Zero Hour | Walkthrough Homefront: The Revolution Guide
Once you reach the meeting place, take the rocket launcher from the table and go towards the meeting place, for whom where you received the alarm. Move through the depopulated areas of Philadelphia, until you reach the place where you will meet a fierce resistance from the Koreans. Your task is to kill the soldiers attacking Ned's station. Place yourself in the place seen on the screenshot, where you will have a good vantage point (real fair play, shooting their backs before they can react). The moment the armored car appear, use your rocket launcher to destroy it and clear the way to the armory.
In the further part of the mission you will have to place yourself in one of two visible places on the screen. I advise to use the right one, because it will provide better visibility on the incoming Koreans. Once you eliminate a number of them, and receive new orders, go to the car to escape the danger zone.
After an unsuccessful escape, you will have to deal with Goliath, a heavily armored vehicle, which only purpose is to kill enemies. The best tactics is to return to the previous building, where you eliminated the enemies coming out of the container, and hide behind a wall. Prepare the rocket launcher and wait for a right moment to fire.
Warning! It may happen that one or two shots won't be enough to destroy Goliath, so have some pipe bombs or other explosive materials prepared.
Once you end the fight, go to the Goliath's remains, and take it's "brain", which needs to be taken to the main metro hideout of the resistance. Once you arrive, get inside the train, visible on the screenshot, to talk with the doctor. The task will be successful after a talk with the main leader of the resistance, and you'll receive 2000$
