Build a base app

Maybe use the hypeSquad badges some more, and build a app with the theme of building a base.

 Use the badges shields as a team to choose of.
 
Use discords figures as figters/builders for this base, and chat along with other members with same shield as yours.

Make some mini clans with friends or random people you just meet along.
Build the base together or alone.

And then you can come with some other things
