Loop Hero

Much like the description suggests, you are required to unlock and generate every tile over the course of all your runs (unlocking the tile without placing it does not count). You will need to alter your "deck" of tiles by selecting the icon in the top left when prepping for an expedition. Most of them you will get through natural play but the list of tiles is as below:

(Note: all tiles will be organized by placement type)
