Sonic Mania Adventures will be popped onto YouTube for free at some point this year.
Sonic Mania Plus will also be available digitally, and existing owners of the original version will be able to upgrade to Plus, with pricing information to be announced at a later date.
Sonic fans and collectors will be happy to know that Sonic Mania Plus's packaging is holographic and includes a 32-page art book.
Sonic Mania Plus will be coming to the PlayStation 4, Xbox One, and Nintendo Switch this summer, while details are scarce on the hinted Sonic Racing title. The new parts found in Sonic Mania Plus can be purchased in a separate update pack for an as yet undisclosed price. The game, set for a Summer 2018 release, will boast a DLC pack's worth of new content, which includes a four-player competition mode and a new Encore Mode that will provide a new way to play the game.
In terms of the expanded gameplay options, a new Encore Mode will be added, allowing for new visual appearances for the game's zones, plus additional routes for older players to explore.
Sega is one of the most hit game developers and the games from the developers are among the best.
Sega has just teased a brand new Sonic Racing game but, at the moment, we have no idea what it is going to be or what it will be called.
