In the year 1973, alien species known as BETA (Beings of Extra Terrestrial origin which is Adversary of human race) invaded Earth, after wiping out human settlements on the Moon. 28 years later, they have already conquered and laid waste to most of the Eurasian continent and reduced the global population to one billion. As previous military strategies and tactics were catastrophically ineffective against the BETA, the human race began to develop piloted robot weapons called "Tactical Surface Fighters" (TSFs).
Thus in 2001, elite pilots around the world start to gather at a UN base in Alaska named Yukon to participate in the Prominence Project. This project is a multinational effort handled by the United Nations on research and development of TSFs against BETA, and the job of the pilots are to test the prototypes, which occasionally involves pitting one against another.
Second Lieutenant Yuuya Bridges is a maverick and top pilot in the US armed services with a disdain towards things Japan, due to his Japanese father leaving him and his mother. Assigned to Yukon by exasperated superiors keen on sending him away, among pilots of various nationalities, he may come to grips with his blood heritage...
So is anyone excited for this besides me? I'm a huge fan of the Muv Luv series. (Though many of you may recognize it's prequel. Kimi ga Nozomu Eien, which has had a major anime series already.) But yeah, this is pretty much a must see if you're into war dramas that involve fighting against an alien species that humanity has no hope against. Though, this is just a spin off of the original Alternative. Which still isn't confirmed for an anime yet.
