Daglob, I'd love to take a look at all of that.
Randomdays, I need to do some reading there. Not much in the way of files or images but might be nice to see what names come up.
Epimethee, great sharp lines there. What algorithm are you using?
I've got a classic entry today: The Freedom Force Pre-Order Bonus Disc!
Download the disc ISO from the Internet Archive here.Bonus characters? How does that work? Let's run FFBonus.exe and find out.

Wait? It's just Iron-Ox, Blackbird, and Supercollider? Aren't they already in the game?
Let's hit "Install Characters" and see what happens.

Wow, that was extremely quick. Turns out all it does is find your init.py and add a single line.

If you're new to the game, you can be forgiven for not recognizing this. The line enabling the characters is pre-included in the GOG release. (not sure about Steam) The workaround of adding this line was extremely well known online back in the day. To the point where I didn't realize there was an official path at all.
So is there anything else on this disc? Now's a great time to show off Internet Archive's ability to browse inside ISO files.
https://ia801503.us.archive.org/view_archive.php?archive=/4/items/freedom-force-bonus-cd/Freedom%20Force%20Bonus%20CD.ISOAs you can see in the menu above, the disc contains the Character Tool. In that folder is also the meshes and skins for the various basic custom heroes as well as Blackbird, Iron-OX, and Supercollider. They're the exact same files that come with the final game install. Pretty useless if this was released alongside the game. Anybody remember if it was delivered before release? The file dates are at most a month before the final game coming out.
The browse artwork button opens up a web browser with a mini FF site embedded on the disc. I've cloned it to my own website here:
http://freedomforce.ewzzy.com/bonuscd/FF_BONUS.HTMSome of the javascript doesn't seem to work, so if you'd like to see the 3D rendered wallpapers
here's an Imgur gallery. All of the
character concept artwork is in a gallery here.
Pretty fun inclusion I'm sure got some use back in the day is the Web Site Kit. It's got some screenshots, the logo, and even the FF comic text font.
Grab that here:

Among the concept art (which I will go way way deeper into another time) are highlights like Supercollider's retractable wheels:

A Twiggy version of the Civilian Female:

Hints that the Ice Queens might have been a singular character named Mrs Frost (fanny pack included):

Please, take a look through yourselves and see what highlights you find. I'm working on some retro magazine content now. You won't believe some of what's coming.
