If you want to uncover the whole Sonic Frontiers Kronos Island map and activate the fast travels in the same area, then you must also complete Challenge M-023.
However, this Challenge is time-gated, and you must move pretty fast, so I guess it’s a good thing that you are Sonic.
Even so, you should follow the guide below and make sure you don’t encounter any difficulties while completing the M-023 Challenge.
Sonic Frontiers Challenge M-023 Location
First, you must learn where to find this Challenge, and with the following map, you’ll get the general location.
As you can see, you must make your way to the northwestern corner of the Kronos Island area.
Look for the M-023 sign west of the big field of stone pillars highlighted blue.
There should also be an hourglass next to this Challenge sign as another point of reference.
How To Complete M-023 Challenge On Kronos Island
To start this Challenge, you must approach the hourglass and press the X button on your Xbox controller.
Doing so will start a short cutscene showing you the location of four glowing blue balls, as shown in the following image.
To complete this Challenge, you must use your Cyloop skill on each ball until the timer runs out.
I suggest you start with the ball on the bottom left, next to the big rock.
Once near this blue sphere, hold the Y button, also on Xbox, and make a circle around the orb to make it disappear.
Then go to the ball to the far right and repeat the process to make this one disappear as well.
Two more orbs remain, so go to the one closest to you and use the Cyloop skill on it.
Finally, go to the ball on the far left, work your magic, and you should be done.
Don’t forget you are on a timer but don’t worry too much because the 50 seconds should be more than enough.
Once you’ve dealt with the last blue orb, you complete the Sonic Frontiers Kronos Island Challenge M-023, so congratulations!
