I noted this in the documentation:
In Gamification, all badges are persistent and cumulative. Unlike the level badges in Jive, users keep their
level badges in Gamification and add them to other badges they've collected from missions or from previous
I don't understand how this works and have not seen it in our community where gamification has been enabled for five months. People reach a new level and it does not give them a badge, although an image appears next to their avatar. That image is replaced by the image for the next level when they move up.
Believe this was in reference to having multiple missions in a series of 'levels'
