Godzilla vs PS4 Campaign missions question

So by now we all know that the new Godzilla Vs for PS4 will allow the player to play as every Monster in the game. But how will this work in terms of the campaign (single player) missions? In the previous game, you played as Godzilla (and Godzilla alone) destorying reactors to get the G-Energy they contained. Will it still be the same mission for the other monsters? Will the other monsters just have Mini-Campaigns that invole fighting other monsters and destroying buildings? Will SpaceGodzilla get his own Campaign (he seems like one of the main attractions (for lack of a better word) of the new game)? Any Ideas or Info? I not, I guess we'll have to wait for more details or until the Game is released.

And for record, I did not see the Ps4 Game thread...so sorry about that.
