During this phase, zombies will come and try to attack your guns so cover your teammates on the guns. Man these guns and eliminate the Bombers trying to shoot at you. It costs 750 Jolts to use a Artillery Gun. There are three Artillery guns: one in the Bunker, Bunker 3, and the Overlook area. Head toward the Bunker area from the U-Boat Pen area. This next step is not required to complete at this very moment but it is highly recommended to do so. Kill him by shooting the tanks on his back and you will move on to the next step. Once this door opens, a very tanky flame thrower zombie will drop down. After all 3 valves are turned on, the door where the corpse is hanging will open, gruesomely tearing the corpse in half. The flames will randomly light up other parts of the platform so keep an eye out! Once the flames in front of the valves are extinguished, turn on the valves. The three valves are located in the corners of the U-Boat Pen platform and will initially be blocked off by flames on the ground. The next phase is to avoid the fires and turn on the three valves. Kill the first two bomber zombies you see but on the third bomber zombie, chuck your grenades at it. When you enter the mine cart (costs 250 Jolts to ride) there will be bomber zombies on the tracks. Note: Be sure to have plenty of grenades for this next encounter! (Sticky Lethal Grenades seem to work the best) Make sure the lever is toggled on to STRAND. There is a lever in front of the mine cart that can be toggled to change the destination of the mine cart. To find the secret room, you must go to the Bunker location and ride the mine cart at Bunker 1 down to the Beach.

Note: To harvest zombies with the Ripsaw Gun, get a running start and hold your melee button to lunge and harvest a zombie. The Ripsaw Gun costs 500 Jolts to obtain and shoots out Saw blades. This will take about 20 zombies and will ultimately give you the Ripsaw Gun. Once the Saw is back on the table, you must kill zombies near the table to take their souls and feed the Saw Gun. When the meter shows up, take the Saw back to the work table in the U-Boat Pen hallway.
