We have an all-out-brawl between the Blackwatchers, the Hunters, and us in the military depot. This fight is tough, so I hope you got used to the controls. Consuming a hunter will earn you the claw power, which you will need to tear through these guys. Consume some more to initiate another wave. Keep slashing and eventually you will be prompted to destroy the fuel tanks. Do it. Consume a hunter if you need health.
