Kill the Closer inside if you want,

Kill the Closer inside if you want, then exit
through the double doors. Here, you'll fight a new type of monster. It's
called the Pendulum. It can fly, does some nice damage, and has high stamina.
Avoid it if you want. There are also some Double-heads here. From the double
doors, head left, then right. On the north-west part of this area are a pair
of double doors that you can open. When inside, find the vise lying on one of
the beds. Use your walnut on it to receive a MOONSTONE. Exit the way you
came, go right, and unlock the door at the end of the walkway.

You're back in the central area. Head back to the escalators, be warned
because there are some new monsters hanging around, including a Pendulum.
Head up to the third floor, and use the moonstone on the locked door
opposite of the escalators. Go around the pit, and then down the ladder.
Get ready for a boss fight!

Difficulty - Easy

You climb down to a closed of area. As you walk away from the ladder, it
falls down. No way out. And to make matters worse, you're attacked by a giant
purple snake. It can come out of 6 holes, 3 on either side of the room. It
can travel to any hole from his current location, so don't think that when
he exits on one side he'll also come out on that side. When it comes out, it
opens it's mouth, screams a bit, and then either crosses the room or
retreats. It only attacks are stomping on the ground (doesn't hurt you, just
stuns you for a second) andattacking you with the head (will take your
health down to almost zero). Stay away from the head if you can. When the
snake comes out of a hole, stand on the other side, facing its head right
on. When it opens it mouth, fire 3 bullets into his head. No more, because
after 3 it will close. After that, retreat to a corner, and wait for it to
disappear. As long as you stay the hell away from its head, you're good to
go. It took me in normal mode exactly 14 bullets to kill it.
