The missions lead us to believe that their is something really powerful trapped inside as if it were a prison. The landscape in front of the core has a dead elevator set up to go right into it as if there will be more levels inside.
We have all been waiting for quite a while now an I can't help but think if this thing will ever come into the game.
It probably wont come into the game.
Its just something to keep u hyped up for something thats never coming.
