Sonic the Hedgehog 2

Sonic the Hedgehog (ソニック・ザ・ヘッジホッグ Sonikku za hejjihoggu?) for the Sega Mega Drive is the first title in the Sonic the Hedgehog series, and the third appearance of Sonic the Hedgehog. The game's original programmer was former Sonic Team leader and series creator Yuji Naka, and the planner was Hirokazu Yasuhara. The gameplay was faster than any other game before it and amazed many people at launch. This was due to the Mega Drive's Motorola 68000 processor, whose basic speed and ability to handle 16-bit numbers gave it incredible speed compared to its predecessor, the Master System. Nevertheless, a separate 8-bit version, which focused more on exploration than speed, was later released for said system.

Story

Somewhere on South Island, Sonic the Hedgehog's animal friends are disappearing. When he discovers that the evil scientist Dr. Ivo Robotnik has been kidnapping them and converting them into robotic Badniks - all as part of a plot to collect a legendary treasure known the Chaos Emeralds - Sonic decides it's up to him to save them, and embarks on a quest to free his friends. As Sonic races through the zones, he marks them as his territory and frees the animals from their both their robotic shells and the egg-like prisons. After Dr. Robotnik is defeated for the sixth time at his hideout, he will flee and abandon his laboratory as Sonic returns to the place his journey began.

While completely optional during the game's progression, the Chaos Emeralds can be claimed by Sonic in the first five zones if he holds fifty Rings before completing the first two acts, taking him to the Special Stage (AKA "Secret Zone"). In the game's normal ending, Sonic will give the player a testing look before posing for the screen, and Robotnik will be shown after the credits juggling the undiscovered Chaos Emeralds with a "Try Again" message. If the player succeeds in collecting the six Emeralds before clearing the game, a more satisfactory result ensues - they will suddenly fly out of Sonic's grasp as they react in a circle and then teleport away as nature is rejuvenated on the island, astonishing Sonic. If this happens, Dr. Robotnik will be shown after the credits to instead be childishly jumping on the "End" sign.

Gameplay

Sonic1
Title screen of the game.

Sonic the Hedgehog plays very similarly to other platformers, in which the titular character must get to the end of the stage in the allotted time, while collecting items along the way. Essential to the gameplay are the golden rings the player collects along his/her way in each level, a feature which would become one of the defining characteristics of the series. These items are regularly placed around the level map and serve multiple functions. First, the player collects rings to protect Sonic. As long as they have at least one ring, the player will not lose a life when injured. Instead, when hit, up to 20 of the rings the player has collected will fly outward and scatter around the immediate area for some seconds, some of which can then be retrieved before they disappear. If the player runs into an enemy without a single ring, they will lose a life. If the player collects 100 rings they will gain an extra life, and will gain an additional life for every 100 rings after that, provided the rings are not lost.

The beginning
An example of gameplay in the first zone: Green Hill Zone.

If the player has at least 50 rings at the end of an act, a giant golden ring will float above the finishing sign which can be jumped through to enter one of the Special Stages (this excludes the final act of a stage, when Sonic will enter a boss fight). At the end of each act, the total number of rings the player has is multiplied by 100 and added to the player's score. During the score-tallying, the player can also jump through the air to find hidden emblems which can range from 100 to 10,000 points.

Also scattered throughout each level are video monitors which, when broken by the character, reward the player with one of a variety of bonuses. These include a Shield which will protect Sonic from a single hit, a 10-ring bonus, an extra life, temporary invincibility (accompanied with a temporary change in music), and "Power Sneakers", which give the player a temporary speed boost (and increase the tempo of the music for the duration). The item monitors have become another long-lasting feature in the series, though they have been changed to bubble-like containers that can float in later games.

Despite the various types of protection available, neither the shield, rings, nor invincibility will prevent the player losing a life if Sonic is crushed (by a trap or between a wall and a moving platform), drowned, runs out of time (each act has a ten-minute time limit), or falls into a bottomless pit.

