Revision as of 20:01, 17 October 2004

The second outing of Sonic on the Megadrive and the first game to feature Miles "Tails" Prower. Released November 24, 1992, the game has longer levels, more levels, and a faster pace. 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 seven balls in the Dragon Ball series. Super Sonic is also like a Super Saijin 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.

However, unfortunately for some, Sonic 2 removed the bonus points available from jumping at the end level sign, which you could do in Sonic 1.

The Sonic 2 Beta, found by Simon Wai, is famous for its deleted levels.

Levels

Hidden Palace Zone (Unaccessible without hacking)

The infamous Hidden Palace Zone has been found on the Cartridge, but with graphical data removed. It can only be accessed through hex editing, cheating devices, or savestates.

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 destroyes 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: If no copies of the "Ring" object are present anywhere in the level, this is 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.
