Well, this is certainly a unique tank design, and definitely one f the most heavily armed, although it is nearly impossibly to tell exactly how large this thing really is. Maybe it's the camera angle, but it looks small to me. Like, probably 5 to 6 meters in length. Although, I think that feels also comes from the tread design. If I were designing this, I would've left the treads as single-tracked, as opposed to double-wide. Mainly because, while the segmented, hinged drive-train is unique and would certainly improve on mobility issues present in traditional tanks, the extra width means extra friction that whatever system is used to turn must overcome to do the actual turning. Also, you might consider lengthening the tracks so that they lead the vehicle, and making them deeper to give the vehicle greater clearance for potential hazards and obstacles. Also, the leading edges of of tank treads are usually fairly large, so that the engine doesn't have to strain with using a smaller surface to begin an angled ascent (steep hill)... Unless this is intended as an urban vehicle, which I kinda get the feeling that it is, given the lack of a large main gun, and several smaller batteries that have the appearance of energy-weapon apertures. What with the hexagonal and square barrels. Also, am I seeing a pair of radioisotope thermoelectric generator (RTG's) near the rear (self-contained nuclear generators)?
To me it feels like this tank is cleverly designed. There are many great features such as the independent track movement, and the assortment of smaller guns and missiles, not to mention all the support systems I see. However, to me it feels quite exposed, like a collection of systems were stacked on it, and that well placed firepower could disable a substantial number of critical weapons and such. Also it is too tall. For any tank as big as a fatboy, it would have to be lower to the ground and more heavily armoured, as it would be impossible to hide behind cover with those high points. And it would also require substantially more protection, especially around the joints. Also, too much space is taken up by smaller guns. You could remove a few smaller weapons that don't matter too much, and make the four bigger and deadlier, as fatboys are inherently land battleships. Finally, I would personally have added a big laser. But that doesn't matter very much.
This only lacks in one respect: Fulfilling the original Fatboy's largest flaw which is the health-to-firepower ratio. Yes the old Fatboy was a glass cannon artillery unit, however it had a nasty tendency to get destroyed by any other land experimental in direct combat, due to its very underwhelming armour and health. The thing is that anything running under the shield (i.e. T3 Armoured/Heavy/Siege Assault Bots) in typical SupCom numbers means the unit is finished within seconds. The Fatboy needed an armour upgrade more than shield (though that would be nice too) or firepower upgrades. Mobility would be nice, but the Fatboy gets by and is balanced with other Experimentals in that respect.
I believe that the Fatboy should concentrate its guns along the centerline to offer better overall firepower (or with two turrets side by side in the front and then two turrets behind them that are superfiring i.e. fire over those) ro concentrate forward arc firepower. The rear would be unit manufacturing, air staging, and two missile (air or ground toggle) turrets on the rear track pods. The front track pods would mount a set of lighter turrets. This would allow all the firepower to be brought to bear within the forward 120-degree arc, and you can order the unit to drive in reverse when retreating, that would make it much easier to use.
Doomsday has obviously never experienced the epicness of Supreme Commander, Fatboys are what 200 meters wide and 250 long? The Fatboy 3 would probably be similar sized (or it would be too easy to hit with arty or arty splash)...
Critique below is flawed... possibly stupid. Friction comment has no basis in fact, physics not doomsday's strong-point clearly. Not sure what he is asking re: RTG?( he seems to think he is an engineer too and that these RTG things are real and his specialty!) Possibly this is a young child so I don't wish to belittle his opinion, it might have lasting effects on his psyche.
Anyway: I assume this intended to be a very large weapon; a moving fortress of some kind; wide tracks doubled enhances this sense of scale (and might even prevent this from sinking into the battlefield if such a thing were feasible) I like the textures used, the layout of the mechanized fortress seems creative and yet nearly practical. I would like to see this rendering in a battlescape (this might also quiet foolishness about the vehicle being 5 m long).
urban? jeebus! it is a neighbourhood... what's he figure it goes up stairs? I know it is hard to say a critique is unfair (for risk of seeming petty) but nonsense should be ignored. Good star rating though.
The Fatboy Tank is a mobile FACTORY that can produce units. I've played supreme Commander before, and i can tell you: this thing is HUGE!
The 4 Big guns mounted on the turret are the artillery guns. Their main role is to bombard bases from afar. Even those that are beyond the line of sight. (These guys were my favorite unit and i spam them against my enemies: built 2 or 3 of them at a time, and once I've built like... a dozen-or two-of them keep them moving towards the enemy, slow and steady as we bombard along... and once we get there, the whole place is empty-many were blasted from long range) And they are more than capable of bombarding even while moving.
Game? The artist's description mentions nothing of this design being for a game. (Although, the description really mentions nothing at all) Still, my critique is no less valid. This design has a few things in common with the French Saint-Chamond tank or First World War, such as a low-slung body and relatively short treads that are shorter than the body of the tank. Those aren't good things over variable terrains.
