Economy Fundamentals — Why You're Losing the Money Race

The Mindset Shift

OpenFront isn’t won by who conquers the most — it’s won by whose economy curve is steepest. If your opening reads “fight bot → take ground → fight bot”, the AI is quietly stacking Gold and you’ll see an Atom Bomb hit your capital around the 5-minute mark.

Switch your goal from expansion to infrastructure. The rest of this page is the build order, the math, and the traps.

Why “Holding the Enemy at 20% HP” Is a Loss

Frontal defense is net-negative without buildings:

Terrain mag is only 80/100/120 (Plains/Highland/Mountain)
A Defense Post multiplies mag ×5 and speed ×3 within 30 tiles
Without a Defense Post on your border, trading 18% to deal 20% means you both lost ground — the AI just refills faster because it isn’t paying for the loss

At 50,000 Gold, the Defense Post is the highest ROI building in the game. Drop 2-3 on your front line before anything else.

The AI Nuke Clock

Why someone “already” had nukes when you’d barely captured a Factory:

Base gold:      Player 100/tick, Bot 50/tick, Easy Nation × 0.5
Missile Silo:   1,000,000 Gold (100 ticks build)
Atom Bomb:      750,000 Gold (fixed)

An Easy AI hits 1.75M Gold in roughly 5-7 real minutes. 5 minutes is the deterrence deadline. Miss it and you’re eating bombs before you’ve broken ground on a SAM.

Standard Build Order (First 5 Minutes)

Time	Action	Cost	Why
0:00-1:00	Grab a small bot, sprint for coastline	—	Tiles compound your population cap
1:00-2:00	2-3 Defense Posts on border + 1 Port + 1 Factory	150k + 125k + 125k	Lock the front, start two trade streams
2:00-4:00	Upgrade City / Port / Factory to level 2	250k each	Each level doubles output
4:00-5:00	1 Missile Silo + 1 SAM	1M + 1.5M	Even with no Atom Bomb, the SAM alone is deterrence — bot nukes route around its 70-tile disc

Why Your Trade Ships Got Wiped

Three things compound:

Trade ships shuttle between Ports. With only one Port, they sail to other players’ Ports, including AI you’re not at war with.
Routes through hostile water = dead routes. Since v24, Warships prioritize Transport and Trade ships and cool down immediately on hit — a single hostile Warship between you and the destination Port kills the entire stream.
Inland Ports lose money. A Port buried in your interior forces ships to detour through more contested water.

Trade ship revenue:
floor( (75,000 / (1 + e^(-0.03 × (dist - 300))) + 50 × dist) × goldMultiplier )

Distance < 300 only earns the floor (~50 × dist). Long routes pay more but die more — that’s the tradeoff.

Train Economy: The Safer Money

In v24, single-player and private lobbies have Trains. Factories spawn them, they shuttle along rails between your Cities and Factories, and Warships cannot touch them.

Train revenue per delivery:
ally = 35,000  ·  team = 25,000  ·  self = 10,000
− 5,000 × max(0, citiesVisited − 9)
floor 5,000

Spawn rate: (factories + 10) × 15 ticks

Self-loops only pay 10k each, but you control 100% of the line. Three Factories looped through five Cities = an income stream no enemy can intercept.

Priority Cheat Sheet

Priority	Buy	Cost	Why
★★★	3-4 Defense Posts on the border	50k each	Mag ×5, the only way frontal defense breaks even
★★★	1 Port + 1 Factory in your core	125k each (n shared)	Two parallel income streams
★★	Upgrade Port / Factory / City to L2-L3	250k → 500k → 1M	Each level doubles output
★★	1 Missile Silo + 1 SAM by 5:00	1M + 1.5M	Bot nukes detour around SAMs — buying insurance
★	More Factories for train looping	up to 1M each	Income immune to Warships

Classic Mistakes

Building a second Port before a Factory. Port costs scale on n = ports + factories, so two Ports cost the same as a Port + Factory — but the Factory gives you Trains, which can’t be sunk.
Naked Port on a coastline tip. Pretty for trade routes, but the first Warship that sails by makes it a 125k loss. Build a Defense Post adjacent to coastal Ports.
Waiting for “enough Gold” before a SAM. The SAM is the prerequisite for building Gold safely. Bot nukes target unprotected core tiles.
Spamming Atom Bombs. At 750k each, a level 3 SAM swats the whole salvo. The real nuclear weapon is the Hydrogen Bomb (5M).

Decision Tree

Is your border held by ≥ 2 Defense Posts?
├─ No → Build them first. Nothing else matters.
└─ Yes → Do you have a Port AND a Factory?
    ├─ No → Build whichever is missing (125k)
    └─ Yes → Is it past 4:00?
        ├─ No → Upgrade buildings to L2
        └─ Yes → Have you placed a SAM?
            ├─ No → Silo + SAM immediately, even without an Atom Bomb
            └─ Yes → Stockpile to 5M Gold → Hydrogen Bomb

The One-Line Summary

Before minute 5, you are an economy game. After minute 5, you are a nuclear game. If you skip the first phase, you don’t get to play the second.
