Super Robot Taisen: Original Generation 2

The year is 187 S.E. It has been six months since the DC War against the Divine Crusaders and the L5 Campaign against the aliens known as the Aerogaters. In the aftermath, the Earth Federation Army (EFA) was forced to restructure due to the severe casualties it suffered, even among its leaders. Brian Midcrid, once President of the United Colonies, was elected as the new Earth Federation President. Previously, he had disclosed information on the L5 Conflict to the Federal Assembly. This disclosure, later called "The Tokyo Manifest," revealed the existence of extraterrestrials who posed a threat to the survival of mankind. Since then, President Midcrid has announced the Aegis Project, a plan to rebuild and re-arm the EFA. He has asked for solidarity among all the inhabitants of Earth. In the name of the project, he began to fortify the planet by developing new humanoid mechs and mass-producing them. However, trouble lurks in the shadows... Remnants of the Divine Crusaders, a group once led by Dr. Bian Zoldark, along with individuals in the Federal government and the EFA, are scheming to establish a military state... And the forces working in the shadows, as well as the mysterious entities called "Einsts," will plunge the human race into even greater depths of chaos...
