Sonic Rush

Sonic Rush is the name of a game for the Nintendo DS. Sonic Rush capitalizes on the 'dual screen' aspect in three ways; one, it uses the two screens like one extended vertical screen, for very steep climbs and drops; two, the game centers on two parallel universes colliding; three, the game features two hero characters, Sonic the Hedgehog and Blaze the Cat. The Sequel of the game is Sonic Rush Adventure.

The game is combination of 2D (for standard fights) and 3D (for boss battles). The stylus of the DS is largely unused, except in map mode and for special stages.

Story
The game's story centers around two characters in two alternate universes, Sonic and Blaze, as they both try to save their world with the use of the Chaos Emeralds and Sol Emeralds. However, the more they obtain, the more their actions have a 'ripple effect' on the other world. In gameplay, this means that what Blaze does in her game will affect what Sonic can do in his, and vice versa.

Gameplay
Sonic Rush is a 2D platform game, similar to earlier games in the series as well as later ones like Sonic Advance. In the tradition of past Sonic games, the player (playing as either Sonic the Hedgehog or Blaze the Cat) moves quickly through levels, collecting rings and defeating enemies The player collects rings as a form of health; when they are attacked by an enemy, their rings bounce in all directions. If they are hit by an enemy and have no rings, they lose a life. Both of the DS's screens are used to display the play area, with the player's character moving between them as necessary. Levels in the game are divided into "zones", each consisting of two acts of normal gameplay then a Boss battle. Although the game is primarily two-dimensional, there are three-dimensional elements which create a 2.5D effect. For the first time in the series, Sonic and Blaze's sprites are rendered in 3D Boss battles—in which Blaze fights Doctor Eggman and Sonic fights an Eggman doppelgänger called Eggman Nega are also rendered in 3D. The special stage features Sonic running through a wide and very long three-dimensional half-pipe, collecting rings to meet requirements, with a goal of collecting Chaos Emeralds—colored jewels that are a central theme to the series. It is similar to the special stage of Sonic the Hedgehog 2.

New features include a grading system that grades the player based on the time it takes for them to complete the level; they can return to levels later to try for a higher grade. There is a point system based on the one in Sonic Advance 2 but displaying points in multiple categories. There is also a "Tension Gauge" on the left side of the screen which is filled by doing tricks and defeating enemies. The energy it generates allows the player to use boosts of speed while moving; defeating enemies, moving through the level more quickly which results in more points and a higher grade, and when playing as Sonic, accessing the special stage.

Sonic Rush has a Multiplayer mode in which Sonic and Blaze race to the end of a chosen level from the game. There is also a feature in which players who own the game can send a demo of the game to other Nintendo DS users.

Plot
Blaze the Cat lands somehow in Sonic's world from her own dimension (unofficially dubbed the "Sol Dimension" by fans). She has seven Sol Emeralds—similar to the Chaos Emeralds—but they are stolen by Doctor Eggman. She then makes it her goal to retrieve them; this is where Sonic meets her (the Chaos Emeralds were stolen from him by Eggman Nega.) While she is searching for the Sol Emeralds, Sonic is searching for the Chaos Emeralds. Blaze meets Cream the Rabbit, and is surprised by Cream's politeness. Meanwhile, Tails learns that Blaze's world and Sonic's are beginning to merge somehow. Sonic begins to grow suspicious of Blaze and, along with Tails, looks for her. Soon, Sonic and Tails find Blaze and Cream. Sonic questions Blaze about her nature, but she refuses to give any information and leaves with Cream. Sonic follows her, and when he meets her on Eggman Nega's base, it is revealed that Eggman and Eggman Nega are working together to collect both the Chaos Emeralds and the Sol Emeralds. She declares that she will destroy Eggman Nega. When Sonic once again questions her nature, she turns on him and fights him. During the fight, Blaze tells Sonic that she is the only one who can save their worlds, so he should help her. However, Sonic wins the fight, and Blaze realizes the error of her ways. Eggman kidnaps Cream, and Blaze goes after him while Sonic takes on Nega. Sonic collects the last of the seven Chaos Emeralds; and meets Blaze, who has failed to rescue Cream and to restore the two worlds. Sonic and his friends help Blaze realize the meaning of friendship, and she turns into Burning Blaze—apparently her answer to Sonic's Super Sonic form—while Sonic turns into Super Sonic. They fight Eggman and Eggman Nega and defeat them. The two worlds are restored, Sonic and Blaze chat for a minute about how they'll miss one another especially Cream who'll miss Blaze. Blaze tells Sonic it's for the best. She leaves like this. She thanks Sonic for his help and friendship, etc. But before she goes off Sonic stops her and says they'll meet again and she replies "yes...again" she slowly goes over to Sonic as Sonic slowly goes up to her (both still in super form), they stare at each other for a while and holds hands as their dimmensions pull them back to their rightful worlds forcing Blaze into her own world Sonic as well. As she flies there, she realizes that she truly understands her powers. Later, on Sonic's planet, Cream is crying because she misses Blaze, but Sonic tells her that Blaze promised to return someday. (Sonic meets Blaze again in Sonic Rush Adventure, but Cream does not.)

