After passing through the gate, head left along the dirt path. Call over Sheva to open the exit door. Enter the house up ahead and collect the handgun ammo/gold in the wooden crates. Jump through window to the right and exit out the back door. Make a left past the broken ladder and kill the woman feasting on the dead corpse. Make a left down the road, and approach the broken ladder. Give Sheva a boost up to the platform above to collect the Old Building Key.
As you regroup with Sheva, get ready to fend off the three majini coming down from the roof above. Go through the right door making your way left down the alleyway. Kill the majini hiding behind the stack of boxes and continue right, around the corner into the house with the blue door.
Upon entering the house, grab the shotgun ammo on the shelf, and the gold in the back room. From the top of the staircase, make a left onto the balcony. Walk over to the railing and aim over to the south wall of the opposite building to find BSAA Emblem #01. Go back inside the building and grab the first aid spray sitting on the shelf. Kill the two majini hiding behind the stack of boxes and collect the Antique Clock inside the treasure chest on the left end of the balcony. Drop down the ledge and call over Sheva to open the door to the right.
Upon entering the next map, head over to the green house to the left, and open the door using the Old Building Key. Inside, grab the Ithaca M37 (SG) hanging from the wall. Head back outside and make your way up the stairs to the next house.
As the blonde woman approaches you, shoot her directly in the head with your shotgun. After a number of shots, her head will explode, causing a parasite to emerge from her body (One hand grenade should do the trick). Once you kill the blonde woman, be sure to collect the Ivory Relief she leaves behind. Exit through the back door to the right and head down the stairs. Run past the group of majini to the exit door at the south end of your map.
Upon entering the abandoned building, navigate through the hallways and head up the stairs. After climbing the ladder up to the second floor, direct your attention to the water tower above containing BSAA Emblem #02. Hop across the gap to the exit door. After paying your last respects to fallen Alpha Team soldier, Dechant, go through the back door, and head up the elevator.
From the main hallway, head left into the furnace room. Collect the Furnace Key near the body of the dead soldier. Leave the furnace room, and head back to the main hallway to trigger the Uroboros bossfight.
Run back to the furnace room and knock down the red gas tank posted up against the wall. Have the Uroboros absorb the gas tank and lure him inside the incinerator. Once inside the incinerator, shoot the gas tank to temporarily stun the Uroboros. Head back outside and pull the lever to the left. The incinerator doors will close leaving the Uroboros to a burning crisp.
Go back to the main hallway, and use the furnace key to unlock the door to the next room. Head straight down the hallway and collect the handgun ammo inside the metal case. Right before you enter the elevator, turn right towards the caged fence to find BSAA Emblem #03 latched to the wall. Ride up the elevator to end the chapter.
