Below is a walkthrough for the New Dam City Chapter 3 quest in Eastward.
Tie in with Sammy and Jasper
Speak with Sammy and Jasper on the train to trigger a dialog event.
Explore New Dam City
Exit the train station and head south to reach Uptown. Keep heading south passing through the Buddha Fan arriving on Princess Avenue. Speak with Mr. Board who can be found standing on a stool near two other people for a dialog event.
Head to Alva’s Lab at the Rocket Mansion
Head east of Mr. Board then go north past the kid near the shutter (if you want to experience a ghost story, interact with the statue in front of the fan to the right of the northern path). Enter Rocket Mansion and head up the stairs. Interact with the door to trigger a dialog event. Head up the second set of stairs then proceed through the door to arrive at Alva’s Lab. Walk up the stairs, climb the ladder then head through the door to trigger another dialog event. Use the stairs at the back of the room to reach a workbench with a wrench sitting it. Grab it and bring it to Alva. This leads to yet another dialog event where you’ll be given a code name and Lab Assistant Badge.
Retrieve a slime-breeding furnace from Oldtown.
Exit Rocket Mansion then head to Princess Avenue. Take the stairs south of Mr. Board to reach Midtown then keep head south towards Oldtown. One of the shops in Midtown has three kids playing Earth Born. If you speak with them, a dialog event will trigger. When you near Oldtown, you’ll notice a commotion going in the middle of the street. Head east down the road and speak with the group to trigger a dialog event.
Clear the monsters out of the station
Head south to reach the City Outskirts and follow the pat east passing a pond. Keep going east to reach the next area then take the path north to enter another area. Head past the first fence then take a right. After defeating the spikey enemies there, move east a little bit to see some cracked stone pillars blocking off a set of stairs south of you. Drop a bomb then head down the stairs (be prepared to fight!). When you head far enough into the cave, the way out will be sealed and two hostile cows show up who like to teleport around the cave shooting milk at you. Dodge the milk and take the hits you can get. A good way to deal some damage is to stun them with Sam then hit them with John’s frying pan. After you defeat the two cows, head up the stairs to find a chest with a Heart Orb. Exit the cave then keep traveling east. In the next area, you’ll run into a big flying bug that summons little bugs. Continue eastward eventually you’ll follow the river south past a duck shooting duck grenades. If you take the southern exit, you’ll find a chest with 3 fish. Take the eastern exit to press on. Work your way north using the raft to cross the river. When you reach the stone steps guarded by two statues, you can follow the past east to reach a camp where you can save and heal up. When you’re ready, head up the stone steps to arrive at The “Big” Station. Defeat the two bird enemies here to trigger a dialog event.
Head to Oldtown in search of a Slime-Breeding furnace
Head north through The “Big” Station to reach the City Outskirts. Head west following the path through a dark forest to reach Oldtown. Follow the path north using Sam’s ability to clear the miasma. If you clear the miasma from the building with all the creates, you can find a chest with a gear part there. Be mindful that the miasma comes back after a bit. Head into the building north of you following the zombie the head north through the room to reach the back alley. Follow the way west using Sam to clear the miasma. In the next area, follow the sidewalk east and enter the last house at the end of the block.
In this room, there is a giant wooden crate on the left and right sides of the room. Move the left one up as far as you can then do the same to the right one. Now use the top path to reach the other side of the left crate and push it south blocking the entrance. Finally, pull the right crate down a little bit, then head through the northern doorway bringing you to another alleyway. Here you’ll need to use your gun and bombs to break the glass orbs. Doing so will destroy the plants blocking your way. Follow the alleyway and enter the building at the end. Inside use Sam to reach the right side of the room, then destroy the orb with John. This will clear out the plants allowing you to access the closest containing a key. Exit the building by heading south then head east. The next area will have a locked door. Use the Key to open it then head through and follow the path. You’ll enter an alley that will lock behind you. Defeat the crows then head through the southern doorway to arrive at Grandpop’s House. Save at the fridge if you wish then grab the slime-breeding furnace from the table to trigger a dialog event.
Use the Scepter of Flame aka the flamethrower to burn the plants blocking the building then head through the doorway. Place a bomb near the explosive barrels in the left room to blast out the wall and head through. Go north past the chainlink fence and use your flamethrower to burn the plants blocking the door on the left the head through it. Keep moving forward then take a left before the doorway towards the spikey flowers. Use the flamethrower to clear the way and follow it to enter a room with a chest containing a Friends of Johnny card. Return to the doorway and head through it. Work your way through the house then head through the doorway in the top right. Place Sam on the platform in the middle room then move John to the platform in the left room. This will allow Sam to enter the right room containing a chest with an advanced gear part. Return to the previous room and exit the home through the door due south.
Follow the alley east looting the chest with 3 tomatoes along the way. Keep heading forward and you’ll eventually pass a road with a zombie and a couple of venus fly traps. Just after crossing the bridge south of this road, take the southwestern path to reach a chest with a Heart Orb guarded by three zombies. Then take the path leading east crossing another bridge and use the flamethrower to burn the vines off the door. Head through then break all of the orbs to prevent the flowers from growing back. When you reach the room with a floor switch, move the nearby pillar onto the switch then head through the southern doorway to reach the Bramble Garden.
Send Sam through the tunnel then use John to clear the bramble and Sam to clear the miasma. Step on the switch southeast of where you exited the tunnel to open the fence for John to pass through. This will lead you back to Old Town. Follow the path with John bringing him near the vending machine, then shoot the bramble on the other side of the fence with the flamethrower. Switch to Sam and flip the newly accessible switch to open the gate. Stock up on any healing items from the machine then enter the building to find a save point. Save the game and head down the stairs when you’re ready to enter the Human Factory. Head south through two areas then take the northwestern tunnel. Approach the green monitor on the western side of the room to trigger a dialog event. Return to the previous room to start a boss fight with one of the machines. It drops bombs and shoots bullets at you so dodge and counterattack accordingly. When it’s defeated, use the northeastern tunnel to reach the next area then head through the western tunnel. Now head through the door here and follow the walkway west to once again reach Grandpop’s House. Approach the building to trigger a dialog event then you can finally take the slime-breeding furnace!
Report back to Alva
Backtrack to The “Big” Station. When you exit Oldtown, use the flamethrower on the bramble in the ruined structure south of you to find a chest with a gear part. When you get close to the station a dialog event triggers transporting you back to New Dam City where you’ll receive a Subway Pass. Make your way to Alva’s Lab in Rocket Mansion to trigger a cutscene. When you gain control of John, head into the kitchen and help Sam with dinner.
