Titan and hunters

The year is 2147. Giant creatures known as Titans emerge from dimensional Rifts across Earth, threatening humanity's survival. Protected by colossal war machines called Titan Hunters, mankind fights a desperate war against an enemy it barely understands. But as the Titans evolve and new truths emerge, humanity begins to question whether the monsters are invaders... or refugees fleeing something far worse. Titans are the Kaiju and hunters are the robots Play as a piolet, a titan/Kaiju or a civilian Sandbox (Something like Pacific rim)
