Homefront is a first-person shooter game developed by Kaos Studios and published by THQ. In the fourth mission The Wall, the player will once again use the Goliath to push through the enemy forces. But the heavy vehicle has to be protected against the several soldiers equipped with RPGs and ready to shoot at the Goliath.

1. Follow Connor and Rianna outside to see Oasis and its inhabitants killed. Boone is also dead.
2. Follow them across the street When you step into the wide area between the houses, you will be attacked by the enemies. Take cover behind the house on the left and take the sniper rifle. First, take care of the soldiers with RPGs on the second floor of the house. Then, kill the remaining soldiers one by one. Stay in cover and do not step out.
3. When the Humvee appears, use the targeter to call the Goliath and destroy the enemy's vehicle.
4. The Goliath will then attack the other enemies. Follow it and stay behind. Enemies with RPG will shoot at it but you have to kill them before they do that. When you see a marker on your screen, quickly find the RPG soldier on a roof and kill him.
5. The Goliath will destroy the barricade and allow you to move further. In the next area, shoot at the RPG soldiers on the rooof and use the targeter to kill the remaining Korean soldiers.
6. A tank will appear from the enemy's side. The Goliath will make a hole in the house on the left. Follow it inside and cross the house.
7. Follow Rianna to the side of the house and target the tank. The Goliath will get on the street and destroy it.
8. Once the Goliath is fixed, follow Connor. You will witness the attack of a city. Continue with Connor.
9. You will meet other members of the Resistance. Follow Connor to the battlefield. Stay in cover behind the walls and take the Koreans down with your sniper. Run to the control panel of the barricade, crouch and keep pushing the action button until the barricade goes down.
10. Regroup with Connor and follow him inside the building on the right side of the street.
11. Break the door open and kill the enemies in slow motion. Shoot at the ones coming in the room and take cover to kill the three soldiers with RPG. Use the sniper rifle. They are on the second floor of three buildings.
12. Lower the second barricade and regroup with your team. Follow Rianna upstairs and pick the RPG. Shoot at the Goliath when it is near the main gate. The vehicle will explode, creating a way for you.
13. Get on the Humvee and shoot at the enemies while you are getting out of the base.
