Being stuck is an equipment problem, not a navigation problem
The single most useful thing to know about SteamWorld Dig 2 is this: if you cannot get somewhere, you are not lost. You are missing a tool.
The game builds its world out of walls that each have exactly one answer. A brick block needs the Jackhammer. A block you cannot reach by jumping needs the Pressure Bomb. A ceiling you cannot scale needs the Hookshot, and later the Jetpack. Players lose hours walking in circles trying to find another way around, when the way through was a purchase at El Machino.
So when you hit a wall, do not re-read the map. Ask which tool you have not upgraded.
The tools, and where each one comes from
| Tool | Where you get it | What it opens |
|---|---|---|
| Pickaxe | Starting tool | Dirt and basic rock, and melee |
| Pressure Bomb | A cave in Archaea — enter the large contraption at the bottom of a long descent | Any block you cannot reach by jumping. The master key of the game |
| Hookshot | From Rosie, in the Oasis | Ceilings, walls and grapple points; vertical shafts |
| Jackhammer | Progression | Brick and reinforced rock the Pickaxe cannot penetrate |
| Jetpack | Deep in the ruins | Sustained flight and the high platforms in the late biomes |
| Long Range Grappler | Ronald’s Treasure Chamber | A much longer Hookshot reach |
| Pneumatic Saw | Late game | Rapid horizontal clearing |
| Ignition Axe | Combuster’s Station Cave | Fire damage — and it moves the golem that guards Demon’s Crib |
One note on the Pressure Bomb: sources disagree. The GameFAQs walkthrough places it in an Archaea cave, while the Shapes.inc wiki says it is acquired in the Yarrow Caves. If it did not drop where you expected, keep progressing — you will get it from one of the two.
The route, in 17 steps
- Tutorial — pre-objective.
- Get to El Machino / Talk to the Mayor.
- Mine for resources, sell them, fix the lamp.
- Enter Archaea / Fix the Pneumatic Tube.
- Talk to the Mayor / Find the Mining Station.
- Talk to the Mayor / Enter Shiner Country.
- Talk to Rosie / Enter the Mining Station.
- Find a Smart Bot / Enter the East Temple.
- Confront the Prophet.
- Disable the Device / Talk to Rosie.
- Explore Vectron.
- Return to the Oasis.
- Unlock the Long Range Grappler.
- Destroy the Device — West Temple.
- Destroy the Device — Yarrow.
- Destroy the Device — East Temple.
- Confront Rosie.
Step 13 is the pivot. Everything before it is about reaching Vectron and coming back; everything after it is the three devices, and you are not meant to finish those before the Long Range Grappler is in your hands.
The Pressure Bomb cave, step by step
This is the one place players reliably stall, and it is worth spelling out.
Inside a cave in Archaea, head left and kill the beetle, then break the sand block in your path. Drop down and kill another beetle below. Work your way down slowly and avoid the cacti on the edges. If a beetle charges you, jump over it and let it drop into the water and drown — it is the cheapest kill in the game.
At the bottom of that path, stand on the red clay block on the right. It crumbles under you and drops you into a large contraption. Enter it to unlock the Pressure Bomb.
Two things to know immediately after:
- You will see two small blue bars below your health — those are your Pressure Bomb charges. Standing in water refills them, which is the entire resource management of the tool. There is no consumable to buy.
- The Pressure Bomb is the only way to break blocks you cannot reach. From this point on, any secret with a sand block in the ceiling is a bomb target, not a jump target.
Vectron is different, and it is meant to be
When the route takes you into Vectron, it stops being a mining game and becomes a stealth section.
Vectron is the ruins of an ancient robotic hive mind, and its security is an alarm. Floating Vectron Sprites detect you and trigger it, and once it is up, hulking Alarm Giants chase you. You cannot kill them with standard weapons — you have to outrun them, hide in water or on high ground, and wait for them to power down.
There are at least two places in Vectron where the alarm is scripted and unavoidable, so do not treat it as a failure when it fires. The Solid Sneak achievement asks you to finish the area having triggered it no more than twice.
This is also where you get your last two tools: the Mineral Detector and Static Dash, from the two caves there.
Cogs are free to move
Cogs are the game’s skill system, and they replace the linear stat growth of the first game. They are hidden in secret alcoves and rewarded by Challenge Caves, and you slot them into your equipment at any workbench in El Machino.
The important part: cogs can be removed and reallocated at any time, with no penalty. There is no wrong build to recover from. Slot for the job in front of you — ore-farming cogs for a sweep, boss cogs for a fight — and move them when the job changes.
What to do alongside the route
The main route will not 100% the map, and it is not meant to. Once you hit the point where the route opens up, the secrets sweep is a separate job — and it has a hard prerequisite.
Several secrets sit behind cracked blocks in the ceiling that your pick will not touch. The answer is the Sky Assailant mod for the Pressure Bomb, which lets you shoot bombs mid-air. Getting it costs a level 4 Pressure Bomb (level 14), 1,400 gold, and 3 cogs.
Buy it before you start backtracking, not after. See every artifact and secret, area by area for the full list.