Progression through the game is made easier for the player by lamp posts that act as checkpoints. When Sonic passes a lamp post, the spherical top spins around and its color changes from blue to red, and the next time a life is lost, gameplay will restart at that point rather than at the beginning of the act. In the Japanese version, if a checkpoint is activated and a life is lost as a result of running out of time, the time at the checkpoint will reset to 0:00.

Hazards the player experiences include a wide variety of "Badniks" - these appear as animals trapped inside mechanical bodies which are released the moment the player hits them. Each badnik takes one hit to destroy, but they vary greatly from Zone to Zone; some will walk in a set path, others will try blasting the player, and some cannot be avoided at all. The player must also avoid rows of sharp spikes, cliffs, and elaborate death traps. There is also the threat of drowning (in Labyrinth Zone and the third act of Scrap Brain Zone which contains water), as the player can only survive approximately 30 seconds underwater (locating air bubbles can extend this).

Sonic's abilities

Name Sprite Description
Walk Sonic walk Push left or right on the D-pad to initiate Sonic's movement in either direction. As you hold the button down, Sonic gains speed.
Run Sonic run Begin walking and hold down the button to make Sonic gain speed. After a few seconds, he'll break into a run.
Screech halt Sonic screech While running, quickly press and hold the opposite direction on the D-pad to make Sonic screech to a halt. He'll skid for a short distance, based on how fast he was moving.
Look up Sonic lookup While standing still, press up on the D-pad to make Sonic gaze to the sky. As you hold up, the camera pans upward, giving you a view of Sonic's overhead surroundings.
Crouch Sonic crouch While standing still, press down on the D-pad to make Sonic duck down. As you hold down, the camera pans downward, giving you a view of the stage beneath where Sonic stands.
Super Sonic Spin Attack Sonic spin Often called the Spin Attack or just the roll in later games, pressing down on the D-pad while moving will make Sonic curl into a rolling attack. He'll remain in this position until you jump or slow down. The speed of Sonic's movement while in spin mode is based on how fast you're moving when you launch it, and also on the terrain Sonic rolls along.
Super Sonic Spin Attack Sonic spin jump Renamed the Spin Jump in later games, pressing an action button at any time will make Sonic leap into the air with rolling attack. The height of the jump is proportional to how long you hold the button down.
Push Sonic push Certain blocks can be pushed by running up against them. Continue holding the D-pad against the offending cube to have Sonic push it along the ground. This sprite will be shown if you attempt this with an object that can't be pushed but won't harm you.

Zones

Sonic the Hedgehog has seven zones (plus the Special Stages). The first six zones contain three full-length acts, and the final one only consists of the final boss machine.

  1. Green Hill Zone
  2. Marble Zone
  3. Spring Yard Zone
  4. Labyrinth Zone
  5. Star Light Zone
  6. Scrap Brain Zone
  7. Final Zone

Special Stages

Main article: Special Stage (Sonic the Hedgehog)

If Sonic finishes the first or second act of any of the first five zones with at least 50 rings, a large, spinning ring will appear. If he jumps into it, he will warp into a "Special Stage" (called the "Secret Zone" in the manual), which conceals one of the six Chaos Emeralds. In these stages, Sonic, in ball form, falls through a series of rotating mazes.

If he can avoid the "GOAL" signs along parts of the stage's walls (presumably labeled "GOAL" to entice the player into a failed attempt at getting a Chaos Emerald), he will eventually find the Chaos Emerald encased in colored diamonds; touching the diamonds repeatedly will cause them to change color from blue, to green, to yellow, to pink and ultimately disappear, allowing access to the Emerald. The stage will end when Sonic either touches the Emerald or hits a "GOAL" sign. If 50 rings are collected before Sonic makes contact with a "GOAL" sign or gets the Chaos Emerald, then a 'Continue' will be awarded to the player, indicated by a brief, distinct change in melody. Super Sonic does not appear in Sonic the Hedgehog because the seventh Chaos Emerald was not yet introduced.

There are a total of ten opportunities to get Chaos Emeralds, meaning the player can fail a Special Stage up to four times if all six Emeralds are to be collected before the end of the game. Scrap Brain Zone will not have a large ring at the end of it, even when finishing with 50 rings, despite the acts ending before it. If the player fails a stage, that stage is skipped and is returned to after attempting the sixth and final Special Stage.

