Entering the Void 0 / 0

💡 Must-dos

Pick up the Journal floating ahead of the trolley (press J) — it starts quest tracking and your lore collection. Beginning Unlock & equip the Grappling Hook (Catcher quest, Tech Stage 10) — your main tool for pulling in scrap, wood, and fish. Grappling Hook Recruit your first Rofleemo and build it a bed (the Creature quest at the 6th Depot hands you one). Rofleemo Don't burn resources trying to kill the Void Shark — one or two hits scares it off, and it respawns every cycle anyway. Shark

Quest beats

Beginning

Pick up and open the Journal floating in the Void. Take the trolley off the brake, set the transmission lever, and pump the handle to accelerate.

Stop · 1st Depot

Sneak into the building; take the Revolver and the blueprints from the desk. Open the (already-unlocked) safe and grab the Parts; break the planks behind the skeleton to get out. Use the Building Console to expand your trolley, then leave the depot.

Others · between 1st–2nd Depot

Draw the soldiers' attention (sound the horn or fire the revolver) so they leave and unblock you. At the depot, fight off the enemies, then tune the radio and listen to the message.

Monster

Scare off the Void Shark with a hit or two (skippable — it returns each cycle). Shark

The Way · between 3rd–4th Depot

Clear the outpost, follow the power cable to the battery, and unplug (or shoot) it to drop the roadblock. Grab the wanted-poster leaflet before you leave (wait for the narrator to highlight it).

Breaking in

Push through the broken-in route to the next depot.

Creature · 6th Depot

In the lab, grab the documents, then free the Rofleemo sealed in amber and carry it to the Unpacker. Unpack it, build a Rofleemo's Bed (any wagon except the locomotive), and invite it aboard.

Secrets · 8th Depot

Sneak into the workshop and eavesdrop on the radio. Find the parts in the floor piles and build the Winch at the workbench, then leave.

The Island · between 8th–9th Depot

Follow the fireflies; take the Throwing Rings the ghost Rofleemo gives you (craft more at any workbench). Solve a Witch Island puzzle, have a Rofleemo teleport the Strange Chest to the train, then open it on the depot Altar.

The Trial

Touch the teleport-bird creatures to reach the Arena Master; fight the Swarm (up to 5 rounds — win or lose ends it) and take your reward.

Prediction · 10th Depot

Read the note on the broken Fortune Teller; find the Artifact + note in the workshop and set the pedestal on the front of your train. Follow the cable, fix the transformer fuse box, switch the machine on, and collect your Prophecy. Leave the depot with or without the Prophecy installed (installing alters your next cycle). Prophecy

Darkness · 12th Depot

Enter the lone building; find the 4 missing totems around the room to open the rune-sealed door. Examine the desk documents, the blackboard, and the altar; touch the altar totem, then run back to the train (you'll be teleported if you're too slow). Defend the train from the Deep Void Fish until you reach the Void.

The Chase

On a later cycle, finish the Chase event — break away or fight back.

Consequences · 14th Depot

At the ruined depot, follow the markers through the enemy area, climb to the platform, and use the collar mechanism, then leave.

Critical side content

Visit a Witch Island for a Strange Chest — reach it with your Winch + Throwing Rings along the Hook-Flower/firefly trail, and solve a Beam, Rune, or Combination puzzle. Witch IslandOptional Sweep every depot for glowing Scientist journals — they don't respawn and carry across Cycles, so grab them when you see them.Optional Install a Prophecy from a Fortune Teller to alter your next cycle for better odds/loot. ProphecyOptional

🤝 Co-op tips

One of you pilots and repairs (a hammer hit restores ~40% durability) while the other grapples scrap, wood, and fish. Split depot sweeps so nothing gets missed. In the Secrets quest, once one player triggers the workbench cutscene the Winch unlocks for everyone in the session — so only one of you needs to do it.

✓ What you should have by now

Research Table, Smelter I, Workbench I, Container I, Lab I, Water Condenser, Kitchen I, Revolver. Grappling Hook + Small Backpack (Stage 10), Winch, Throwing Rings. First Rofleemo aboard, and a Lootcatcher's Nest running (Stage 5).

▸ Chapter 2
Awakening 0 / 0

💡 Must-dos

Build the Steam Engine (Stage 12): expand the locomotive to 4 platforms, stock 4× Iron Ingot / Gear / Forcer / Copper Pipe / Bolts, build it at the Building Console, and fuel it with a Steam Battery. Steam Engine Keep collecting Scientist journals — Chapter 2 notes appear randomly in depots, so sweep each one. Keep your Winch + Throwing Rings stocked — most of this chapter's detours are reached by latching Hook Flowers. Witch Island

Quest beats

Outpost · between 14th–15th Depot

Shoot the infection bubbles to clear your path (one is only visible from a side window), grab the papers, and listen to the radio.

Awakening · 15th Depot

Investigate the roar; free the captured creature from its collar or just leave (the choice has no story effect).

Incident

Complete the Incident beat — it hands you the key you'll use at the Archive.

