- Defeat Cornelius
The first is a battle against Cornelius Werner, who operates with the same tactics in the previous mission. With better equipment, you should still be able to inflict damage as expected in the previous missions.
- Locate the power source
You will need to head outside, finding the only path out in the general direction of the first waypoint.
- Outside, near where you encounter two ballistic wanzers. Specifically, they're in the third gap between mid-path cover counting from the wanzer pair.
