Crusader
Early versions that were fun but the 'shotgun' fire attack looked a bit too splash damage
One of the first heavy tanks I designed for the game, the Crusader. We had https://www.artstation.com/mrpink77 doing some extra work for us at the very start of the project and he did some fun work for this guy early on - and while this tank ended up with more classic treads I did reuse the four-legged track look later for the Mammoth.
