Attack on Titan: Spartan Assault (Looking for Beta Readers)

Humanity is under siege. For 107 years, they have been forced to cower behind their walls in the face of the greatest threat they have ever known; the Titans. But, in their darkest hour, help arrives from the stars. John-117 may be able to change the tide of war, but new threats lay beyond the horizon, and it's not just the flesh eating giants he has to worry about. (Ch 2 Updated)
