Super Robot Taisen Compact 2

After the One Year War (Mobile Suit Gundam), the Earth has returned to a state of partial peace. However, insidious forces both inside and outside our world are awakening, and the flames of war are fanning again. Under the name of hunting down the remnants of Zeon forces, the Earth Federation forms the Titans, a special military group. Meanwhile, Zeon reforms itself into Neo Zeon (Zeta Gundam), on a mining asteroid known as Axis. On Earth, the former forces of Dr. Hell (Mazinger Z) and the Dinosaur Empire (Getter Robo) begin to rampage. From outer space, the Vega Empire initiates an invasion. Only the very few remaining battalions band together to combat these new threats, both on Earth or in its orbit. Nobody knew, however, that these events were a prelude to a conflict that would encompass the entire galaxy.
