Walkthrough

Underpass

"Even calling it a monster isn't quite right. This is something else. All I know is...something's in there."

Finding a Map

Descend the stairs and pass through the large door at the right end. Avoid the Numb Body and Pendulums in here and go through the blue door to the left, along the right wall a bit down.

Note on Extra New Game: The opening stairway and some additional hallways of the Underpass will appear all bloody and transformed in an Extra New Game. Staying in these hallways will drain your health on Hard Action Level, so proceed through them as quickly as you can. Don't bother healing until later as the effect cannot kill you and will only keep draining additional health.

Ignore the Numb Bodies in here (or just beat down the first one) and pass through the right door, since the hallway only loops around with nothing to find.

Up ahead three Numb Bodies will emerge from a short hallway. You can just wait for them to come out while standing back and then run where they came from and through the blue door.

Map Room

Here you'll find the Underpass Map on the left chalkboard. Right beside it is a new weapon called the 16 Maul stabbed into a bloody, fallen locker. It's a powerful weapon but somewhat difficult to use due to its slow speed. Also on the shelf on the other side might be a First-Aid Kit if somewhat low on health. Exit through the other blue door.

Southwest Corridor

Mind the large Numb Body and two smaller ones down the hall. Pass through the blue door on the right to a blocked hallway where you'll find an empty 17 Wine Bottle in a wine rack near some Beef Jerky. Back in the previous hall, continue around the right corner for Shotgun Shells on the corner barrel.

With more Numb Bodies around, head back the other way and take the right opening to and through the large end door.

South to North Passage

Head down the hall to be greeted by Pendulums. Carefully cross between the two by the blue door to move through it and say goodbye.

It looks like there's a metal pipe on the ground here but you can't pick it up. Continue through the door down the long hall to the north corridor. Take a right to head east and pass through the large door at the right end.

Eastern Corridor

Ignore the first right hallway for now as a large Numb Body approaches. Consider killing it along with another one that follows. Take the second hallway and enter the small room.

Get the Handgun Bullets and Shotgun Shells on the desk ahead. You'll find two Health Drinks on the right side and a Save Point on the north wall. Beside the save point is a kerosene heater. Use the Wine Bottle from your inventory to make it the 18 Oil-Filled Bottle. Exit the room and use the other hallway opening to access the northern small room, past a new flock of Numb Bodies.

In here you'll find ladder leading down but the area is filled with water. Find the machine with the open tank and use the Oil-Filled Bottle to fill it up with kerosene. Use the switch on the right side to drain the room below and head down the ladder.

Lower Level Sewer

Find the stairs and move up a couple flights to pass through the end door. Continue over the bridge and through the door down the long stairway.

Now in a sewer, take a right to head south. You may soon encounter a large Numb Body. Either beat it down or jump down into the water where it can't reach you to get past it. Climb back up if you need to and head through the blue door at the right end.

Garbage Room

Climb the steps and enter the room on the other side of the bridge (note the enemy corpse below as you do). Now in a garbage room, grab the hair 19 Dryer from the chair. There's also an Ampoule on the nearby shelf. Heather will point out some interesting trash items if you look around. Leave the room, and you may notice the enemy corpse is now missing from under the bridge... Head back east to the sewer.

Lower Level East

Move around and through the large white door here. Navigate past a large Numb Body and small ones to move through the blue door to the left. On the ground in this room is a Save Point. There's also a Health Drink on the desk and a memo about a sewer monster on the far side of the desk.

The memo serves as a warning for the next room, along with more scattered papers on the floor that according to Heather confirm the fate of the two mentioned. Note the fallen Danger sign and pass through the other door.

Bloody Walkway: Monster or Myth?

Out here you'll find a very bloody walkway so there must've been some truth to the previous document... Do not cross the walkway as is or you will die.

The author mentioned if only they had a hand grenade... But you do have something a little more creative. Find the outlet near the entry door and use the Dryer from your inventory. Heather will plug it in and toss the running hair dryer into the water to kill the monster. Now you can cross safely to the other side.

Escaping the Sewer

Leave through the bloody exit door. In another sewer, drop down and climb up the other side to make your way south along the right wall. Careful of the four Pendulums here, find the west opening and go through the door at the end.

Head down and up the stairs to pass through the other door. Make your way up the metal staircase and use the ladder to exit the underground passage.

Outside

Follow the path around the right corner to find a Save Point on a barrel. Then enter the building through the nearby double doors.
