Flux Economy

Sanctuary: Shattered Sun replaces traditional RTS stockpiles with Flux — a streaming economy where income and expenditure happen in real time. There is no hard cap on how much energy or alloys you can hold in reserve; instead, your industrial base continuously produces resources while every factory, turret, and engineer drains them the moment work begins. Mastering Flux is the difference between a stable mid-game expansion and a sudden recession that stalls your entire war machine.

Unlike games where you save up 500 metal before clicking a tank, Flux rewards players who think in rates rather than balances. If your net Flux is positive, you can queue projects freely. If expenditure exceeds income, you enter deficit spending — and sustained overspend triggers recession, slowing production and leaving you vulnerable to a timing attack.

Real-Time Income and Expenditure

Every controlled extractor, refinery, and power node contributes to your Flux income stream. Income ticks continuously while the match runs; there is no batch deposit at the end of a mining cycle. On the other side of the ledger, expenditure is equally live: queued units consume alloys as they are fabricated, structures draw energy while they construct, and upgraded chassis bleed resources until the upgrade completes.

Watch the Flux panel for three numbers that matter:

• Gross income — total production from all active sources
• Gross expenditure — everything currently draining Flux
• Net Flux — income minus expenditure; the heartbeat of your economy

When net Flux is green, you are building wealth. When it turns red, you are eating into operational margin. The game does not stop you from queuing more work while in the red — that is intentional. Sanctuary wants you to feel the pressure of overcommitment.

No Hard Caps

Sanctuary deliberately avoids arbitrary storage ceilings. You will not hit a “silos full” wall that forces wasted mining. Instead, economic pressure comes from cash flow: if you cannot pay ongoing costs, things slow down or stall.

This design has strategic implications:

• Banking is less important than securing income nodes and keeping extractors alive under fire
• Turtle strategies still work, but only if your passive income exceeds your defensive upkeep
• Raiding enemy economy means destroying income sources, not emptying a single warehouse

Players coming from Supreme Commander or Total Annihilation should note that while the feel is similar, Flux is more punishing about simultaneous project overload.

Engineer Drain While Building

Engineers (and their faction equivalents) are the hidden cost center of Flux. When an engineer begins constructing a structure or assisting a factory, it continuously drains energy and alloys from your stream for the duration of the build. Multiple engineers on one project accelerate completion — but they also multiply drain.

Common mistakes in the Demo:

• Assigning six engineers to a forward outpost while your income is already negative
• Starting a superweapon foundation during a heavy unit production spike
• Forgetting that repair and reclaim tasks also tie up engineer bandwidth and Flux

The How to Manage Flux Economy guide walks through practical engineer budgeting. As a rule: never add engineers to a build unless your net Flux can absorb the extra drain for the full construction time.

Recession and Overspend

Recession is Flux’s penalty for sustained deficit. If your expenditure exceeds income for too long, global production efficiency drops: factories slow, upgrades stall, and power-dependent units may underperform. Recession is recoverable — unlike a checkmate — but the window gives aggressive opponents time to push.

Triggers that commonly cause recession:

• Mass unit queuing after losing extractors in a raid
• Simultaneous superweapon, expansion, and army rebuild
• Power node loss without rerouting energy infrastructure

Recovery means cutting expenditure before boosting income: pause lower-priority queues, cancel redundant construction, and retake or rebuild income nodes. The EDA faction tolerates brief deficits better thanks to industrial throughput, while Chosen players feel recession hardest because their units are expensive to replace.

Faction Notes

Faction	Flux Strength	Recession Risk
EDA	High volume production, efficient refineries	Low if you avoid over-queuing
Guard	Cheap drones offset engineer costs	Medium — swarm losses spike rebuild drain
Chosen	Elite units, strong late income with shields online	High — each loss is a Flux hole

See the Faction Tier List for meta context on which economy suits your playstyle.

Practical Tips

1. Pause queues before starting expensive structures — do not rely on cancel refunds alone
2. Scout income nodes early; Flux wars are won by map control
3. Stagger expansions so engineer drain peaks do not overlap
4. Reclaim wrecks (see Wreck Reclamation) to inject alloys during recovery
5. Pair with weather control — denying oceans or freezing passes protects extractors (see Weather Control)
