Golden Gate: New World Front.

"Humanity's greatest weapon... is itself.

The Great Resource War reshaped the world, leaving the once-mighty United States of America a shadow of its former self. In 2077, the deadliest nuclear fallout in 40 years devastated the planet. From the ashes, the Remnants of America initiated Operation Reclaim, a bold campaign to recover their lost states and revive the union.

With strategic backing from the Greater European Union, America's rebuilding efforts gained new momentum. For the first time in decades, hope flickered within the battered heart of the Republic.

The People's Republic of California, weary from a brutal 15-year conflict with the New Republic of Texas, now faces an unfamiliar danger. A mysterious rift, codenamed The New Gate, has opened, its origin unknown, its purpose unclear.

Among those sent to investigate is Lieutenant James Lillian, a mobile suit pilot serving the United States Marine Corps. What awaits him beyond the Gate will shake the remnants of America... and the world they thought they knew.
