonic 2sday, and the game was released across all markets. This is referenced in the game by the order in which you need to play the sound effects to activate the debug mode. It was included as a pack-in for the Mega Drive 2. A enhanced Sega CD port called Sonic the Hedgehog 2 CD was planned but ultimately cancelled.

The Sonic 2 Beta, found by Simon Wai, is famous for its deleted levels. Another much earlier beta was found by drx and looks similar to the one featured on the tv show Nick Arcade. This was followed later by the discovery and release of five more betas, named Beta 4, Beta 5, Beta 6, Beta 7, and Beta 8. These ones seem to be very similar to the final version.

Scoring

Hitting bumpers: 10 points for each of the first ten hits on any given bumper; after that no more points can be gained from that bumper

Hitting enemies: (a chain refers to all enemies destroyed until the next time Sonic lands on some form of ground)

  • First enemy in a chain = 100
  • Second enemy in a chain = 200
  • Third enemy in a chain = 500
  • Fourth through 15th enemies in a chain = 1000 each
  • 16th and all subsequent enemies in a chain = 10,000 each

Destroying a Dr. Eggman boss robot: 1000 points

Ring bonus at end of level: 100 points for each ring held

Perfect Bonus at end of level: The game stores a list of how many rings are present in each level. Each time you get a lone ring, the game subtracts one from this value (debug rings and Super Ring boxes do not affect this counter). If this value is 0 when you pass the endpost, you receive a 50,000 point bonus. As long as you get all the actual rings in the level, you don't need to get any Super Ring boxes to receive this bonus--you can even get hit and still be eligible.

Time bonus at end of level:

  • Game clock reads 0:29 or less = 50,000
  • Game clock reads 0:30 to 0:44 = 10,000
  • Game clock reads 0:45 to 0:59 = 5000
  • Game clock reads 1:00 to 1:29 = 4000
  • Game clock reads 1:30 to 1:59 = 3000
  • Game clock reads 2:00 to 2:59 = 2000
  • Game clock reads 3:00 to 3:59 = 1000
  • Game clock reads 4:00 to 4:59 = 500
  • Game clock reads 5:00 or more = 0

Special scoring in Casino Night Zone:

  • There are certain slots which aren't connected to Slot Machines. If you enter one of these, you don't trigger any machine spins indeed, but instead you get 8x100 points. (At one point in act 2, there are five such slots placed directly above one another, so landing in one triggers the rest in sequence for 4000 points.)
  • There are also green, yellow, and red bumpers in sets of three. Hitting one is worth 10 points and causes the bumper to change color (green -> yellow -> red -> disappear). Destroying the third red bumper in each set of 3 is worth 500 points instead of 10.

Special stage: 100 points for each ring held (Sonic's rings as well as Tails', if applicable, both count in this total. An additional 10,000-point bonus is awarded by getting enough rings for the Emerald.
