Attack on Titan Wiki:Achievements and Badges

Achievements are a way to encourage people to collaborate on the  and reward that hard work. There are many different types of achievements, and every time you reach one, you will accumulate points and get a Badge visible in your profile. If you are one of the top 19 users of the Wiki by number of points, you will also get a place in our Leaderboard.

Rules

 * This feature is intended to encourage people to help on the Wiki, not to make a high number of insignificant edits or vandalize pages just to get a prize. Any user detected doing this could be blocked, losing also all their points and badges and their position in the ranking (if any).
 * All edits made before the implementation of the feature (March 29th, 2015) are not counted for the achievements, only those made after it was enabled.
 * Activity on the forum and edits in template pages are not counted either.
 * Only users registered in the Wiki participate, not anonymous users. If you are not registered yet, then create an account.

Secret
There are also other badges and achievements, but they are hidden and you have to look for them by your own. Perhaps, if you are persistent and have a bit of luck, you can catch those elusive badges.
