2010’s Sonic Colours was a Nintendo Wii release that featured a resolution equivalent to 480p. Compared to Ultimate, graphics have been improved to work in a resolution equivalent to 4K. A change of lighting also gave a new feel to the levels.
Rival Rush mode
Go head-to-head with Metal Sonic to unlock rewards.

Players can run against Metal Sonic in Rival Rush, which will allow them to unlock rewards. Sonic Studio’s Takashi Iizuka has reassured fans that the Game Land mode isn’t going to be replaced by Rival Rush mode, with Rival Rush being just another mode for fans to sink their time into.
Park Tokens and Customization
Head to the store and use park tokens to unlock unique boosts, auras, shoes and gloves for Sonic.

Ultimate will also come equipped with a store. Players can use park tokens to purchase customizables for Sonic, like new sneakers, gloves and boost auras.
Jade Ghost
Transform Sonic, fly around and pass through solid objects to reach hidden areas.

Originally from Team Sonic Racing, the Jade Ghost wisp was added to Sonic Colours Ultimate. In it, players will be able to use the wisp to go through walls to reach brand new hidden areas.
Customizable Controls
Customize your controls to find a layout that suits your play style.

Players will be able to customize Sonic Colors Ultimate’s controls, something that was only available in PC releases of Sonic games.
Tails Save
Find a Tails Save and be taken back to safety if you need to be rescued.

As shown in previous reports, if the player (equipped with a Tails Save) falls in a bottomless pit, they will be saved by Tails and dropped off at the nearest point before the player’s fall. The feature replaces the life system.
100 Count Ring
Collect a 100 Count Ring to gain temporary invincibility and boost your score after each level.

Returning from the Wii version of Sonic Unleashed, the 100 Count Ring will have a new purpose. Not only it’ll give players 100 rings, but will also grant them temporary invincibility and will help the player’s score.
Music
Fully remixed soundtrack to set the pace while you put an end to Dr. Eggman’s evil plan.
Sonic Official
The remaster will contain a brand new remixed soundtrack for all levels. The player can also opt to change to the original version as well.
Sonic Colours Ultimate will be released 7 September on PC, PlayStation 4, Nintendo Switch, and Xbox One.
