Refabrication and Cliff Crushing Guide

If your base is reaching the point where basic units, weak walls, and starter materials stop keeping up, Tungsten is the resource that decides whether you can push into late-game production or stall out. Start treating it like a progression choke point, not just another ore: get a reliable supply, protect it, and spend it where it unlocks more growth first. That means refabricators and production upgrades come before luxury defenses, and defenses come before anything decorative.

Decide what Tungsten should go to first

Tungsten is one of the few materials that can immediately change what your base is capable of doing. You will use it in the Mech Refabricator, Ship Refabricator, and Tank Refabricator, and it also goes into advanced structures like Surge Conveyor, Surge Router, Reinforced Container, Reinforced Vault, and core buildings such as Core: Citadel and Core: Acropolis. On the defensive side, it is required for heavy parts like Tungsten Wall, Large Tungsten Wall, Blast Door, and Reinforced Surge Wall variants.

The right move is to treat Tungsten as a progression resource first and a building material second. If your supply is limited, put it into the structures that unlock more production and more unit options before you sink it into broad defensive upgrades. That way, every piece of Tungsten helps you generate more throughput or combat capability. If you spend too much too early on walls, you can end up protecting a base that never actually grows.

Once you have a functioning refabrication line, then start widening into logistics and fortifications. Until then, every nonessential Tungsten sink is slowing the part of your base that actually creates momentum.

Set up a Tungsten mine that actually works

Tungsten has hardness 5, which is what makes it awkward compared to earlier ores. On Serpulo, the Airblast Drill is the only drill that can mine it, and it yields less per tile than Thorium. The Impact Drill has enough drilling power to break Tungsten in mechanical terms, but it is intentionally prevented from mining it.

That means you should not build your Tungsten economy around the wrong drill tier. Go straight for Airblast Drills, and build your mine around the fact that output will be tighter than you are used to. Do not expect the same casual throughput you may have gotten from easier ore fields. Instead, make the mine secure, compact, and easy to feed.

The practical play is simple: choose a Tungsten patch you can defend, set your mining footprint deliberately, and keep transport short. If you try to stretch an underdefended Tungsten operation too far, you are just creating a weak point that slows every advanced project in your base.

Protect the mine and move the ore like it matters

Tungsten is a strategic bottleneck for many late-game builds, so assume your source will become a target or a weak point. Your mine should not be an exposed side project; it should be a defended outpost. Wall it off, cover the approach, and keep the route back to your main base as clean as possible.

For transport, start with conveyors if the path is simple and safe. Upgrade to Surge Conveyor and Surge Router only when the extra throughput or reduced congestion is actually helping you. If the route is long, vulnerable, or awkward, payload systems are worth considering because they can be easier to protect than a wide exposed belt line.

Do not overbuild transport just because Tungsten is important. The goal is not maximum glamour; it is reliability. A short, protected line that never chokes is better than a flashy route that gets broken or starves your refabricators under pressure.

Feed your refabricators without starving the rest of the base

The Mech Refabricator, Ship Refabricator, and Tank Refabricator all compete for the same Tungsten pool that your defenses and logistics also want. If you let everything share one undifferentiated supply, your unit production will collapse the moment you start expanding or take heavier losses.

What you want instead is a dedicated Tungsten stream for unit production. Reserve enough to keep your refabricators running, and do not keep pulling from that line whenever you want to place another wall or replace a random structure. If your army production stalls, your base stops being able to push, defend, or react. That is usually the point where a stable economy starts losing ground.

Use Tungsten for unit production during major offensives, not only for peacetime buildup. The whole point of refabricators is to turn your resource advantage into battlefield pressure. If you are sitting on a pile of Tungsten while your frontline is under-strength, you are wasting the material’s best role.

Scale into advanced industry only after your supply is stable

Once your refabrication core is running, then you can widen into Tungsten-heavy industry. Tungsten is tied to advanced production buildings such as Carbide Crucible, Surge Crucible, Synthesizer, Electric Heater, Heat Redirector, and Slag Incinerator. It is also used for reinforced storage, pumps, ducts, conveyors, routers, and payload logistics buildings.

The key is to expand in layers. First, lock in the refabricators. Then add the logistics and storage that stop the line from clogging. After that, bring in the advanced material chain that benefits from a stable Tungsten base. If you try to build every Tungsten-consuming branch at once, you will dilute your supply and end up with several half-finished systems instead of one strong one.

Also avoid wasting Tungsten on low-utility decorations or nonessential upgrades. Tungsten is too valuable to disappear into anything that does not either increase throughput, improve durability at a critical point, or unlock a stronger production chain. If a build does not move you toward more units, more material flow, or a safer core, it can wait.

The cleanest way to think about Tungsten is this: mine it safely, reserve it for progression, feed refabricators first, then expand into advanced industry. Do that in order, and Tungsten stops being a bottleneck and starts being the material that carries your base into the late game.
