General Information
IMPORTANT NOTICE: If you are interested in this project, you can help me by talking to my Discord DMS (username is Akurio64#3823) or on our Discord server (the server is inactive as of now for an unknown reason tho). I may program decently, but I could use some help with coding. It would help me make this project come true.
Story


This game is also supposed to be a prequel to Sonic Adventure even if it would be revealed at the end, but the game contains modern-like stuff, like an E-Series prototype, an Egg Carrier prototype (Egg Behemoth), and Robotnik starting to wear military clothes during the Final Story.
About the game
In this demo, you have five lives to defeat demo versions of some game bosses for each story (except Knuckles because I have no idea how to imagine all these Meta bosses). This chart shows which zones have their boss. I made this demo for a new and fresh version of Outbound to fix up the bad SAGE '20 version.
- Heaven Shore: (In South Island) A heavenly beach Sonic and friends had gone in for vacations.
- Events:
- Sonic: Sonic goes to the west because the Badniks in charge of finding the Time Stones were going in that direction. Sonic does not know what is happening, but he knows Robotnik is up for no good. When passing the second act, Sonic will find a rail track that goes to Sunset Park
- Tails: Tails go to the east. He will fight Fang, who reveals that he will stop Tails from saving his friends because he was hired by Robotnik to do so. When he is defeated, he will run away. Tails tell Sonic about Fang and then follows Fang to the Casino Night Zone.
- Knuckles: Knuckles chases Meta and in Act 2, he will meet Meta and then fight her. When defeated, Meta gets rid of Knuckles by using the Phantom Ruby and making him go to Collision Chaos.
- Sonic: Sonic goes to the west because the Badniks in charge of finding the Time Stones were going in that direction. Sonic does not know what is happening, but he knows Robotnik is up for no good. When passing the second act, Sonic will find a rail track that goes to Sunset Park
- Events:
- First Zones:
- Sunset Park: (In South Island) That zone from Sonic Triple Trouble. Sonic will fight Fang and then stay on the train to arrive at Star Light.
- Casino Night: (In West-Side Island) We all know that iconic zone… Tails will fight Robotnik. Robotnik then uses the Phantom Ruby to make Tails go in the past, to Forest Dawn Zone.
- Collision Chaos: (In Little Planet) Knuckles is in Little Planet now. He will fight Meta and when she is defeated, Meta will activate a trap that kicks Knuckles to Wacky Workbench.
- Sunset Park: (In South Island) That zone from Sonic Triple Trouble. Sonic will fight Fang and then stay on the train to arrive at Star Light.
- Second Zones:
- Star Light: (In South Island) Sonic fights Robotnik and then Sonic finds a virtual headset that sends him to Robotnik's virtual world, the Virtual Engine (ver. 2.39)
- Forest Dawn: (In West-side Island) Inspired by Wood Zone, who would have been a present version of Casino Night Zone (there would have been time travel in Sonic 2 before it was put in Sonic CD). Forest Dawn Zone is the past version of Casino Night Zone before Robotnik started building that casino. Tails will also fight Fang (he travelled in time thanks to Robotnik) in this zone. When Fang is defeated, Tails gets back to time and finds himself in Aquatic Ruin.
- Wacky Workbench: (In Little Planet): Knuckles fight Meta and when she is defeated, Knuckles will find a pipe that sends him to Relic Ruins.
- Star Light: (In South Island) Sonic fights Robotnik and then Sonic finds a virtual headset that sends him to Robotnik's virtual world, the Virtual Engine (ver. 2.39)
- Third Zones:
- Virtual Engine (2.39): (a virtual world) Sonic infiltrates the system to enter Robotnik's main computer network and destroy it. He will have to fight an antivirus Robotnik created to stop Sonic. After crashing the server, Sonic leaves Star Light and finds the train that sent him to Star Light, taking it to arrive at Techno Turret.
- Aquatic Ruin: (In West-side Island) Tails will fight Fang in his Sea Fox and after defeating Fang, Tails will find an underwater entrance to Techno Turret.
