Summary
Gustave Wylder is a former MEC Soldier.
A deserter of XCOM who lives his life far away from any life he can manage, surviving off of scavenging, the occasional trade from wandering resistance or survivors outside of ADVENT's control. He's spent the better half of his days since his desertion doing everything in his power to stay off the grid and radar of ADVENT or XCOM.
However, just as the day he abandoned his duty, nothing stays the same forever. He just wished it didn't take him nearly breaking a few ribs to start the cycle.

Summary
Many believe that the galaxy is full of unknown possibilities. Ores and resources untouched, lands undiscovered, species undocumented, though no one would have thought of A FUCKING WAR BETWEEN THE ELDERS OF THE PSI SYSTEM AND THE REST OF THE GALAXY! This conflict has been going on for decades, destroying entire civilizations and races of people, ruining ecosystems to hellish degrees, and dragging other nations, kingdoms, and governments into this war. Everything was going fine on Earth, though the sightings from NASA exploring the stars have been unsettling. Then They came, Sectoids, Mutions, Floaters, and those damn Lids. They invaded Earth, taking over the governments under one banner. ADVENT. The Commander of the XCOM project(The Reader) was captured during this. Twenty years later, a few years after Remnant and the Galactic Republic have joined the Psionic Wars against the Elders and Advent and a week before Unification Day, Team RWBY and Delta Squad of the COG have been sent to Earth to aid XCOM and free the Commander. Team RWBY have also been sent to find the two teams that were sent before them, Team CFVY and Team SSSN. Can these Huntresses and Soldiers help save the day, or will the War be prolonged even more.
