To top it all off, Battle for Earth's storyline will put players toe-to-toe with Brainiac's Prime Avatars before they go up against the big bad Brainiac himself. Heroes will be fighting, obviously, for the defense of Earth, while villains will want to take Brainiac out of the picture because, hey, why let someone else destroy the world when you can do it yourself?
The new DLC pack will hit the Marketplace on March 13th, though it will, of course, be free to Legendary members. So hone your skills and prepare for the final showdown; the fate of the Earth is in your hands.
