Sonic Racing: Crossworlds introduces fast-paced kart racing to a vibrant, dynamic world with imaginative circuits, customizable cars, and a diverse cast of characters.
This game encourages experimentation with machines, gadget plates, and racing tactics by combining personalization and strategy, in contrast to classic racing games.

The different speed settings in Sonic Racing: CrossWorld make it so that each race feels unique and challenging.
At the beginning of the game, there are only three speed options that are available to you: Normal, High, and Sonic.
Using intuition, we know that high speed will offer a faster racing experience than normal, while sonic speed will provide you with an even greater challenge and a faster feeling.
You’ll be able to select the three speeds from the Grand Prix Mode, while in the Time Trial Mode, only Sonic Speed is available.
You’ll also be able to unlock two more speed modes later on in the game, like the Supersonic Speed and Mirror Sonic. To get the supersonic speed you’ll need to win seven Grand Prix at Sonic Speed.
But this must exclude the Secret Grand Prix and Crossworld Grand Prix, meaning that the first seven main Grand Prix races will count.
You may be confused about which Grand Prix you’ll be able to access, as at the start, only six are available. When you complete all six, you’ll also unlock the Egg Grand Prix. Completing it will unlock the Supersonic Speed.
After winning all seven (winning as in beating your rival) credits roll followed by a cut scene with Dondon Pa.
Supersonic speed will be significantly faster than Sonic Speed. Whereas Mirror Sonic Speed will flip the track horizontally on the Y axis, making it much more difficult for you to play.
When you unlock the two mods will add greater depth and challenge to the game.
