Greater Good Titan-Killer Titan Mech

Here's another re-upload of something else (free) that was uploaded by someone who vanished from the site.
This one comes in all nine configurations, and was originally designed for the Titanicus game. Hoever, there is a scaled folder included where all of them are upsized for normal 40K.
Given their original purpose, they are somewhat low on the details, but having a massive mech at all is better than no mech.
