Gameplay

Production

Sonic 2 differed from the original Sonic the Hedgehog in that it was produced at the Sega Technical Institute in the United States, and experienced Japanese Sega members such as Yuji Naka and Hirokazu Yasuhara (the first game's lead programmer and game planner respectively) were brought in to work alongside the American developers. Two artists in particular stand out: Brenda Ross and Craig Stitt. Peter Morawiec and Tim Skelly also worked on some art for the Special Stages. Yuji Naka Yuji Naka (中 裕司 Naka Yūji, born September 17, 1965), is a video game designer and head of Sonic Team, a group of Sega programmers/designers. ... Hirokazu Yasuhara is the stage designer of several of the early Sonic the Hedgehog videogames. ...


Ashura the Hedgehog

One of the more famous "codes that were never meant to be," the sometimes named "Ashura in Sonic the Hedgehog 2 code" is often attributed to Charles "Kiken" Mugg. Due to a palette glitch in debug mode that can only be done in Emerald Hill Zone, Sonic can sometimes take on green and black hues replacing his famous blue shade. Charles went on to create a fan character named "Ashura" (the Japanese word for Asura, which does not actually mean demon) based on this glitch, back when the concept was still fairly original. The Ashura name spread like wildfire, causing some to think that Ashura was actually an official Sega character. But as time passed, most had realized it was merely a fan creation and nothing more. It is only mentioned here because of the character's importance in the evolution of the fan community and its roots in Sonic the Hedgehog 2. In Hinduism In Hindu mythology, the Asura are a group of power-seeking deities, sometimes misleadingly referred to as demons. ...


In conclusion: Ashura has never been, and never will be an official character.


List of zones

Below is a list of zones in Sonic the Hedgehog 2, in order of appearance in the game. Each describes the boss section of the zone, in which Robotnik attempts to defeat Sonic.


Emerald Hill Zone

A green island with big fields and beaches and other tropical islands in the distance. The boss in this zone has Dr. Robotnik in a drill-equipped dune buggy. After seven hits, Robotinik shoots the drill bit at Sonic; one more hit destroys his machine.


Chemical Plant Zone

Dr. Robotnik's chemical plant, full of tubes and floating platforms. He uses a new substance called "Mega-mack" to try to kill Sonic by vacuuming up this substance and dropping it on Sonic. As long as Sonic is ducking he cannot be hurt by this. This level is also notable for a brief rising-water section, which provides a rather steep learning curve for new players.


Aquatic Ruin Zone

An ancient ruin located in a forest valley partially submerged in water. Dr. Robotnik tries to use the ruin's technology against Sonic between pillars that spit out arrows.


Casino Night Zone

A city that never sleeps, full of pinball rooms, flashing lights, and slot machines. Dr. Robotnik tries to kill Sonic with his neon spike-ball machine.


The slot machines give out different prizes depending on when the reels land:

  • 3 Rings: 10 rings
  • 3 Bars: 20 rings
  • 3 Tails: 25 rings
  • 3 Sonics: 30 rings
  • 3 Jackpots: 150 rings
  • 3 Dr. Robotniks: lose 100 rings (be careful!)

In addition, a Jackpot or two can also act as a wild card or wild cards, rewarding rings even though the other reel(s) are not Jackpots. Sometimes they merely fill in for the missing icon, other times they act as doublers:

  • 2 Tails, 1 Jackpot: 50 rings
  • 2 Sonics, 1 Jackpot: 60 rings
  • 2 Jackpots, 1 Tails: 100 rings
  • 2 Jackpots, 1 Sonic: 120 rings
  • Jackpots and Dr. Robotniks: lose all rings (be very careful!)

A Bar will also give out rings depending on how many there are:

  • 1 Bar: 2 rings
  • 2 Bars: 4 rings
  • 3 Bars: 20 rings (see above)

Note: In this case, Jackpots only act as doublers in the case of only Jackpots and Bars, i.e., two Bars with one Jackpot is worth 40 rings, and one Bar with two Jackpots is worth 80 rings, but one Bar and one Jackpot is only worth 2 rings.


Hill Top Zone

A zone on a mountain high above the clouds. The mountain is also an active volcano. Dr. Robotnik uses the volcano's lava to shoot fireballs and set the grass alight in his Lava Submarine. Depending on one's route through the level, Sonic may face an earth- or lava-quake in the Second Act.


