SAGE 2022 - Demo Sonic Unite (SAGE '22 DEMO)

General Information



Sonic Unite is a 2D Sonic Fangame built in Unity, Made by the fans, For the fans

Sonic Unite aims to be a high quality (to the best of my ability) fangame that adds new concepts while keeping core Sonic gameplay elements from the original trilogy. as such, the aim is to not reinvent the wheel. Game physics are accurate and should just feel like a continuation of any other sonic game with a few QOL enchancements and exciting new level ideas. i want to release the game sometime this year to coincide with the 30th anniversary games.

Before you download. Sonic Unite has its own patcher/updater used to keep the game up to date. For SAGE. the game is already predownloaded and ready to go. however it is highly recommended to run the updater before playing to download any hotfixes or patches for the best experiance

Development officially started February 2022 but work dates back to September 2021, i aim to complete the entire project sometime by the end of the year. Check detailed progress reports below




While the project doesnt have a dedicated place for updates, I mainly post updates to my Twitter and Youtube under #sonicunite. if demand is high enough i may make a central location for updates. AKA a seperate social account or Discord server.

Sonic Unite was developed in Unity (Dont let that put you off) i chose Unity because i have the most experiance with the engine and have made games in the past for it. The game uses a highly modified version of the Sonic Realms Engine found here

Music for the game is pulled from various community artists from newgrounds with permission (yes i'm as surprised as much as you are that it's still a thing) this was done to spotlight some lesser known artists while also providing an amazing retro soundtrack.

Some graphics and spritework reference their original but some are drawn by my wonderful best friend nephele. She's super cool and talented and her artwork really shines

Sonic Unite also features Discord RPC integration. check it out below

FINALLY The meat and bones of the project. Before you even begin the game. Sonic Unite has a patcher which is used to keep the game up to date. please read the notice box for more information.

In Sonic Unite. You admire the crash landing of the Death Egg directly after the events of Sonic and Knuckles. However, Your victory is short lived as the doctor has one last ace up his sleeve. While also kidnapping tails in the process. Travel through 13 acts across six zones to save your buddy and defeat the doc once and for all.

In the Demo. Certian stages are unavailable as they are still work in progress. also, little to no boss fights have been implemented at this time. Other than this. the content is fully playable and i hope you enjoy what is there.

For Completionists. After beating the game. A super hard level will be available to play. HyperNova. This is a brutal take on a Sonic Level and only the brave of heart will be able to complete it. Good luck and embrace the challenge.

Sonic Unite has the ability to load image data to be used as a custom level. This feature is in beta. for more information. please check the documentation here

Sonic Unite has always been and will always be a passion project of mine. not only is it fun to develop (sometimes) but its a learning experiance. While i've made games in unity before. you can always learn something new. contributing to SAGE for the first time is a fun experiance too.

I hope you enjoy playing my game as much as i enjoyed making it
