Sonic Forces soundtrack comes to CD!
Well, really, a 3 CD special set, because it had so much music in the game. The set is called "Sonic Forces: A Hero Will Rise". This is one of those thick plastic CD case things that holds all 3 with the 'page' piece in the middle. The cover is rather apocalyptic looking, with fire and destruction in the background. The hero cast is charging forward in the foreground, including Generic the OC. Eggman, Metal Sonic & Infinite are lurking behind the Forces logo in the middle.
A 3 CD set like this is great, because it lets you collect all the music at once instead of having to hunt things down. This became available in the summer of 2018.

It's seen on various Amazon sites (japan, US) and the European Sega Shop.
