The Tunnels — Boulders & the Mine Elevator

You arrive in the stone tunnels beneath the courtyard. Ignore the first door and continue straight ahead to find an item box and typewriter. Deposit everything except the Shotgun, its ammo, and a blue-herb mix, then head back to that first door.

A massive boulder blocks the path to the right, so take the left door instead into a room with a cargo elevator and control panel. Open the small hatch to take the Shaft, and grab a handgun magazine on the elevator floor and another near the door. Cross through the right door.

You find Bravo team leader Enrico Marini, badly hurt. He warns you that S.T.A.R.S. has been set up — there's a traitor in the ranks — before someone you never see shoots him dead mid-sentence. Take the Hexagonal Crank he was holding and head back toward the boulder, watching for Hunters along the way.

The boulder you dodged opens two new paths. Grab shotgun shells where it used to sit, then head through the opening it made — a giant spider, Black Tiger, attacks here. Clear it with the Shotgun, then use your Combat Knife to cut through the cobwebs sealing the other door. Inside, take the herbs on the left and the Courtyard B1 Map.

Cross the right-hand door and use the crank again — this time turn it three full rotations to release the boulder, then sprint for the left-hand opening to avoid getting crushed. At the back, grab a First Aid Kit.

A gate opens, granting a metal part — combine it with the Shaft you're carrying.

Deposit the First Aid Kit and your knife at the item box. Examine the combined Shaft; rotating it reveals a sequence of Roman numerals — memorize the order.

Insert the shaft into the elevator's control panel and press the numbers in the exact order you just saw. Power returns to the mine.

Before you ride down, Barry catches up and descends with you. Distant moans echo below; Barry says he'll stay put and keep watch. Ahead, past a small item box and staircase you can ignore for now, Lisa Trevor appears again.

Grab the ammunition stacked on some crates, then push the large crate onto the cargo lift and press the button to send it across. Head back to Barry, watching for Lisa on the way.

Once you're back, Barry rides the elevator up — and leaves you behind. It's hard not to wonder: is he the traitor Enrico warned you about?

Head downstairs to find the crate you sent over earlier sitting by a trash compactor. Push it in and break it open to reveal the Broken Flamethrower. Take it, then return to the item box to drop off spent ammunition before heading back toward Lisa's area.

With the clamps held open, continue through the door beyond.

You reach a room lit by candles and lined with dolls. Follow the path along the water to a bedroom covered in photographs — take the dagger from the bed and a second Jewelry Box nearby (a different one from the box you opened earlier with the Red Gem). Head upstairs, grab the herbs, and cross through the door ahead.
