Muv-Luv Alternative: Total Eclipse

In 1973, aliens called BETA-Beings of Extra Terrestrial origin that are Adversaries of humanity-invaded Earth. Over the next three decades, they took over most of Eurasia, wiping out billions. To counter their strange tactics, humans developed a new kind of weapon: the Tactical Surface Fighter (TSF),a mobile mechanical humanoid. By 2001, elite pilots from across the globe gather at a UN base in Alaska called Yukon for the Prominence Project, a joint Russian-American initiative to develop the next generation of TSFs. Their mission is to test experimental units, sometimes even facing them against each other in trials.
