Happy New Year! There’s so much more to come in 2025. Between new characters, modes, engine rewrites, and stages, we’re expecting this year to be one of Sonic World’s best. Stick around to see.

Many of our fans follow us through our Twitter, erroneously known as X. As policies are changing on that platform, they’re migrating.

For those who still want to follow DX updates, we will be crossposting on Bluesky and Mastodon!

We haven’t done this in a while!
While we have no content 100% ready to show yet from the scope expanding for V2.0, we thought we’d take time to check what everyone thinks of the current Sonic World experience and how to improve it.
Even if you haven’t touched World since 2017, please fill it out, so we can help make the game the best it can be.

What is this?

Sonic World is a sandbox, heavily moddable game styled after Sonic Adventure and Sonic Heroes that initially released in 2014. This is an online version of Release 9, the 2018 version of the game. The goal of this is to polish it enough to put it into Sonic World DX, the definitive version of Sonic World that pushes Blitz3D to its limits!

What’s included?

Release 9’s base gameplay has been mostly unaltered. All focus has been to include online play. It includes the following features:

• Tag Gamemode, tag others before time runs out.
• Hide and seek, one person is the seeker, the others hide
• Race mode lets you race to the finish, or fight others in rival missions
• PVP can be toggled by the host, alongside a countdown for races
• Spectate other players using F11 (Debug mode required)

This is an open beta, many bugs are present! Keep this in mind as you play,

How to play:

1. Download the game from the Google drive link (1st link)
2. a. If you downloaded the game yesterday, download the .exe file in the 2nd link and put it in your game folder
3. Launch the game and go through first time setup.
4. Go to options and find player name, type your name here. Also check your controls here and make sure they’re to your liking.
5. On the main menu, select online, then join.
6. Use your skill 2 binding (yellow button, defaults to s key/y button) to paste the i.p. address of the host (I will be hosting during this stream)
7. If all works, you should be auto-loaded in! Pause lets you restart if you get stuck or change your player.
8. team switch allows you to open chat. If you want to host yourself, you need to know port-forwarding. The port this game uses is Port 2222

After over 5 years of release, and after the 10th anniversary of the original Sonic World, the source code for Sonic World Release 9 is available and installation is documented!

Everything should be there to get the code up and running, except for the assets, which you should pull from an existing release 9 download.

After the drama with the original creator, developers started to spin off using the then-abandoned code, eventually becoming what Sonic World DX came today.

We hope making this open source that it may cause new developments with this, may it be additions to the game, fixes of long-running issues from the years old code, etc.

As Sonic World’s 10th anniversary approaches, team member has made a 2 hour documentary on the history of BlitzSonic up until Sonic World DX 1.2. A must-watch for anyone who played Sonic World or any 3D Sonic fangame between 2006-2015!

It contains comprehensive behind the scenes from every version of Sonic World and the most influential BlitzSonic fangames.

After a few months of silence, the next major version of Sonic World DX is here!

1.1.20 will be the next patch update.

We’ll be working towards adding compatibility for Legacy character mods and the animation system. this makes them way easier to port, only requiring minor text editing knowledge.

The model will still need minor changes to be compatible. Old movesets are NOT ported so most unique skill animations will have to be adjusted. Most mods using Sonic, and the President’s skillset will not be affected (Sonic would just need his throw animation deleted)

This does make porting Legacy mods much easier as you don’t need to worry about the added animations (victory, wait, mach, skydive, etc)

Want to know what mods this opens up opportunities for? Legacy mods can be found here: Link. Once 1.1.20 releases, we will supply a tutorial both on the Gamebanana and the supplied mod documentation. Our modding community means the World (ha) to us, so we hope this lets new fans and old replay older mods easier in this improved version of Sonic World.
