Sonic Frontiers isn’t technically an open-world game, what with the Starfall Islands divided into five different “open zone” regions. Nevertheless, each has much to do, from fishing to roaming bosses. But how many puzzles and challenges are on each?
The starting region, Kronos Island, has about 25 different Challenges and an additional “mystery” to solve. Ares Island, the second that players will travel to, has 29 Challenges and two unique puzzles. The third region is Chaos Island, which offers 24 Challenges and a cool pinball mini-game. Rhea Island is the fourth, but doesn’t sport any Challenges – instead, players have to disable six towers.
The map is small and easy to circumnavigate, so you shouldn’t have any issues finding each tower. Finally, the fifth region Ouranos Island has 27 Challenges. For each Challenge’s location and how to complete them, check out the videos below by Stickman Guides.
Cyber Space Portal Locations
In addition to Challenges, each region also has Cyber Space levels. These lead to more linear, 3D Sonic-style levels based on previous games. Green Hill, Sky Sanctuary, Chemical Plant, and many more make appearances. However, in addition to collecting Portal Gears to enter said levels, you also need to find the actual Portals.
Here are the locations for all of the Cyber Space Portals, starting with Kronos Island:
- Cyber Space Portal 1-1 – On the southeastern part of the smaller land mass.
- Cyber Space Portal 1-2 – On the east side of the smaller land mass.
- Cyber Space Portal 1-3 – Southern part of the larger land mass.
- Cyber Space Portal 1-4 – Slightly north above Portal 1-3, almost in the center of the larger land mass.
- Cyber Space Portal 1-5 – Slightly north above Portal 1-4.
