The fastest way down is to stop mining
Every instinct in a mining game says dig out every vein you see. In SteamWorld Dig that instinct loses you the run.
In Archaea, the first area, you should ignore every deposit that is not directly on your path downward. The money there is not worth the time it takes to collect — and the trip back up to sell it costs more than the ore is worth. Get down, get out, move on.
The real money is at the bottom. Vectron pays roughly 900 per full bag, which is several times what Archaea yields. So the correct shape of a playthrough is:
- Fall through Archaea as fast as you can.
- Beeline through Old World to the drill.
- Get the Mineral Detector in Vectron first, then go back and clean the place out with everything visible on the map.
Do it in that order and money stops being a problem. Do it backwards and you will spend an hour turning $8 of Trashium into a pickaxe you will not use.
The three areas
| Area | What it is | What you get |
|---|---|---|
| Archaea | The first area, and the tutorial | The drill, and your basic tools |
| Old World | The middle area, where money starts to matter | The Steam Punch, dynamite, fall protection |
| Vectron | The last area, high-tech, cold and metallic. The domain of the Voltbot | Mineral Detector and Static Dash |
You enter Vectron by reaching the bottom of Old World, and the Fall Dampeners make that possible — though it can be done without them. The breakthrough happens at around 430 metres, and you fall into Vectron somewhere around 470 metres or deeper.
Vectron is where the game changes:
- Gravity-following blocks that can kill you instantly.
- Regenerating dirt that can seal your route back upward behind you.
- New enemies: Mecha Trilobites (tougher Trilobites), Laser Turrets, Laser Boxes, and Kamikaze Bots that charge and explode.
To climb a long vertical shaft of regenerating dirt, wall-jump continuously until the patch below you reappears, stand on it, punch straight up with the Steam Punch, and repeat. Do not treat it as a wall — treat it as a staircase that rebuilds behind you.
Worth knowing: Vectron has only two Teleporters, one at the halfway mark and one outside the final boss room. Plan around those, because you cannot drop one wherever you like as freely as you did above.
The upgrade order that matters
Pouch → Drill → Steam Punch → Water → Health.
The pouch is first for a reason that has nothing to do with combat: a bigger bag turns every single trip into more money, and it pays for everything after it.
And the counter-intuitive one: stop upgrading the pickaxe. Once you have the drill you will be drilling, not swinging, so further pickaxe upgrades are money spent on a tool you are not using. The same goes for the lantern — you should not be down the mine for more than a few minutes at a time.
Two habits that follow from this:
- Always carry a Teleporter. Skipping the pickaxe upgrades frees up the orbs for a dozen of them.
- Upgrade your current bottleneck, not the next tier. If hard soil is slowing every swing, the drill. If you are leaving minerals behind, the pouch. If darkness is cutting your trips short, the lantern.
One save-related rule to internalise before you lose an hour: the game only saves when you return to Tumbleton or buy something from a shop. Nothing you do in the mine is banked. If a run goes bad, pause and exit to the menu instead of dying in it.
Also useful: gaining a new ability refills health, water and light all at once, while buying an upgrade refills only that one type. If you are low on two of the three, going for the next cave is cheaper than buying.
The final boss: Voltbot
Voltbot is the only boss in the game, and it sits at the bottom of Vectron.
The method: destroy its generators to bring the shield down, then drill it. That takes three rounds, and each round changes Voltbot’s attack frequency and pattern.
The thing that makes it manageable is the Steam Punch: a fully charged punch destroys a generator in three hits. Have the Steam Punch maxed, and ideally with Hydraulic Fluid to shorten the charge time. Maxed health and damage reduction are not critical here.
Do not skip the generators and try to out-damage the shield. And do not forget that the final boss map has a hidden area of its own — it is the one people miss most often.
How long it takes
Two recorded runs, for calibration:
| Run | Finish time |
|---|---|
| Full clear including a sweep of every deposit and cave | 2h22m |
| Speedrun with the stops pulled out | 2h13m |
Inside the speedrun, the four-star targets of $20,000 and 150 orbs were hit at 2:09. The rough shape of a paced run is:
| Checkpoint | Target |
|---|---|
| First area cleared | 0:30 |
| Second area cleared | 0:45 |
| Third area, up to the boss door | 1:00 |
| Caves one and two swept for ore | 1:20 |
| Third area swept for ore | 2:00 |
| Final boss dead | 2:30 |
A sub-2h30m finish is the speedrun target, and it is achievable without sequence breaking if you are willing to skip the optional detours.
What happens to Rusty
Rusty is the bot you play, and the game does not end well for him. He descends into Vectron and goes missing, never to be found again.
That is the entire premise of the sequel. SteamWorld Dig 2 is Dorothy going down into the same world looking for him, and when she reaches Vectron she finds it in ruins. If you plan to play them in order, that disappearance is the hinge between the two — see the series order guide for where they sit.
