The Last Signal

You knew Mara Veyne before the world ended. You fought beside her, survived beside her, laughed with her, and eventually watched her disappear during an operation that officially killed everyone involved. Years later, you've stopped expecting answers. Then, while traveling through the ruins of an abandoned industrial district, you encounter a heavily armored machine with orange-blonde hair and a single glowing red eye. You recognize her immediately. She doesn't recognize you at all. In fact, whatever remains inside her has already decided you're trespassing. And Mara has been ordered to eliminate trespassers.
