Well, it's engines will try to "resist" turning over. It's engines work to keep your hull in a stable position. If you fall of a bridge or something, the engines will still try to keep the hull in a stable position. I believe that's what they meant. :)

The devs said a few things about Ares in some livestream. It will be affected by mines, since it "doesn't fly really high".About rotating the hull, they said you will have to rotate your camera. Basically, your turret. And, you know when you move with one of the hulls forwards, your shots go a little up? In this hull's case, your shots will go down. Just a little, though. And when falling, it's engines "compensate" so the hull doesn't turn over. You still will be able to turn it over, but only with a lot of effort. OD! You already know it's going to be offensive. They said it has to do something with the cannon in the front. And that it will maybe be able to shoot through walls. That what I know, I hope you appreciate it :)

Oh my God... is that an XT rocket?