Mystic Cave Zone

An old, dark abandoned mine inhabited by Badniks that attempt to shock or collide into Sonic. Dr. Robotnik tries to stab Sonic with sharp debris as he uses his machines to drill into the ceiling of the mine. A Badnik is a term for an enemy robot in the early North American and European versions of the Sonic the Hedgehog video games. ...


Oil Ocean Zone

A zone polluted by Dr. Robotnik's oil-drilling projects. The viscosity of the oil allows Sonic to run across it, although he can still die in the oil if he is totally submerged in it. The Badnik "Aquis" is found in this zone. It is a fast moving and dangerous mechanical seahorse, and is able to float around in the air, never touching the ground. Dr. Robotnik tries to kill Sonic in his submarine again but uses spikes and lasers this time. But the whole time, he is messing around with your mom behind your back.


Metropolis Zone

An extra-long level, in which Dr. Robotnik resides. There are lots of machines, including the Pipe Teleporter and screw elevators, as well as Badnik stars which explode to puncture Sonic. Dr. Robotnik protects himself against Sonic with spiraling eggs each containing a fake Robotnik.


Metropolis Zone had 3 acts, like Sonic 1. However, all the other zones in Sonic 2 had two or one. This was because Tom Payne (the artist in charge of this level) had also been assigned another level that was finally scrapped due to lack of time, leaving him to work on this third act.


Sky Chase Zone

In order to chase Dr. Robotnik, Tails uses his Tornado plane to fly into the sky to battle Concorde birds and turtle battleships. This is a very short level with one act and no bosses.


Wing Fortress Zone

After Tails's plane is shot down, Sonic jumps onto Dr. Robotnik's sky ship, where he has to avoid falling to his doom and reach the bridge to Dr. Robotnik. Sonic is ambushed and has to dodge a massive laser whilst spiked platforms rotate around the room. You must jump onto these platforms to hit the laser which moves left to right, embedded in the roof. If you touch the bottom of the platform you lose all rings/die as they are spiked at the bottom. After 8 hits you blow the ship's circuits and Dr. Robotnik tries to escape in his spaceship. Tails comes back with the tornado (biplane) and flies Sonic close to the ship using a rocket booster installed at the bottom of the plane. Sonic grabs on to Dr. Robotnik's ship and gets to the Death Egg.


Death Egg Zone

Sonic must battle against a silver Sonic robot with no rings to help him. After defeating the robot, Sonic chases Robotnik into a giant armoured battle suit, the last boss that Sonic has to destroy. After defeating him, he runs out of the exploding Death Egg and skydives back down, and is caught by Tails's plane (unless one has managed to collect all the Chaos Emeralds; in that case Super Sonic flies alongside the plane). A Chaos Emerald is a mystic item that appears in the Sonic the Hedgehog video games, allowing the holder of all seven of them to transform into a super form. ...


Secrets

Knuckles the Echidna in Sonic the Hedgehog 2 is a game activated by locking Sonic the Hedgehog 2 to the passthru cartridge of Sonic & Knuckles that was released later by Sega. The resulting game is almost identical to Sonic the Hedgehog 2, except that one plays as Knuckles the Echidna. Although some fans believe that Sonic 2 was created with foreknowledge that such an add-on device would be made later, this is incorrect. The majority of the changes to Sonic 2 are actually contained in the Sonic & Knuckles cartridge and loaded at boot if a Sonic 2 cartridge is found in the pass-through slot; the actual Sonic 2 data is accessed very rarely. Sonic & Knuckles title screen Sonic & Knuckles is a platform game in the Sonic the Hedgehog series, released for the Sega Mega Drive/Genesis in 1994. ... Knuckles the Echidna Knuckles the Echidna is a character in the Sonic the Hedgehog series of video games, television shows and comics. ...


Time restrictions necessitated dropping some features and levels from the final game. Remnants of these like incomplete levels and unused sounds and graphics have been revealed through study of the internals of the game using emulators along with a debug mode. In computer and video games, a level (sometimes called a stage, course, map or landscape) is a separate area in a games virtual world, in modern games typically representing a specific location such as a building or a city. ... Debugging is a methodical process of finding and reducing the number of bugs, or defects, in a computer program or a piece of electronic hardware thus making it behave as expected. ...


