Sonic the Hedgehog 2

-This story is set on West Side Island. According to legend, an ancient civilization here achieved prosperity using mysterious stones, whose misuse led to their downfall. These stones, believed to be the seven Chaos Emeralds, are said to have been sealed by the gods within the island's depths. During his travels, Sonic the Hedgehog discovers West Side Island and sets up camp there while unknowingly being followed by Doctor Eggman. He eventually meets a shy, two-tailed fox named Miles "Tails" Prower, who idolizes him and follows him around the island. -One day, Tails stumbles upon Sonic's plane, the Tornado, just as a massive explosion occurs in the forest nearby. As it turns out, Eggman settled on the island to find the Chaos Emeralds to power his ultimate weapon, a space fortress known as the Death Egg. Sonic immediately rushes to thwart his plans, with Tails following him. -Sonic and Tails journey through the island, freeing various Zones from Eggman's control and defeating the doctor on numerous occasions. They eventually use the Tornado to storm Eggman's flying Wing Fortress. However, it strikes the Tornado's wings, forcing Sonic board the battleship alone. Thanks to Tails' repaired Tornado, he boards Eggman's space rocket, leading him to the Death Egg. There, Sonic confronts and defeats a robotic doppelganger called Mecha Sonic before facing Eggman in his Death Egg Robot. After a heated battle, Sonic's victory triggers a chain-reaction that causes the entire Death Egg to explode. -The Death Egg's explosion causes a flash of pure white on Earth. Tails pilots the Tornado to search for Sonic, who barely escapes the space station, which falls into the atmosphere.

Emerald Hill Zone (エメラルドヒルゾーン, Emerarudo Hiru Zōn?) is the first Zone of Sonic the Hedgehog 2, its various ports and remasters, and the lock-on game Knuckles in Sonic 2. It is a tropical paradise on the shores of West Side Island. As with most other Zones in this game, Emerald Hill Zone consists of two standard Acts with a boss fight at the end of Act 2. ———————————————— Described as beautiful, Emerald Hill Zone is a tropical area with green meadows and rich waterfalls. The soil is orange-brown and has squareish patches and a checkered pattern on some points. Palm trees, shrubs, flowers and lime green grass fill the area, and there are waterfalls, loop-de-loops, corkscrews and caves with blinking green lights built into the walls. In the distance is a massive field filled with grass and yellow flowers, and it ends at the crystal blue ocean. The sky is navy blue with some clouds. ———————————————— During his hunt for the Chaos Emeralds, Dr. Eggman would invade all of West Side Island, including Emerald Hill Zone, which he kidnapped the local Animals from while filling said Zone with Badniks. ——————————————— Emerald Hill Zone soon after became the first Zone that Sonic and Tails would travel through to put a stop to Eggman's operations. On their journey through Emerald Hill Zone, they eventually investigate and locate the doctor in the Egg Drillster, which they have a battle against. After his vehicle is defeated, Eggman flees, while Sonic and Tails head to Chemical Plant Zone.

Three airborne Rings are visible at the start, followed by three more guarded by a Coconuts. Right of there is a floating platform with a Buzzer, leading to a ledge with a Shield monitor, along with another Coconuts guarding three Rings. Four more Rings are placed below the ledge on a slant. After that is a rope bridge with Mashers, and five more Rings above it. The hill meanders upwards and then downwards; next to the crest is another Coconuts. It then splits into two paths, with floating platforms between the first two gaps.

Taking the upper route, the island between the gaps has a yellow Spring and a Buzzer. The next floating island has four Rings followed by another yellow Spring which leads to the next floating island. The player can avoid the Spring and go for the Super Ring monitor and four Mashers instead, rising from the small gaps in the terrain. A Power Sneakers monitor is guarded by spikes to it left and a Coconuts from above. The land curves downwards and slants to a wall. At the top of this wall is a yellow Spring with leads to a floating island to its left, which has six Rings and a Star Post. To the right of the yellow Spring is a floating platform and an invincibility monitor on top of the loop-de-loop. The loop itself has five Rings placed on a downwards slope. Past this slope is a corkscrew, with nine Rings placed on it, followed by another slant which if the player has enough speed, can collect all seven Rings. Shortly following the slant is a Ring monitor, a gap with a Masher and a Coconuts. The level then forks into two pathways, with a Spring on the floating island above which if taken, the player can collect up to nine Rings.

The lower route, if the player jumps over the red Spring on the left they can collect six Rings on the hidden passageway. The Spring takes them through the tunnel, guarded by moving spikes, through a slant with some Rings. A Super Ring monitor can be found inside the bushes.