Development
Before Sonic Rush was released, a short demo, Sonic E3 Demo, was developed. The gameplay involved rubbing the DS's touch screen to make Sonic run along a predetermined path and trying to complete a simple race course. The demo was rendered in 3D, but only one level could be played. After the demo was finished, Sonic Team began work on Sonic Rush. Developer Akinori Nishiyama said in an interview that Sonic Team wanted to make Sonic Rush two-dimensional, as the Sonic Advance trilogy had been, but add some three-dimensional elements. Nishiyama said that "for [the] Sonic DS title, we wanted to keep the elements from 2D, yet still explore some of the new elements from 3D. So we wanted to try to find a way to somehow marry both elements from 2D and 3D. After the release of Sonic Rush, a sequel, Sonic Rush Adventure, was developed and released on September 18, 2007.

Music
The music of Sonic Rush was written by acclaimed Sega composer Hideki Naganuma. It was released in Japan as a CD, SONIC RUSH Original Groove Rush, on November 23, 2005 through Wavemaster Studios. The CD has 45 tracks, seven of which are digital remixes rather than master tracks.

Reception
Sonic Rush was released on November 15 2005. It has sold 2.87 million copies worldwide, including 1.08 million in the United States. The game received mostly positive reviews from critics upon its release. It has a Game Rankings score of 83% and a Metacritic score of 82%.

The game was praised for its similarity to older games in the series as opposed to more recent ones. GameSpy staff writer Greg Sewart gave the game a 3.5 out of 5, praising the gameplay for being "a throwback to yesteryear" with "gorgeous graphics". GameSpot's Jeff Gerstmann gave the game 8.2 out of 10, calling it "a great Sonic the Hedgehog game that modernizes the old 2D formula a bit, though without losing what made those games so cool in the first place." IGN staff writer Craig Harris gave the game a 9.0 out of 10, claiming that it "does a great job offering a fantastic, energetic old-school challenge that keeps the classic gaming style alive." Nintendo Power staff writer Steve Thomason called the game "a back-to-basics, blazingly fast performer that hearkens back to the hedgehog's 16-bit glory days on the Sega Genesis."

The game's music was well-received. GameSpot's Jeff Gerstmann claimed that "[t]he high-tempo, sample-filled electronic tracks have a Jet Grind Radio-like sound to them, and they fit the action really well." GameSpy's Greg Sewart called the music "all very fitting and very catchy, filled with voice samples and a really quirky style." 1UP.com's review called it "bright and buoyant".

The game was criticized for its overall quickness. GameSpy's Greg Sewart, although giving a mostly positive review, complained that "rapidly in this game is so fast you almost can't tell what's going on most of the time. 1UP.com, though giving the game a B+, noted that "it's easy enough to blast through a level in no time at all and the speed encourages that. GamePro's staff writer "Ouroboros" said it was "bad news if you're tired of racing through yet another water or jungle environment.

On October 24, 2008, the game was listed at #17 in IGN's list of the top 25 Nintendo DS games.
