Sonic Adventure (Japanese: ソニックアドベンチャー, Sonikku Adobenchā) is a 1998 Action Platform video game by SEGA, for the Dreamcast, being the first Sonic game released on the system. It was later re-released on GameCube and Microsoft Windows as Sonic Adventure DX: Director's Cut, which included bonus content and updated graphics. Development was supported by NOW Production. A high-definition update[1] was also released in 2010 on Xbox Live Arcade and the PlayStation Store.

Plot[edit | edit source]

Each character has their own story, however, they collide at numerous points. Sonic's story starts off with him in a blocked off portion of the city, fighting a creature known as "Chaos". After beating it, a cutscene plays, which shows Sonic enjoying the beach, relaxing on a sunbathing chair. He notices Tails flying above, however, his plane begins to sputter and ultimately crashes somewhere along the coast. Sonic finds him, and the duo head back to the pool area. Tails laughs it off, saying he was trying out a new fuel source: the chaos emerald. He then invites Sonic over to his workshop where he is approached by Dr. Eggman and fights his machine: The EGG HORNET. After defeating Dr. Eggman, a stone appears in front of Tail's workshop, which is the key to unlock the level Windy Valley.

Trivia[edit | edit source]

  • The game is notable for being very glitchy, allowing speedrunners to finish the game in just 40 minutes.
  • There's a strange glitch were other characters can access stages that they weren't originally meant to enter. They don't spawn where Sonic spawns however, potentially indicating that the levels were intended to be playable by these characters.
  • An unused Dragon Boss was found in the game's files. A demonstration can be found here
  • In the game's files, it is possible to find the game's characters saying things such as "Sonic Team" and "SEGA"
  • Speed Highway made an appearance in Sonic Generations.
  • Hot Shelter is the only level that cannot be played as Sonic
  • Achievements were recently introduced into the Steam version, however are not yet working as of September 2014. Online Leaderboards are also absent.
  • There are purple boarders on the game screen on the HD port, due to programming difficulties.
  • Online features were absent from the GameCube version, despite being included in the Dreamcast.
  • Cream the Rabbit makes multiple appearances, notably after the player leaves Casinopolis, and shortly after Amy's story begins.
  • NiGHTS makes a cameo in the Casinopolis stage.
  • Sonic Adventure was the first Sonic game to have downloadable content, see Sonic Adventure/DLC for a full list.

Beta[edit | edit source]

  • The game was originally titled Sonic RPG and was to be released on the Sega Saturn
  • It was originally intended for you to be able to play as Super Sonic during levels. Mods make this possible, however. [Note 2]
  • It was intended that Station Square would be connected, as you can see an untextured, hovering portion of the Casino Area in the debug mode [or by glitching out of the map, as demonstrated below].
  • The train in Station Square was originally meant to leave and return periodically, hence the "train to Station Square/Mystic Ruins is departing soon" dialogue.
  • Windy Valley was completely different in the Beta version, and there are mods which reconstruct it.
  • Amy and Big were originally playable in the level, potentially meaning all characters could play the stage.
  • Knuckles was originally able to uppercut. This was removed from the full game for unknown reasons.
  • Emerald Coast experienced minor changes.
  • The chase with Orca originally had no dash-pads.
  • In Big's level, Froggy was originally located in a secret passage.
