Template:Need Proof This article pertains to the beta elements from Sonic Adventure.

Title

Sonic Adventure was originally titled Sonic RPG, to be released on the Sega Saturn. However, by the time the Dreamcast came out, the developers realized they would need a better system that could handle the creature Chaos.

Characters

Classic characters

Sega originally wanted the Classic forms of the characters in the game, but decided to fully use the Dreamcast's capabilities, and ultimately re-designed Sonic, Tails, Knuckles, Amy, and Eggman. Models would be the same as Sonic R.

E-Series

E-103 Delta, E-104 Epsilon, E-105 Zeta originally had the same color as E-102 Gamma (except their laser-cannons that are different). This can confirm in the E-102 Gamma tutorial.

Super Sonic

Like in previous games, Super Sonic was originally going to be playable in regular stages.

It is possible this was removed for more bug fixes, as the game was a little bit rushed at the end of development. There is an unused audio file within the game's data in which Tikal explains how to transform into Super Sonic.

Stages

Emerald Coast

Originally in Emerald Coast when Sonic goes to the quays where is chased by an orca there were double loops, and when he is chased by an orca, in the platforms there were no dash-pannels.

Windy Valley

Windy Valley was a completely different stage in early development. There are a few screenshots showing Tails flying around in an unknown location and also some gameplay footage showing Sonic and the rest of the cast walking around in this unfamiliar environment. Even the final release's intro video and Amy's very first cutscene are showing pictures of this place which was later proven to be a beta version of Windy Valley. Remnants of the stage were found within the files of the Sonic Adventure Auto-demo. Attempts to launch the level within the game itself weren't successful yet because of missing files which are causing the game's crash when trying to do so. Converting the level geometry itself was possible and since then the level was ported to Sonic Generations as a mod. This geometry seems to be the beta version of the third section of Windy Valley which was partially used as a beta Chao Garden as well. Pre-release footage also shows that the first section had it's own beta version as well and was partially re-cycled for the final design. Amy and Big were originally playable in this stage.

Speed Highway

The "Goin' Down" section originally there weren't helicopters. The "At Dawn" section of Speed Highway was fairly different from the final release. The section was redesigned and a few parts were removed completely for yet unknown reasons.

Eggmans robots

Little purple enemies

Those little purple enemies of Final Egg were originally purple and yellow.

Unused Duck enemy

In the Sonic Adventure Auto-demo, An unused duck enemy was found in Final Egg.

Moves

Uppercut

UppercutSA

Knuckles using the uppercut.

Knuckles was going to use use the uppercut but then was scrapped for unknown reasons.

Others

Sky Chase Dragon

Sonic Adventure - Sky Chase Act 1 - Screenshot - (3)

The scrapped Sky Chase boss.

There was an unused mini-boss of a mechanical twin-headed dragon that was going to be a mini-boss in both acts of Sky Chase. It is invisible, but it follows the Tornado in flight without damaging it.

Loading screen

The the loading screen was originally in the middle of the screen and had the title game in black and white.

Chaos Emeralds

Classic Chaos Emeralds

The classic designs of the Chaos Emeralds.

The Chaos Emerals originally had their prior games design.

Station Square

Originally, each area of Station Square was going to be completely connected, some leftover of this attempt can still be found within the final release if the player meets certain conditions and activates debug mode (an untextured floorless version of the Casino Area can be accessed from Station Square's coastal area which loads itself as a part of it which suggests that at some point in development the Station Square hub area was supposed to be loaded in it's entirety).  Also, more pedestrians were going to roam around the city.


Timed Train

The train was possibly going to leave and arrive without the player's boarding, but this was possibly removed because the areas would overlap.

Rocket

There was going to be a rocket in Sonic's gameplay.

Trivia
