| A secret passage will open. | (2)

First things first, you'll need to jump down the hole. Once you land, look around. To your left, you'll find a BATTERY PACK. To your right, there's a LAST BOOK, VOL. 1. Make sure to check the pages of that book for a MEDAL OF EAGLE – you don't want to miss that!

After that, you'll enter what's marked as the GRAVE area. You'll see a grave right away. Interact with it (press the button) and grab the diaries. Then, head on down.

You'll then find yourself in an UNDERGROUND HALLWAY. Your goal here is simple: run straight down this hallway towards the door at the very end. Keep an eye out for Spiders – they can be a nasty surprise if you're not ready.

Continue into UNDERGROUND HALLWAY 2. Keep running down the hall until you pass through a gate. You'll come across a lever. Go ahead and pull it. Once that's done, take the only other door you see in this room.

Now you're in the KITCHEN. From here, you've got two choices: you can head through the door directly across from where Jill is standing, which leads to the KENNETH ROOM, or you can make your way to the elevator.

If you choose to go to the KENNETH ROOM, you'll climb up the stairs and find yourself back in the KENNETH ROOM, but it's now called the KENNETH F HALL. Be prepared, because there's a Sweeper here. Remember these guys from Resident Evil CODE: Veronica X? They're basically Hunters with poison attacks. Your best bet is to take it down with Acid Rounds or your Magnum. The door to the F HALL will also get torn down, so the room's name changes. Head into the F HALL section and make your way to the LEFT STAIRS.

You'll then reach the LEFT STAIRS SAVE ROOM. This is a good spot to unload any excess items you're carrying and, of course, save your game. Once you're ready, exit the room.

Head back up the stairs. You'll want to unlock the door that's nearest to the left of the stairs.

This leads you to the YELLOW GEM ROOM. This room is a bit of a head-scratcher with a puzzle, but first, grab the GRENADE SHELLS located near the right deer head.

Now for the RED GEM PUZZLE. Look for the drawer cabinets near the center table. You'll need to push these cabinets towards the deer heads nearby. After that, use the switch next to the door to turn off the lights. Now, here's the tricky part: don't try to pull the YELLOW GEMSTONE from the deer head just yet. Instead, QUICKLY RUN TO THE OTHER DEER HEAD and grab the RED GEMSTONE. If you're running low on item space, you might need to drop something first.