It is stated in the North American and European manuals that a 1 Up item can be found in Special Stages, but they are not seen anywhere unless placed in the game's secret Debug Mode. It is possible, however, to earn extra lives by collecting 100 rings in a single stage, indicated by the same sound used in the main zones.

Items and Power-ups

Name Sprite Description
Ring Sonic ring As long as Sonic has some of these, he won't lose a life if he takes damage. Sustain a hit and all your collected Rings will scatter, giving you a brief opportunity to grab a few back before they disappear. (Rings will not protect Sonic from getting crushed by a trap, falling below the level, drowning, or running out of time. All of these effects result in instant death.) A 1up is awarded for every 100 Rings collected and each ring is worth 100 points at the end-of-act score tally. In many later games, Sonic can collect 50 of these to transform into Super Sonic (if the player has all seven Chaos Emeralds).
Video Monitor Itembox In each stage, you'll find a number of these power-up bearing monitors. Pop them open with a spin to procure one of five power-ups:
  1. Super Ring - Worth 10 Rings
  2. Shield - Absorbs one hit
  3. Power Sneakers - Temporary speed increase
  4. One-Up - Gives Sonic an extra life
  5. Invincible - Temporary invincibility
Lamppost Startmarker These hold your place in a stage: should you lose a life, you'll start back at the last star post you crossed.
Bumper Bobbin Round bumpers found only in Spring Yard Zone and the Special Stages. Bounce off one for 10 points, up to 10 times for a total of 100 points. (They stop dispensing points after the tenth hit.)
Spring Spring Sonic 1 Leap onto the broad side to catapult Sonic into the air. The yellow ones send him flying a short distance and the more powerful red ones send him farther.
Spikes Spikes Don't touch the pointy side! They're usually found in sets of three, but that's not a steadfast rule. Sometimes they're just lying out in the open, and sometimes they pop in and out of the ground (or the ceiling or walls).
Switch Switch Jump on the button to cause a change in the nearby scenery, usually necessary to proceed.
Air Bubbles Bubbles Large, oxygen-filled bubbles periodically rise from these clusters: tag one to fill Sonic's lungs with air and prolong the time you can spend underwater. Sonic can only spend 30 seconds underwater without drowning, and grabbing a bubble resets the timer. (Labyrinth Zone and Scrap Brain Zone Act 3 only)
Bonus Points Bonuspoint As you approach the bonus plate at the end of an act, leap into the air to find invisible bonus points that are added to your score. They can be worth 100, 1000, or a sweet 10,000.
Bonus plate Bonusplate These signs can be found at the end of each first and second act. Cross them to end the stage.
Special Stage Ring Specialring These giant rings appear above bonus plates when you cross with at least 50 rings on hand. Jump in to warp to the Special Stage. (Once you've collected all 6 Chaos Emeralds, the Special Stage rings no longer appear.) If Sonic does not jump in before the bonus plate stops spinning, he will uncontrollably run off of the screen and the Special Stage is lost.
Capsule Capsule These are found at the end of each third act, after defeating the boss. Push the button on top to destroy the machine and free the helpless animals within.

