The Reservoir

From the start, climb the slimy hill. To the right, slash slime covering a ladder. Climb it, then climb over to kill 2 pigs for 4 Meat.

Unlock the door. Facing the windmill, head left to find another Labyrinth puzzle. Enter the windmill, look right, and check the barrel for a picture of the Rare Animal (the pig from Luiza's).

Use the Typewriter on the table if desired. Head left, note the sign, and go down the stairs. Follow the linear path to the elevator and interact with the yellow switch to go down.

Upon exiting the elevator, head right into a clearing. Look for tracks leading to a tunnel on the left. Look up at the ceiling to find a shining Crystal Fragment. Stab/slash it to collect it.

Proceed through the tunnel to a dead end. Look left for a passage and go up the stairs. At the top, head left past the rug and approach the green slime. Squeeze through to obtain the Arms Flask after a scene.

Head back down the stairs and out of the tunnel. The previous path is blocked, but the barred gate on the left is now open. Go through to return outside.

Head right down the slope. Smash the yellow Barrel on the left for Handgun ammo.

Note the Treasure past the water; you'll return for it later. Enter the small wooden shack. Inside, turn right to find a note, 'The Reservoir and Giant Fish (File)', on the table. A boat is docked here, but requires a key from the Mine area.

Turn back and head up the hill into the mine area. Look left for wooden stairs.

Go up the stairs, then right at the top. Check the nearby barrel for Handgun ammo. Head to the opposite side of the stairs. Slash the yellow tape on wooden beams to the right to create a path. Climb down the ladder and go behind it to find a smashable Barrel containing Lei.

Prepare for Lycan enemies. Reload weapons. You can strategically use a mine and headshots. After defeating them, explore for a Herb.

Walk past the tree and into the water on the left. Find Handgun ammo in the boat. Exit the water and smash the yellow Barrel on the dock for Lei. Turn around and smash another yellow Barrel on the left for more Lei.

Enter the small shack to find the Boat Key. Several Lycans will attack upon entering, including an Armored Variant that drops in front of the door. Explosive weapons are effective. You can use the wooden door on the left to barricade yourself or run away if low on ammo/supplies. Defeating them may yield Crystal Skulls.

Return to the boat. Use the Boat Key to enter. Head straight into the large cave, then make your way to the other side. A Giant Fish will swim by.

Enter the smaller cave and disembark at the dock. Move towards the tent, then turn right before it to find a branching path. Follow this path to a small pool with 2 fish. Kill them for 4 Fish Meat.

Head back and enter the green tent to trigger a scene.

As soon as you regain control, run up the steps away from the Giant Fish until you reach dry land. Drop down to the path below, head right, and enter The Gatehouse.

Inside The Gatehouse, find a console to lower water levels, but power is needed. A poster explains you need to use a crank to operate windmills and then return to use the switch. The Duke and a Typewriter are also here. Save your game and visit the Merchant. Leave via the door between the entrance and the Duke's room. Head right.
