1972's Hanoi-Dien Bien Phu Victory in the Air, also known as Operation Linebacker II.

The game "Hanoi 12 Days and Nights" was created by Pirex Games. This revolutionary title aims to recreate a segment of the historic "Dien Bien Phu in the Air"—the fierce defense mounted by the people of Hanoi against the U.S. imperialists' massive B-52 bombing campaign. By late December 1972, the U.S. government was compelled to sign the Paris Agreement, restoring peace to North Vietnam.

Known in the United States as Operation Linebacker II, the "Dien Bien Phu in the Air" campaign was America's final major military operation against the Democratic Republic of Vietnam during the Vietnam War. It took place from December 18 to December 30, 1972, following the collapse of the Paris peace talks due to irreconcilable disagreements on the terms of the agreement between the two sides.
