In 1973, an invasion of aliens known as BETA upon Earth is driving human civilization into near collapse. Facing an enormous, unstoppable horde of enemy forces with weapons making aircraft almost useless, mankind developed large humanoid fighting machines called Tactical Surface Fighters and deployed them to defensive lines throughout the world. However, all these efforts could do was stall the BETA temporarily, and mankind is forced to abandon continental Eurasia. For the next 30 years, mankind finds itself bogged down in an endless war against the BETA without any hope of victory.
In 1998, BETA make landfall on the Empire of Japan's Kyushu Prefecture, and in short order the Imperial Capital of Kyoto is lost despite a desperate defense.
Fast-forward to 2001. As Imperial Japan defends the front lines of the Far East, it faces difficulties in the development of a next-generation TSF. A solution appears in the XFJ program, a joint development between the US and Japan, under the aegis of Project PROMINENCE, a UN-sponsored program intended to spur next-generation TSF development, using test pilots, scientists and engineers from around the world, gathering at Alaska's Yukon Base.
Enter 2nd Lieutenant Yuuya Bridges of the US Army, for whom assignment to the Project felt too much like a demotion, 1st Lieutenant Yui Takamura of the Imperial Royal Guards, head of the Japanese side of the XFJ program and Sole Survivor of her unit from the Battle of Kyoto, and the "Scarlet Sisters", 2nd Lieutenants Cryska Barchenowa and Inia Sestina of the Soviet Army. Coming together from different backgrounds, their respective pasts and meeting at Yukon, along with the other participants in Project PROMINENCE, will have important consequences for the Project, and indeed Yukon itself.
The visual novel adaptation and continuation was released for the PS3 and Xbox 360 in May 2013, with demos for each version available on both the PlayStation Network and Xbox Live Arcade. More information can be found here.
The PC version of the visual novel adaptation was released on September 26th, 2014.
This work contains examples of:
- Anyone Can Die:
- Zhar Battalion are destroyed due to combat losses from beta, friendly fire from bombers, and the Scarlet Twins. Although the Visual Novel continuation reveals that the Zhar battalion survived the arc.
- Leaked images from the Total Eclipse visual novel imply that Cryska dies at the end of the story. Those same images also invert the trope for someone already mentioned, as that person is seen, alive, at the site of Cryska's supposed grave-stone.
- Chekhov's Gun: Yui's watch, which she inherited from her father. In the Visual Novel, she's shot, but the bullet is stopped by her watch, which is made of the same metal as the Type-74 PB Blade.
