"The past few days have brought with them an increase in enemy activity in the areas bordering one of our solar power conversion plants. We believe an attack is imminent."

"This plant is the sole provider of power to other facilities we operate in the area and is vital to our interests."

"Efforts are under way to reinforce the plant's defenses, but the key power hookup for the newly installed gun batteries has yet to be completed."

"The power hookup requires linking the gun batteries to the solar collectors. Prevent the collectors from being destroyed while final preparations are made."



Deathgrip: "Facility in sight. Commencing attack."

Emma: "AC identified. It's Longspear."

Gunner: "Raven, we're still working on the power hookup."

Gunner: "We'll provide backup as soon as the guns are online."

Gunner: "Power hookup complete. Stay clear of the guns Raven."

Deathgrip: "Gaaahhhh...!"


The main threat here lies in Deathgrip. Though he only has a bazooka and a blade, he's alarmingly accurate with his shots and also possesses quite a bit of durability. It's best to use weapons with high DPS against him. However, should you take too long in defeating him, the gun turrets will be fully hooked up to power and will fire on him. The helicopters will continually spawn as long as Deathgrip is not defeated, which is why it's recommended to get rid of him quicker.

Once Deathgrip is gone, just finish up the remaining helicopters in the level (or you can just let the gun turrets take care of them if you took too long in fighting Deathgrip).