Two Buzzers will appear as the ground becomes hilly before meandering into a little slant. Past the ledge is another rope bridge protected by two Mashers. At the end is a Shield monitor followed by another tunnel with upside-down spikes. Past there is a yellow Spring and a long slant up the wall onto a rope bridge, ending the split.

From this point, there is a Coconuts followed by a Star Post inside the ledge. Above the ledge (which can only be accessed via the floating island with the yellow Spring) are three monitors (one Invincibility and two Ring) guarded by two Buzzers. A yellow Spring takes the player across two loop-de-loops before slanting upwards. There is a hidden passageway to the right of the downwards red Spring which leads to some Rings and a One-Up monitor. Two more yellow Springs take the player to the top part of the level. Otherwise, they can take the lower route past the diagonal Spring, which is a simple sprint across tunnels, waterfalls and ledges. Past the rope bridge are two groups of spikes, with two Rings floating high on top of each group. After another slant is another Super Ring monitor behind the bush, followed by two Buzzers, another slant, a rope bridge protected by two Mashers, a Coconuts, and a horizontal yellow Spring that zooms the player into a slant up the final wall. Ahead of that is the Goal Plate, completing the Act. ——————————————— If the player does take the diagonal Spring on the loop, they will take the last upper section. There is a vertical spring leading to four tightly packed Rings, followed by three moving platforms. At the end of the final platform is a Coconuts beside the loop, and two Buzzers below it. On top of this loop are twenty Rings - ten either side - along with a Star Post in the middle. Ahead of the loop is a double corkscrew, worth seventeen Rings, followed quickly by a reverse diagonal Spring, which the player can collect an extra nine Rings.

There is a ledge at the start with a diagonal Spring that leads to a cluster of twelve airborne Rings. The Spring can be used to bypass the Badniks below to the ledge above: two Mashers followed by two Coconuts with a group of spikes in between the palm trees. On the ledge is a Power Sneakers monitor followed by two Buzzers and a Coconuts, while beneath it is simply a rope bridge with two Mashers, the terrain eventually slanting upwards to the next section. The path splits into two again. ——————————————— The player can take the floating platform to the high route, which has a Coconuts and spikes guarding three Rings, followed by a Spring and a wall. Jump into the wall and they will find a hidden section totaling twelve Rings. After the rope bridge are two Buzzers, in which this path terminates. From the Spring, they can jump onto the vertical floating platform up to a small floating island to its right, which has a maximum of twenty-nine Rings and another Spring on its left. Enough leftwards momentum will lead to an even smaller floating island with a Star Post. Onwards are the tops of two loops on a downward slope with a floating platform in between. Another Star Post is placed on top of the second one guarded by a Buzzer. A diagonal Spring to its right will take the player up to the high route.

As such, there are a huge amount of halls to utilize the playable characters as living pinball. Sometimes, the player has to curl into balls and then enter the pinball tables in order to progress in the Zone. Casino Night Zone also features many alternate routes. While lower parts of the Zone have more narrow pathways, the upper parts have more linear pathways.

On journey through the Zone, they eventually locate the doctor in the Egg Bouncer, which they have a battle against. After his vehicle is defeated, Eggman flees, while Sonic and Tails head into the skies in the Tornado.

in the game, the Tornado is featured prominently in Sky Chase Zone. The Zone consists of only one act with no boss to fight and the player can move the playable character on the top wing of the Tornado, piloted by Tails (or Sonic if playing as Tails). When the player moves forward, the Tornado follows him, but the player is able to fall off the biplane if they are moving too fast. When the player progresses to Wing Fortress Zone, the Tornado gets shot down by lasers while pursuing Dr. Robotnik and his flying battleship.

After defeating the robot, Sonic chases down the scientist across the Death Egg, who flees to his new Death Egg Robot and confronts Sonic.

Once the mech is taken down, the Death Egg begins to explode, but Sonic manages to survive by hurling himself out of an airlock into space. Looking like the end for Sonic as he descends through the stratosphere of his world, Tails appears and catches Sonic on the Tornado, thus ending the game, but if the player has all seven Chaos Emeralds, Sonic instead safely flies beside the Tornado as Super Sonic.

Each Special Stage consists of three parts. In each, the player has to collect a minimum number of Rings before specified checkpoints. Failing to meet a requirement causes the Special Stage to end. Upon completing all three parts successfully, the player is rewarded with a Chaos Emerald. Note that Rings are cumulative, the player keeps rings collected in one part as they continue on to the next. In the single player mode, it is vital that Tails doesn't hit any bombs if he is accompanying Sonic as this will cause players to fail.