The game's level select code, activated by playing music within the game, is 19, 65, 09, 17; Sonic programmer Yuji Naka's birthday is September 17, 1965. Its debug code is 1, 9, 9, 2, 1, 1, 2, 4; Sonic 2's U.S. release date was November 24, 1992. Yuji Naka Yuji Naka (中 裕司 Naka Yūji, born September 17, 1965), is a video game designer and head of Sonic Team, a group of Sega programmers/designers. ... September 17 is the 260th day of the year (261st in leap years). ... 1965 was a common year starting on Friday (link goes to calendar). ... November 24 is the 328th day (329th on leap years) of the year in the Gregorian Calendar. ... 1992 is a leap year starting on Wednesday of the Gregorian calendar. ...


Beta version

On the Internet, a widely distributed prototype of the game, better known as Sonic the Hedgehog 2 beta, has been discovered by Simon Wai, which features several incomplete zones. Only four levels can be played in "normal" gameplay; the rest have to be accessed through the level select code. Many are not playable, so the debug code is used to explore the acts. Some of the acts are empty, causing Sonic and Tails to fall to their doom immediately after beginning the level. The beta is frequently examined by hackers to determine how Sonic the Hedgehog 2 was developed. Prototypes or prototypical instances combine the most representative attributes of a category. ... In software engineering, development stage terminology expresses how far through the development sequence things have progressed and how much further development a product may require. ... Hacker is a term used to describe people proficient in computers, who employ a tactical, rather than strategic, approach to computer programming, administration, or security, as well as their culture (hacker culture). ...


In Asia and Brazil, the beta version was put on cartridges and passed off as the final version by pirates who are believed to have altered it slightly to stop the Sega logo from showing when the game boots up, as was common practice. World map showing location of Asia Asia is the central and eastern part of Eurasia, defined by subtracting Europe from Eurasia. ... The copyright infringement of software is often called software piracy by those seeking to reduce its incidence. ...


A mock-up picture exists which suggests that at one stage in development, a desert-like zone was planned in a Sonic 2 prototype, which until recently was believed to be named Dust Hill Zone. However, there is nothing to suggest that the level has ever existed in a playable format. The only official name that is known for this zone is "Sabaku", or "Desert", zone.


In addition to the renamed zones, such as Green Hill Zone which became the Emerald Hill Zone, Dust Hill Zone which became the Mystic Cave Zone, Neo Green Hill Zone which became Aquatic Ruin Zone, and Sky Fortress Zone which became Wing Fortress Zone, the following levels exist in the beta version of the game.


Wood Zone

A dense forest zone with only the very beginning of Act 1 programmed, and that itself is very glitchy. The music is the same as that in the Metropolis Zone. There are no enemies present in the Wood Zone. Without the debug mode activated, this level is cut very short due to the fact that it is impossible get past the first ramp, the characters hit the floor above instead. However, using debug, it can be further explored. The stage suddenly ends halfway through an animated (though not active) conveyor belt. Act 2 has no data. Glitch City, a Pokémon programming error that creates a jumble of pixels. ...


Genocide City Zone

This level's data has either been removed, or not yet coded, and the player falls and dies immediately upon entering the level. The music used is that of Chemical Plant Zone.


Hidden Palace Zone

The Hidden Palace Zone appears to be an underwater cavern with large crystals in it. The music used is that of the 2-player mode of Mystic Cave Zone. It contains badniks never seen in the released version, such as a red dinosaur badnik. The large emerald found in this stage has at times been suggested to be the Master Emerald, however those who worked on the zone have said it was just another block to break through. At one point in the zone is a long shaft which appears as if it was intended to loop from the top to the bottom of the map, but even if one navigates to the other end, there is not much left to the stage besides an animated (but as in the Wood Zone conveyor belts, not working) water slide. Act 2 is identical to Act 1, except the player is stuck inside a wall at the start, and all objects and enemies are gone. The Hidden Palace Zone refers to two levels in Sonic games, one being an unfinished level in Sonic the Hedgehog 2, the other being a level in Sonic & Knuckles. ...


Some suggest that music 10 in the final Sound Test, which was unused, was intended for this level. In addition, while the art was removed from the final game, the collision data remains, and the level itself can be accessed by entering the Game Genie code ACLA-ATD4 and using the Level Select to go to Death Egg Zone. This has led some researchers to believe that Hidden Palace Zone was intended to be in the final game as a "hidden" level that could be accessed only through a cheat code.


Death Egg Zone

According to the level select, this zone originally had 2 acts (unlike in the final version). But like Genocide City, neither act has any data and the player merely falls and dies immediately. No music is played in this zone.
