Medals

Medals are collected by completing certain conditions.

When a medal is complete you are given access to its reward. Collect the reward by locating the medal in the Medal List (found on the main menu) and selecting the reward button. A little present image is shown next to medal with uncollected rewards.

Some items can only be obtained through completing medals.
Also note after completing a medal it may unlock a new medal to complete. Sometimes medals may chain unlock up to 5 times.