Enemies

English name Japanese name Sprite Description
Moto Bug Motora
(モトラ)
Motora Beetle bots with one wheel and two claws, a blue head, a engine, and a red back that roll innocently along the ground. They appear in Green Hill Zone. They are designed after ladybugs.
Buzz Bomber Beeton
(ビートン)
Beeton Blue bee bots that actually look like wasps with two yellow antennae with an engine that flies across from the right side of the screen, pausing once to fire a large flashing projectile from their stingers diagonally downward at Sonic. They are seen in Green Hill Zone.
Chopper Bata-bata
(バタバタ)
Batabata Red piranha bots that leap upward from beneath bridges, trying to chomp Sonic. It's best to walk on bridges while in a ball form. They appear in Green Hill Zone.
Crabmeat Ganigani
(ガニガニ)
Ganigani Red crab bots with 6 grey legs that crawl along the ground and fire projectiles from their pincers and shoot 3 inches in the air and then the projectiles drop to the ground.
Newtron Meleon
(メレオン)
Meleonb Meleong These chameleon bots hang out on the side of cliffs and remain invisible until approached. They come in two colors: blue ones transform into missiles and jet along the ground. Green ones appear just long enough to fire an energy blast at Sonic.
Caterkiller Nal
(ナール Nāru)
Nal Purple Caterpillar bots with yellow spikes on their body and two yellow antennae that crawl slowly along the ground. The safest method of disposal is to roll into their spherical heads: venture a poke anywhere else and you'll sustain damage and send their segments flying. Caterkillers appear in Marble Zone and Scrap Brain Zone.
Bat Brain Basaran
(バサラン)
Basaran Blue bat bots with one engine, two black or grey claws, and black wings that latch onto ceilings until approached, then drop down and fly through the air a short distance before returning to their roost.
Roller Arma
(アルマ)
Arma Blue armadillo bots with a red face that roll down long slopes after Sonic. They tumble faster than Sonic runs, so leap to avoid being steamrolled. At the bottom of the hill, Roller pauses and briefly opens up: this is your only chance to attack.
Spikes Yadorin
(ヤドリン)
Yadorin Purple hermit crab bots with two purple and yellow claws and two yellow wheels that crawl along the ground. Their shells are cloaked with spikes, making them invulnerable from above.
Burrobot Mogurin
(モグリン)
Mogurin Mole bots with two tractor-like wheels, a blue head, and red shoulders, helmets, and arms that spring from underground and roll along the surface. Look for their drill bit noses poking out of the earth to avoid an ambush.
Jaws Puku-puku
(プクプク)
Pukupuku Purple piranha bots with a yellow jaw and yellow eyes that swim around underwater. ("Puku-puku" is Japanese onomatopoeia for a bubbling noise.)
Orbinaut Unidus
(ウニダス)
Unidus Irritable blue sphere bots that hover around very slowly. They're orbited by four red spiked balls which they fling off in rapid succession upon being approached. It's a dangerous assault, but once it's done, Unidus is completely open to attack. ("Uni" is Japanese for sea urchin.)
Uni Uni
(ウニウニ)
Uniuni These guys, palette aside, look exactly like Unidus. They're a bit more cool-headed, though, with a green sphere in the middle and four yellow spikes surrounding it and won't fire off their barrier of orbs. While this means you don't have that tricky attack to avoid, they're virtually impossible to hit.
Bomb Bomu
(ボム)
Bomb Mindless bots with gray top and red bottom with two gray legs. Even though they never move, they explode in 5-6 seconds after making contact with it into a shower of projectiles when approached. They can't be damaged, only avoided.
Ball Hog Tonton
(トントン)
Tonton Pink Pig bots with a gray ears, gray stomach, gray legs, and a turquoise nose that hop in place atop steep banks and roll balls down the slope. They only appear in Scrap Brain Zone.
Splats Spratt
(スプラット)
Splats Blue rabbit robots that just bounce around. These badniks weren't used in the original release, but appeared in pre-release copies of the game and made appearances in promotional art. In the 2013 mobile re-release, they are enabled as valid objects in the game's Debug Mode.

Bosses

Robotnik 50
Dr. Robotnik

At the end of the third act of each zone (except the Scrap Brain Zone), Sonic faces off against Dr. Robotnik, who is piloting his mobile. For each battle, Robotnik's machine has a different tactic. Sonic must hit each boss 8 times to destroy it.

  1. Eggmobile-H (Green Hill Zone)
  2. fireball weapon (Marble Zone)
  3. spike drill (Spring Yard Zone)
  4. trapped retreat (Labyrinth Zone)
  5. mine dropper (Star Light Zone)
  6. Final Zone

Master System and Game Gear

As the Master System still had high sales in South America (and in limited amounts in the US through retail stores), an 8-bit incarnation of Sonic the Hedgehog was produced for the Master System market. This version had similar zone themes and regular enemies, but entirely different level layouts and bosses. The Master System version was released for the Wii Virtual Console on 4 August 2008. This version was also made available worldwide for the Game Gear, with adjustments due to the smaller screen.

