## About The Pull Request

![obraz](https://github.com/user-attachments/assets/b7840360-db17-42e5-8c23-d161e59acf8f)
Woah! Best sprite showcase of 2024!


Note: Those goggles, unlike the ones that factions have, do NOT have a
sechud. They are just fancy sunglasses.

<!-- Describe The Pull Request. Please be sure every change is
documented or this can delay review and even discourage maintainers from
merging your PR! -->

## Why It's Good For The Game
- Probably good to have them seperated, just like how inteq did it.
- Indie sec drip.
- I REALLY want this for the #3380.

<!-- Please add a short description of why you think these changes would
benefit the game. If you can't justify it in words, it might not be
worth adding. -->

/:cl:

<!-- Both :cl:'s are required for the changelog to work! You can put
your name to the right of the first :cl: if you want to overwrite your
GitHub username as author ingame. -->
<!-- You can use multiple of the same prefix (they're only used for the
icon ingame) and delete the unneeded ones. Despite some of the tags,
changelogs should generally represent how a player might be affected by
the changes rather than a summary of the PR's contents. -->
