Chapter 5 and almost at the end of the PC action adventure game, Resident Evil 4. With the help of this walkthrough, you'll be duking out with the enemy at breakneck speed!
The beginning always has no enemies so don't worry about that. Run around the island until you reach a fork in the path. To the left are items and the other side leads to a wooden bridge. Put out the light before jumping the gap and approaching the buildings. Be ready to fight your enemies from this point onwards. One of which sports a chaingun. Be careful and don't lure him out in the open. Keep a healthy distance before you snipe them down and getting on ahead.
Now head upstairs and to the left of the locked door, there's a laser light to activate. Now as its turned out, head to the NW building and get up the ladder. Rotate a mirror to reflect the laser beam to make it hit the reflector SE and direct that beam into the light's receptor so its to the right of the locked door. Now since its connected, the door will rise. Head to the tunnel and be ready to dodge the boulder being pushed at you and be careful of the crossbow enemy. Once done, climb up the ladder to the next area. Once there, get to the right and enter a small cave tunnel. There will be enemies you can lure. So once there, pick at their remains and then hop back out of the building
From here enemies will converge NE. Target them with your sniper scope one at a time, then get along the hillside path. Now, take the left path leading to a narrow tunnel. Take out the enemy and and head back down the path. Now go on south and you'll get to the door. Be careful of enemies and shoot down this flaming enemy that will burst out of an oven. Beyond this, is a doorway to the next part of the building. Now make your way down the hall and then take out the enemies before collecting items. Now go back upstairs and get to the door to the east ( you can hear Ashley by now). Get going to the merchant room with an automatic door. This will open and close with attacks launched at you. Use the grenade to blow the enemies away. In the next area, there's a save point to the west and unlock the door. From there, continue up the steps to the second floor.
Now head SE and enter a lab with a body on the operating table. Use the control panel to opent he door to the eat (rotate the arrows so they point the connection from the top to bottom) Grab items and the Freezer Card Key. Now before you leave, the Regenerator will come through the door. Blast the leg with a shotgun and past him to exit the door and re-enter the first hall.
You can't kill these people so just cripple them, now head north and unlock it using the card key and enter the freezer. There's a card key re-writer there so you can unlock the garbage disposal unit. Then turn the valve to shut the freezing mechanism off. There's another valve you can turn and opening up a small door with the Infrared Scope.
