From the control room, head outside and check the cabinet to your right for Shotgun Shells. Continue and look to the right to spot some Handgun Ammo next to the tires on the right. Use the Crank to raise the bridge and go over it. Move to the end of the path to reach a fork.
Head right and into the hut. There's Chem Fluid and two Wooden Boxes inside, along with a Mr. Everywhere Statue hidden underneath the net.
Continue to the end of the walkway and collect the content of the Wooden Box and use the Crank a second time to create another bridge pathway. You can also find some MAG Ammo on the left, near the white cages.
As you continue, several Molded will appear. It's best to simply rush over the bridge to the door at the far end, which is a Safe Room. Entering will dissolve all Molded enemies instantly, saving you a lot of time and ammunition. Inside you can find a Wooden Box, Psychostimulants, Flame Rounds x3, Chem Fluid, Separating Agent, Stong Chem Fluid on the shelf above the save point, a Herb and Shotgun Shells near the stairs.
Organize your inventory and put away the Crank, but bring along the D-Series Head and Arm. Also bring plenty of restoratives, your M21 Shotgun and Grenade Launcher with some Flame Rounds and, if you have crafted some, Neuro Rounds. Save your game and go upstairs, where you’ll find Mia and Zoe. A short scene plays and then you’re up against Mutated Jack.
BOSS FIGHT - MUTATED JACK
The boss fight isn’t too difficult as long as you stay on the run. Only Jack’s ‘eyeballs’ can be harmed/destroyed, the rest of his body is impenetrable. Flame Rounds work well, but so does the M21 Shotgun. Run around and go up the area, switching between levels several times. When it seems like you’ve hit all eyeballs, have Jack come up to the upper level and quickly drop down. You might be able to spot more eyeballs on his belly. A well-aimed Flame Round (or alternatively Shotgun Blast) should do the trick. Jack will attack one last time, so shoot his eye a few times and he’ll be done for, especially when you inject the serum.
Outside you’ll have to make a choice. Choose whoever you want and a scene will play, taking you to the next area, the Wrecked Ship.