Manuals

English

The English story prologue found in the North American and European manuals:

Crush Dr. Robotnik!

Dr. Ivo Robotnik, the mad scientist,
is snatching innocent animals and
turning them into evil robots! Only
one tough dude can put an end to
the demented scientist's fiendish
scheme. It's Sonic, the real cool
hedgehog with the spiked haircut
and power sneakers that give him
super speed.

Help Sonic fight hordes of metal
maniacs and do the loop with the
Super Sonic Spin Attack. Speed
down twisting tunnels and swing
over dangerous booby traps. Leap
across lava pits and dodge burning
rocks. Then splash through the
chilling waters in an underground
cavern.

And if you're lucky, you can warp to
the secret zone where you can spin
around in a floating maze! Your
greatest challenge lurks in a secret
lab where you come face to face
with Dr. Robotnik himself!

Spin through space, loop 'til you're
dizzy, save the animals and become
the super hero. Be Sonic! Be
atomic!

Japanese

A translation of the story prologue from the Japanese manual:[2]

The evil mad scientist Dr. Eggman is up to his old nasty tricks again.
"Sonic…that annoying, impertinent hedgehog. Thanks to him, my great plans are always laid to waste! Oh, but this time, I'm going to rub him out with the power of science! Ha ha ha ha ha…"

South Island is a treasure trove of gems and ancient ruins. They say that it's the island where the mystical Chaos Emeralds lie. The Chaos Emeralds are a super-material that give energy to all living beings. Also, when applied to scientific purposes, they can be used for nuclear and laser based weaponry. However, nobody knows exactly how to get ahold of these emeralds. At the same time, though, they do say that the reason why South Island is always moving is because the emeralds are somewhere inside the island's hazy depths.

One day, crisis visited upon the island. And who showed up with it but Dr. Eggman and his cronies.
"I'll find those emeralds even if I have to dig up the entire island to do it!"

Dr. Eggman set up a fort in one corner of the island, and went about carrying out his plan.

"Eggman, you still haven't had enough?"
Sonic hurried as soon as he heard the news. Dr. Eggman never seemed to leave him alone, even though Sonic had beaten him every time so far. It sounded like Dr. Eggman considered Sonic his sworn enemy, but he was never any match for Sonic.

However, this time something is amiss.

"Have you seen it, Sonic? This time is going to be different! Because this time, I've turned all the animals on the island into robots!"

"E...Everybody!?"

"All of them go about in accordance to my orders. In other words, Sonic, everyone on the island is your enemy! Gya— Ha ha ha ha ha ha ^cough^ ^ack^ ^ahem^. This time, the world really will be all mine!"

This is terrible! Hurry! Sonic the Hedgehog - everyone is waiting for your help!

Cheat codes

  • Level select - At the title screen, press UP, DOWN, LEFT, RIGHT, then hold A and press start.
  • Debug mode - At the title screen, press UP, C, DOWN, C, LEFT, C, RIGHT, C (or C, C, UP, DOWN, LEFT, RIGHT), start, then hold A until the game starts.

Note: These codes do not work on the Xbox Live Arcade and PlayStation Network versions of the game. They also do not work in the game unlockable in the Xbox 360 version of Sonic Generations.

iOS and Android version cheat codes

Note: This is for version 2.0 of Sonic the Hedgehog on iOS and the v1.0 of Sonic the Hedgehog for Android Devices. If you have v1.0 on your iOS device, update it through the App Store (the update is free for those who own this, however, all saved data made prior to 2.0  will be lost as it's a new port and it's incompatible). Android users don't have to worry about this as this is a new game to Android users. You must choose No Save Mode to activate these:

