When the assets are uploaded on Dec 19th:

Everyone gets the base assets to play with.

You will ALSO  get a Mystery folder with a story, clues, images, and text files... the story talks about some things that happened and scene that was found.... study those and you can figure out codes, and those codes get you (or are) passwords for zip files with more assets.

It's just a fun way to skirt around the hardcore mode of the base assets.   You CAN do it for fun, and still do the hardcore mode.

This year is quite an interesting puzzle!  I like it a lot, heh.
