Unlock the New Park area, explore the paths, and raid the hidden secret zone for custom parts.
Once you defeat Ray Kon, the pathway to the New Park opens up. Proceed North-West to enter the new map zone. Battle the local bladers in this zone to clear the arena table, gaining substantial character XP.
Search the East boundary wall of the New Park. Interacting with the broken fence panel reveals a hidden pathway leading into the Secret Zone. Tucked away in the bushes are chests containing high-level customizable attack rings. Collect these immediately to upgrade Tyson's offensive capability.