Archive · 16th Depot

Use the keypad (key from Incident) to enter; follow the ghost Rofleemo, play the recorder, and use the stone tablet. Find the legend documents and the ancient scroll; show the scroll to the sleeping Rofleemo for an amulet, then use the tablet again.

Meeting · between 16th–17th Depot

Winch across the Hook Flowers to the tower; use the tablet (with the amulet) to clear the fog along the way. Climb the tower to the altar at the top and place the amulet.

Clues · 17th Depot

Enter the building and take the documents from the second floor.

The First Prophecy · 18th Depot

Enter the building and examine/collect the first prophecy from the table.

Search · 19th Depot

In the museum, find the missing projector reel, follow the cable into the dark room and repair it (break the crates in the way), then run the projector slides.

Lighthouse · between 19th–20th Depot

Winch the Hook Flowers to the lighthouse, shoot the infection bubbles up each floor, and fix the mechanism at the top. At the island, solve the vortex puzzle — shoot the shields matching the tablet symbols, top to bottom — and take the prophecy.

Ghost · between 20th–21st Depot

Enter the outpost and play the recorder; listen to the rest or leave (no story effect).

Consolation · 21st Depot

Pick up the toy by the entrance, reach the top floor, and interact with the Ghost.

Memory · between 21st–22nd Depot

On Memory Island, inspect the arch and pedestals, follow the Ghost to the top, and take the last prophecy figure.

Decoding · 22nd Depot

Enter the building and lay out all three prophecies on the table.

Prophecy · between 22nd–23rd Depot

Winch to the altar, bring the amulet to the tablet, and place the prophecies in the clearing. Survive the afterburner rush back to the depot (dodge the laser beams), then check on the Ghost.

Situation

At the broken train on the rails, enter the right-hand wagon toward the rift, then start your train to finish.

Critical side content

Run 2–3 Lootcatchers for passive scrap/wood/fuel while you explore. Lootcatcher's NestOptional Build a Trainkeeper's Station (Stage 21) to auto-water your Lootcatchers. Trainkeeper's StationOptional

🤝 Co-op tips

The Lighthouse and island detours are smoother as a pair: one defends the parked train from boarders and mines while the other explores and grabs lore. When a Hook-Flower trail or Witch Island appears, one winches across while the other watches the rails.

✓ What you should have by now

Steam Engine running, locomotive expanded, several Water Condensers. Winch + Throwing Rings, 2–3 Lootcatchers, multiple Rofleemos assigned, and an Armory (Stage 8) for modular weapons.

▸ Chapter 3
The Threshold 0 / 0

💡 Must-dos

Fully clear Phase 3 research (especially the Lab 1 + Chemical techs) — it's the gate to Tier 4 / the Tesla Era. Research In Tier 4, prioritise Container Rack 1 (alongside Basic Components 2), then redesign your train storage. Collect the Chapter 3 journals — these are in fixed story locations tied to the Darkness objective, so don't skip rooms. Darkness

Quest beats

Chaos · 25th Depot

Sneak into the research complex; examine the creature exhibits and their tablets, inspect the vial, find the real specimen upstairs, then leave (vent shortcut or fight out).

Investigation · 26th Depot

Get onto the building's roof to enter; examine the blackboard and take the documents.

Dwergs' Depot

At the Forge, activate it, then pull the levers in the same order as the symbols shown to forge a weapon. Step outside and clear the enemy wave to test the weapon, then leave.

Premonition · between 26th–27th Depot

Let the ghost Rofleemo teleport you to the hidden spot; take the trinket from the pedestal.

Bait · 27th Depot

Find the parts (one pile is behind a door you open via the vent), assemble the bait at the table, then set the prophecies on your train's pedestal.

Breakthrough · after the 27th Depot

Ride the auto-driven cycle, deploy the bait at the marker, and push toward the hall.

Throne Hall · 28th Depot

Reach the arena and inspect the glowing sphere to trigger the final encounter. Clearing it ends the main story and rolls into the Epilogue.

Go in loaded: bring your best modular weapon, spare ammo/modules, and top up the train's repairs and defenses first — there's no restock mid-fight.

🤝 Co-op tips

By now your train is a small factory — centralise crafting and storage so both of you (and your Rofleemos) can reach it. Split roles for the final stretch: one runs miners/automation and repairs, the other handles combat and lore sweeps so no fixed journal gets left behind.

✓ What you should have by now

Phase 3 cleared, Tier 4 unlocked, Container Rack 1 built, storage reorganised. Solid defenses (turrets, armored walls) and modular weapons from an Armory for the final beats.

▸ Epilogue
The Tesla Era 0 / 0

💡 Must-dos

Finish Phase 3 research before expecting the Tesla Era — the electricity-based power tier only opens once Phase 3 is fully cleared.

Quest beats

Epilogue · The Engineer's Journey

Play out the Epilogue to the close of the Engineer's journey — the 1.0 finale that concludes the main story. Quests

The Epilogue is short by design. The Tesla Era is post-story sandbox content — a new electricity-based power system for continued building after the credits, not another story chapter.

✓ The end of the line

Main story complete, credits seen, Tesla Era unlocked for endless-mode building. 🚂