- Relic Ruins: (In Little Planet) Inspired by the scrapped zone in Sonic CD. Instead of fighting Meta, Knuckles will fight Robotnik in his Egg Bike. When Robotnik is defeated, Knuckles will take his bike and ride to West-side Island via the chains keeping Little Planet chained.
- Virtual Engine (2.39): (a virtual world) Sonic infiltrates the system to enter Robotnik's main computer network and destroy it. He will have to fight an antivirus Robotnik created to stop Sonic. After crashing the server, Sonic leaves Star Light and finds the train that sent him to Star Light, taking it to arrive at Techno Turret.
- Techno Turret: (In West-side Island) The biggest structure ever made on Earth (tower). Robotnik built it to connect the land to Little Planet. Our heroes will not be able to destroy the structure, but they will discover something important: the existence of something more powerful than the Phantom Ruby.
Events:- Sonic and Tails: In Act 2, Sonic will meet Tails in the middle of the level. They will fight E-010 Proto, the first version of the E-Series. Sonic and Tails will discover the existence of the God Ruby by watching Robotnik's plans about it. He sends Sonic and Tails to different places with the Phantom Ruby.
- Knuckles: Knuckles arrived at the Techno Turret after stealing Robotnik’s bike and driving to the Egg Factory. He will meet Sonic and Tails for Act 1 and then leave. The miniboss he will fight is Robotnik with his factory machines. The big boss is Meta. When defeated, Meta will attack Knuckles by surprise and hit him so hard he gets kicked to South Island, in the Egg Garden.
- Sonic and Tails: In Act 2, Sonic will meet Tails in the middle of the level. They will fight E-010 Proto, the first version of the E-Series. Sonic and Tails will discover the existence of the God Ruby by watching Robotnik's plans about it. He sends Sonic and Tails to different places with the Phantom Ruby.
- Fourth Zones:
- Peelout Park: (In South Island) A brand new zone that is theme park-themed. Sonic will fight Robotnik and then Sonic will find a new entrance to Marble Zone discovered by Robotnik.
- Ice Cap: (In Angel Island) We all know Ice Cap. Tails will fight Fang and when done, he will go to Launch Base via a pipe because Tails saw a giant airship starting to launch.
- Egg Garden: (In South Island) This was the Sleeping Egg Zone before Robotnik decided to upgrade the zone. A tribute to Whitehead's first zone. Knuckles will fight Meta. She destroys the land Knuckles was standing in and makes him fall into Pipe Madness.
- Peelout Park: (In South Island) A brand new zone that is theme park-themed. Sonic will fight Robotnik and then Sonic will find a new entrance to Marble Zone discovered by Robotnik.
- Fifth Zones:
- Marble Zone: (In South Island) It is an ancient underground complex, flooded with boiling lava pools. After the Robotnik battle, Sonic finds an exit but it was a trap sending Sonic to a bottomless trench.
- Launch Base: (In Angel Island) In Sonic 3, Sonic and Tails entered the Launch Base to stop the Death Egg. Now Tails will go stop the Egg Behemoth. Unfortunately, Tails was too late and Fang unleashes one of the many Egg Bombers inside the Egg Behemoth. Tails need to go to the highest section of Angel Island to jump on the Egg Behemoth.
- Pipe Madness: (In South Island) A large pipe system made by Robotnik to get rid of wastes and circulate water (can you believe it, he did something good). Meta and Knuckles will fight each other by climbing pipes. Knuckles will then find a pipe that leads to Labyrinth Zone.
- Marble Zone: (In South Island) It is an ancient underground complex, flooded with boiling lava pools. After the Robotnik battle, Sonic finds an exit but it was a trap sending Sonic to a bottomless trench.
- Sixth Zones:
- Treacherous Trench: (In South Island) This is a legendary trench only mentioned in legends, but Robotnik found it and is digging to find the entrance of the Time Palace. When Sonic will fight Robotnik, he will dig a hole making Sonic fall (like shown in the boss fight). In the end, Sonic falls at the entrance of the Time Palace.
