Star Wars Rise of Species

This is an earth conquered by alien civilization, and mankind has entered a chaotic post-civilization era. The swords of the Space Marines from the outer realm shine for a light-year, the mysterious psykers drive the 10,000-ton giant ships, and the roots of strange alien creatures lurk in the deep sea reaching the core of the earth. Combining forbidden martial arts with mecha tactics, thousands of alien races lurk beneath their feet, leading humanity to once again reach the top of the interstellar species.
