There are some interesting items to your left, including explosive bottles.
verify that you’ve taken at least one bottle.
Choose a pistol from your inventory and head over to the main gate.
Use the pistol to destroy a new padlock (screen) and enter museum grounds carefully.
Make a few steps forward.
You are going to be attacked by a fissure monster and this time you’ll have to defeat it.
check that you’re ready and that you’re in FPP view.
You could also try moving back, however it won’t be necessary.
The fissure monster will approach you from the left.
Start shooting at the ground and one of the bullets should eventually reach its destination.
You’ll notice this instantly, because the monster will catch on fire (screen).
You may finally start moving towards the museum building.
Once you’re there, turn right and jump over a small gap (screen).
It shouldn’t be a problem.
Now you’ll have to find a small fuse box.
Use the pistol to pop launch the box and press the action key.
Thankfully, you won’t have to worry about being attacked by other monsters.
Just as before, your task will be to bring two cables closer.
Choose violet cables (screen).
A nearby elevator is now active and you should go there now.
Listen to a short conversation in the meantime.
Find a panel and press the first button to go up.
It would be a good idea to prepare for the next battle before the elevator reaches its destination.
Use the explosive bottle once again to acquire fire bullets.
Once you’ve arrived, destroy a glass wall and enter a large toilet.
Try moving forward and you’re going to be attacked by a new fissure monster.
Get rid of it the same way you’ve dealt with the previous creature (screen).
Try going to the next room.
Notice that you won’t be able to pass through until you’ve dealt with the fire.
You should be able to find a fire extinguisher here (screen).

Go back to the flames and use the extinguisher.
You may proceed to the next section.
Once you’ve reached a new area, you should receive a call from Sarah.
It looks like she’s in serious trouble, however you might’t help her right now.
Go to your right (screen).
Take at least one explosive bottle and choose it right away.
Pick a pistol for your other hand.
Start moving the other way.
A cut-scene is going to be displayed once you’re near the corner.
This is a warning, because you’ll have to deal with a new throw in of a monster.
Once you’ve regained full control over Carnby, take cover behind the left table (screen).
you might’t stay in the open, because the monster is capable of attacking you from a distance.
Try leaning out for a short while and throw an explosive bottle at the first monster (screen).
Obviously you will have to check that that the bottle will find its way to that location.
Try avoiding the projectiles at the same time.
Blow up the bottle at the last second (screen).
If you’re successful, you should kill the creature or at least seriously harm it.
Keep repeating these actions until you’ve killed at least one monster.
Use the fire extinguisher to put out the flames and deal with the second monster.
Once this is done, proceed to a new corridor.
Thankfully, you won’t encounter any other monsters along the way.
Eventually you’ll come across a closed door.
Pick up a larger object and use it to destroy this door (screen).
You could also try blowing the door up, however it won’t be necessary.
Either way, you will have to find your way inside.
Keep heading forward until you’ve reached a much larger area.
This is where the fourth chapter of the game will come to an end.