- Volcanic Inferno: (In Angel Island) This is the largest mountain on all of Angel Island, an active volcano. (It's the volcano where Lava Reef is inside) Tails will fight Meta in an epic showdown until the Egg Behemoth (just so you know, Fang is the one who is commanding the Egg Behemoth) arrives to attack Tails. Fortunately, Tails entered the airship before.
- Labyrinth Zone: (in South Island) One known as the pain zone, now it is no longer the pain zone. Knuckles will face off against the Egg Behemoth on its way to the Volcanic Inferno because Fang detected Knuckles and started attacking. Knuckles will see Tails entering the airship, so he continues his path to the Sky Sanctuary Orb
- Treacherous Trench: (In South Island) This is a legendary trench only mentioned in legends, but Robotnik found it and is digging to find the entrance of the Time Palace. When Sonic will fight Robotnik, he will dig a hole making Sonic fall (like shown in the boss fight). In the end, Sonic falls at the entrance of the Time Palace.
- Final Zones:
- Time Palace: (time vortex) This is the place where Sonic goes when he collects the Time Stones. It is also the final chance to collect the Time Stones. Sonic will face off Robotnik on his new Egg Walker. The Egg Walker's destruction sends Sonic to the real dimension.
- Egg Shell: (in the Egg Behemoth) Tails did not enter the core of the Egg Behemoth, but merely one of its defence systems of it (yes these defence systems are gigantic). Tails will face off against Fang in his combat plane. When Tails destroys the plane, Fang falls to his death until Tails saves him, even if Fang is his enemy. Tails ask for Fang's help but he refuses and leaves. Tails decide to use his Tornado to go to the Egg Behemoth.
- Sky Sanctuary: (In Angel Island) Knuckles knows the Master Emerald is located in Sky Sanctuary. He will find it, but Meta then uses the Master Emerald to turn Super (like Mecha in Sonic & Knuckles, but harder). Meta's defeat makes her go out of control and she destroys Sky Sanctuary (you could say she's gone haywire). Knuckles jumps out of Sky Sanctuary with the Master Emerald hoping he lands on something safe.
- Time Palace: (time vortex) This is the place where Sonic goes when he collects the Time Stones. It is also the final chance to collect the Time Stones. Sonic will face off Robotnik on his new Egg Walker. The Egg Walker's destruction sends Sonic to the real dimension.
- The epilogue of the character's stories: Sonic teleported to the sky, but Tails saved him while flying. Knuckles falls from the sky and Tails saves him too. The three will go to the Egg Behemoth (with a Sky Chase-themed level). Fang follows them.
Plans for the final version
In the full game, players would have three different stories similar to Sonic Adventure, you could choose between the Sonic Story, the Tails' Story, or the Knuckles' Story. Each character will meet the other during the game. After finishing each story, the Final Story is unlocked. Also, I may remove Virtual Engine and replace it with Robotropolis, making Egg Behemoth the final zone.
Sonic's Story




1. Finish the game with every Time Stone and you unlock Super form, playable in the completed save or Free Play.
2. Collect the Super Emeralds which can unlock Super form. At the end of the true ending, Hyper form (Hyper Sonic, Nine Tails, and Seismic Knuckles) is unlocked in the completed save or Free Play
The Meta Saga

Meta, what about her?
.Meta originally was going to be a genetic creation made by Robotnik. She would be supposed to have the DNA of Sonic, Tails, and Knuckles. But since we listened to your complaints about Meta's backstory and her design, we decided to scrap the idea. Now we have two choices:
-
- Meta is simply an ultimate version of Metal Sonic created with the Phantom Ruby. Meta is built to copy Sonic, Tails, and Knuckles. Meta is also sentient but blindly follows Robotnik. Meta is still sentient enough to discover Robotnik's lies at the end of the Meta Saga.
