SAGE 2020 - Demo Sonic Arcus - SAGE 2020 Alpha Build


Please start by resetting the save data from the options menu. That will fix some of the glitches.
An update will be up in the next few hours!


( NOTICE: This is a very early version of the frameworks and by no mean represents how the final result will be )
Sonic Arcus is Unity Sonic Framework heavily based on Sonic Unleashed. Its aim is to provide users with the majority of tools to recreate their favorite levels from the boost era, import original and fan-made levels from Unleashed and Generations, and so on.

This demo includes 3 hub worlds as voted on twitter ( Eggmanland, Spagonia, Apots ), 4 playable levels ( Apotos act 1 HD, Apotos Act 1 SD, and two gameland levels) and test level

The game has support for PS4 and XBOX ONE controllers ( for ps4 enable it in steam and use it to open the game or use DS4 Windows )

This demo is by no mean a complete product but is here to showcase the capabilities of the framework and most importantly for you to share your feedback and ideas.

Download v0.5.3 : (508 MB .zip )
If the game gets stuck in the title screen please reset your save data in the options!


PS: All content is subject to changes in the future. This is an early version and does not reflect the performance of the final product in any way. Every future version will be more optimized and polished.

I don't have anything to say right now in terms of criticism, but this looks ABSOLUTELY AMAZING.
I only have few problems theirs no bounce and no boosting in the cities also I collected all 15 emblems ( I think ) and i can't play the other stages
Awesome Work.
Sonic Arcus is good Sonic Unleashed port/fangame for pc.
I wait for New updates, new levels and night levels.
I keep my fingers crossed for the further development of Sonic Arcus :)
Oh okay and Tofuu should know that I downloaded this for one of my friends who subscribed to him :1
Aw, man. Could you just release a framework, not the demo? It looks like it's in its's final stage of dev already!
