Instructions
Load your saved "Patapon 2" game file.
Access the Evolution Map from the main menu.
Highlight any available node on the Evolution Map using the directional pad. Press "X" to select a node. Each node represents a basic type of Patapon unit. Press "X" a second time on any node to transform one of your Patapon units of the selected type into a "Rarepon." This is a special unit with better stats and unique moves.
Deploy your Rarepons in story battles to increase their levels. When a Rarepon reaches level 5, it will open up any adjacent nodes on the Evolution Map.
Continue to transform Patapon units into their respective Rarepon forms. Deploy each Rarepon until it reaches level 5 as you make your way across the Evolution Map.
