Checkpoint Zone acts as the HUB world for this mod. In here, you'll be able to alter match rules and advance settings, check the leaderboards for everyone's rankings, and just have fun running around with friends.
A cool feature of Checkpoint Zone that I wanted to point out is that you can now choose the same character as someone else! Meaning if you all wanted to play Sonic, now you can! No more rushing to get a character first because everyone can be exactly who they want!
Checkpoint Zone is a pretty decently sized HUB world and perhaps you don't want to have to run around everywhere just to set things up and enter a match. So to remedy this, Checkpoint Zone has a place you can warp to at any time called the Quick Warp. When in the Quick Warp, you'll be able to quickly travel to any major location in Checkpoint Zone! No longer will you have to run around doing errands just to set things up.
Whenever you're ready to actually start a match, go and pay a visit to Dr. Robotnik/Dr. Eggman. Use the controllers placed along the ceiling to choose your Level Select, then press the button to travel there. You'll be sent to the Level Select of your choice, waiting with loads of levels at your disposal to race in.
Oh! And heads up, certain Character mods should work. I can't guarantee that they all work, but just test them out. Some works while others don't. Stage mods, however, don't work.
