Eggman destroys all the platforms but the one you're standing on, he just blows up & you have beat the game. Eggman then catches fire and he destroys the platforms so be careful not to be in the middle of a platform. Repeat these steps until his life level is zero.

The DX Pack on its own retails for 10,897 Yen (99 USD) and is available for PS4 and Switch. The DX Pack can be bought separate from the Anniversary Pack or with the Anniversary pack. This will reduce his life level and put Sonic back on the platform. Exclusive to the Ebten SEGA Store, which as mentioned requires a proxy service like ZenMarket, there is also a Sonic Colors Ultimate DX Pack. Once you get close enough to hit him, do a double jump to hit Dr. If you do jump on the disc, the disc takes you back to where Dr. Eggman as possible and when he shoots the disc you have to try and jump on the disc. The fifth time you hit him, he goes to the side of the platform again, but this time he shoots little discs that have spikes on the edge. When you go to the side, he shoots the laser to the side so do it quick. The fourth time you hit him, he shoots the little lasers, then he goes to the side of the platform and he shoots lasers until he gets close enough to hit Sonic. Each time he comes up, wait until you see the green circles, then jump on the green circles until you get close enough to hit Dr. Keep doing double jumps until you get to Dr. Once he comes back up you have to wait until you see a few little green circles. When you do that again, he gets a giant laser - just do not be in the middle of the laser. When he pops up and comes out of the black hole, you do a double jump. Super Sonic (after the player finishes the game with all characters) Metal Sonic (after the player gets all 130 emblems on the DX version).
