There's another video making its way around with the devs talking about the game which shows a little more gameplay with the villains using their unique abilities. But it looks like those moves have a cooldown and firearms will be the primary means of doing damage.
Personally, I think I'd rather have the Superman game Rocksteady is rumored to have pitched but was denied. And so, they settled on this co-op looter-shooter. Players will have a Gear score and there will be Gear Sets because of course you need that in a Live Service.
All exactly the same!!
