Muv Luv Alternative: Desparation

What once was a storied and vast area of Humanity has become ground zero for the BETA invasion. Nearly the entirety of the north and much of the western parts of the continent were part of the USSR, a collection of Soviet Republics forming a conglomerate of a country. To the southeast, there are the remnants of both the countries of India and China. The entire region once held a significant portion of the earth's population, but the BETA have mostly pushed Humanity out of all but the Indonesian Peninsula and the furthest northeastern part of mainland Asia, the last remnants of Manchurian and Kamchatka Russia (USSR), leaving the few refugees and surviving militaries, without their own countries to return to. The landmass and ecology has been irreparably changed since the BETA, leaving mostly just a barren, mountainous wasteland and their Hives dotting the continent.
