In 1972, the skies over Hanoi became the battleground for what is remembered as the "Dien Bien Phu in the air," a significant chapter in the Vietnam War, specifically during the intense period known as Operation Linebacker II. This operation, launched by the United States from December 18 to December 30, 1972, marked the final major military campaign against the Democratic Republic of Vietnam. It was initiated following the collapse of the Paris Peace Conference due to irreconcilable differences between the US and the Democratic Republic of Vietnam over the terms of the peace agreement.

The video game "Hanoi 12 Days and Nights," developed by Pirex Games, seeks to encapsulate this pivotal moment in history. Focused on the theme of revolution, the game aims to recreate the fierce aerial conflict where the people of Hanoi stood resilient against the formidable might of the US B-52 bombers. This "devilish war" in the skies is a testament to the determination and spirit of the Vietnamese people. The culmination of these 12 days of intense combat led to the US Government agreeing to the Paris Agreement, bringing a semblance of peace to North Vietnam by the end of December 1972.

On the American side, Operation Linebacker II was not just a military strategy but a desperate attempt to force a favorable outcome at the negotiation table. Known as the "Dien Bien Phu in the air," this campaign underscored the last efforts of the United States in the Vietnam War, highlighting the strategic and human challenges faced by both sides in this conflict.
