Militarized Zone

Talk to Colonel Hardy to start this mission. Head to the base and kill the Wrestler. Proceed inside the base and find all sirens. While the sirens are blazing, expect a continuous flow of infected. You'll also encounter a special wrestler-type enemy called the walking carcass.

Take it out and follow the trails leading to the sirens. You can climb the ladder and disable the sirens by hand or you can shoot them if you have the gun. Be careful of the wrestlers in the area as well.

After taking out the sirens, approach the gate and locate the explosives in the area that you can use to bring it down. You'll find the explosives in the southwest storage area. Blow the gate open and enter the military base.

Once inside, make your way to the basement and turn on the generator. Backtrack to the stairs and go upstairs this time. Enter the room to the right and head to the next room. A fire will break out so open the door to the left and take out the zombies ahead.

Follow the trail and activate the extinguisher. Make your way to a few more rooms and kill the Meat Thrower in the comm room. Activate the comms to complete the quest.