  • Level select- At the opening Sega logo, touch the letters S, E, G, A in that order. (This doesn't work with the first SEGA logo shown or save files.) When the title screen appears, press the screen with two fingers at once. You will be taken to a new level select screen, very similar to the one from Sonic the Hedgehog 2. New is that one can change their character, spindash options, speed cap options, and spikes options (activating the old lack of invurnability for spikes or not).
  • All Chaos Emeralds- Go to your level select screen and play songs in this order 04, 01, 02, and 06 from the Sound Test.
  • Super Sonic- Perform the level select code then the All Chaos Emeralds code. On the level select change the Max Emeralds setting from 6 to 7. Then you can use Super Sonic after collecting 50 Rings in any stage. You should replay the All Chaos Emeralds code first. This can be used for Super Tails and Super Knuckles. Note: Super Tails won't have Flickies.
  • Debug mode- From the level select, play sounds 01, 09, 09, 01, 00, 06, 02, and 03 in that order from the Sound Test. After starting a level, tap the GUI in the top-left corner of the screen to activate/deactivate debug mode.
  • Character Select- From the level select, change the player option from 0-3. 0 is Sonic and Tails, 1 is Sonic, 2 is Tails, and 3 is Knuckles.

Change Tails' name to Miles the same way you would tap the S E G A , for the level select, you press A G E S so type the level select cheat backwards.

Glitches

There are six particular glitches in the game that could either help or make things much worse for Sonic.

  1. Too fast Sonic in the Green Hill Zone; Result: If going too fast down two tubes in Green Hill, the camera won't respond and Sonic will die at the ledge to the giant ring pattern.
  2. Rolling after Labyrinth Zone Act 2's end; Result: An illegal instruction error will proceed if this glitch is triggered, making the player reset the game.
  3. Too many hits on the Final Zone's boss; Result: If timed correctly, the player can hit Robotnik two times on the final hit, showing that he would need to be hit 255 more times.
  4. Sonic jumps too far away in the Final Zone; Result: Sonic would jump off into the bottomless pit, therefore losing a life.
  5. Move through walls in Scrap Brain Zone; Result: On one of the moving platforms, Sonic can duck and go through the wall, showing that he has been placed in another location.
  6. "Spike Bug"; Result: Though this is technically intentional, Sonic isn't invulnerable to spike damage immediately after taking a hit. This causes instant death (or an endless loop, if on debug mode). This was changed in later games and in certain ports.

This version keeps track of time (similar to the Sonic Jam release). In addition, a new bonus feature can be unlocked via the Skill Shop - infinite continues. The Xbox 360 version lacks the level select code, but the PlayStation 3 version has it intact. It is removed from the PC version in favor of slightly enriching the core game experience.

At the Game Developers Conference 2013, a remastered re-release of the original Sonic the Hedgehog was announced for iOS and Android. It was developed by indie developer Christian Whitehead and Headcannon using Whitehead's "Retro Engine" that was previously used for the 2011 re-release of Sonic CD. The release runs at 60 FPS, includes a time attack mode, and has widescreen support and a remastered soundtrack. The game costs $2.99 and was released on 16 May 2013 (it was released as an update to iOS users).

Like in several previous emulation ports, Spin Dash is an optional move in the port. There are several graphical changes compared to the original game. Despite not being officially introduced yet in the series, Miles "Tails" Prower and Knuckles the Echidna in their Sonic the Hedgehog 3 & Knuckles styles are unlockable characters, with mild tweaks to the level design to accommodate their gameplay. It also features a mode in which Tails follows Sonic and can even carry him while flying. In addition, the hidden level select and Debug Mode options are greatly expanded, taking elements from the sequels as well as incorporating recreations of unused content.[6]

Trivia

  • The Japanese release added additional storyline details, as the existing plot was virtually a basic outline. The purpose of the Chaos Emeralds is greatly expanded upon, which is elaborated in later games. It is explained that Dr. Robotnik was specifically searching for them on the island due to their incredible energy according to legend. The manual also states that there has already been some unknown animosity between Sonic and Robotnik in the past (which, on the other hand, is not backed up in later games). It also lists the setting as South Island, which is established in later games as well - in the English manual, the setting was originally unnamed.
  • There are two versions of the game. This revision is common in Japan, but contrary to popular belief it was released worldwide in smaller quantities. This update makes some very minor changes to the game's programming, as well as adds some visual effects such as scrolling clouds in Green Hill Zone or water ripples in Labyrinth Zone. It also corrects the zone order on the level select. This version of the game is used is most subsequent releases. In addition, the scrolling clouds return in most appearances of Green Hill Zone.
