..here's some Knight Titans pictures and rules...if you squint a little...
Apparently the Imperial Knight Titan Kit will make all three? of the versions in the rules and the Imperial Knight Titan Codex will contain three armies in the book.
1st Army: Imperial Knights Army
2nd Army: Mechanicum Army
3rd Army: Freeblades Army (Mercs that can ally)
The fact that you'll be able to field these in multiples is going to make an army of them both expensive and impressive...
Here's an 'Action' shot...
Thoughts and comments are (as usual) most welcome.
