Factories form the financial backbone of every match in FrontWars, an IO-style real-time strategy game developed by Phoenix and VexxusArts. Rather than relying solely on passive territorial income or small bot annexations, placing factories spawns trains that travel across rails to deliver goods to designated cities. Understanding how train payouts scale, where to position your factories relative to your cities, and how partner trading works will allow your economy to snowball into millions or even billions of gold.
How the FrontWars Factory and Train Economy Works
In FrontWars, factories generate gold through an automated rail transit system. Once placed, a factory automatically routes rail tracks to nearby cities and begins dispatching delivery trains.
Official Steam documentation confirms that trains carry goods between your urban centers and pay you gold upon every completed delivery. Player testing shows the baseline earnings per delivery:
- Factory transit: When a train simply rolls past or through a factory along its route, it awards an extra 25,000 gold.
- Base city arrival: Delivering goods to an unupgraded city awards a base payout of 50,000 gold per delivery.
- Transit scaling: If a single train route moves past intermediate factories into a city, the baseline payout combines (for example, rolling through a factory into a city yields 75,000 gold in a single trip).
Economic mode heavily influences speed. While Classic mode runs at a measured pace, Fast-paced mode accelerates economic generation and cash flow, letting you reach high-tier structures and weapon stockpiles significantly earlier.
Upgrading Factories vs. Upgrading Cities
Both factories and cities can be leveled up, but they serve two distinct mechanical roles in your empire's development:
- Factories control train volume and spawn frequency. Leveling a factory (up to level 10 or 12) increases the rate at which trains spawn onto the tracks. However, community testing highlights that upgrading a single factory past level 10 or 15 delivers diminishing returns due to internal train spawn cooldowns. Placing several level 10 factories on separate sides of a city generates far more consistent train flow than investing millions into a single mega-factory.
- Cities control payout multipliers and troop caps. Upgrading your cities directly boosts the delivery payout. A level 2 city raises single-train delivery value to 75,000 gold, a level 3 city pays 100,000 gold, and heavily stacked cities (such as level 50 to level 100+) award 1,000,000 gold to 2,000,000+ gold per train arrival. Additionally, high-level cities dramatically raise your maximum troop capacity, scaling your standing army from hundreds of thousands to millions.
| Structure | Primary Function | Gold Multiplier Scaling | Recommended Investment Level |
|---|---|---|---|
| Factory | Dispatches delivery trains across rails | Adds 25,000 gold when trains pass through | Level 2 to Level 10 (spread across multiple structures) |
| City | Receives trains, pays final delivery reward | Scales from 50k base up to 1M–7M+ gold at high levels | Level 10 early; push to Level 50–200+ once income stabilizes |
Optimal Factory Placement and Layout Patterns
The physical positioning of your factories relative to your urban centers determines train routing efficiency:
The Tight Cluster (Surround Strategy)
Place your main city first, then build factories in tight proximity on its borders (north, south, east, and west). By keeping the track distance short, trains complete journeys rapidly without wandering across foreign borders or pathfinding in inefficient loops.
The Linear Corridor
Line up factories and cities in a direct row along secure internal territory or against natural map borders (such as coastline or map edges). This design ensures that every train rolls through consecutive structures, picking up intermediate transit bonuses before hitting the terminal city.
Spacing Considerations
Do not scatter factories haphazardly across wide open plains early on. If factories are placed too far away, trains take longer to deliver payouts. Furthermore, if you expand your territory too rapidly, you risk drawing early aggression from rival players and bot nations before your defenses are operational.
Maximizing Profit Through Alliances and Partner Trading
Connecting your rail infrastructure to friendly players or bot nations dramatically escalates your gold production:
- Shared Rail Networks: Placing a factory that runs a train line into an allied player's city generates massive delivery bonuses. Player footage shows that delivery trains running between allied border cities can jump from standard six-figure payouts to 5,000,000 to 20,000,000 gold per delivery, benefiting both participants.
- Port Trading Alternative: Coastal ports function similarly to trade hubs, sending trade ships to allied ports for export income. However, player analysis confirms that terrestrial factories and cities are generally preferred for early-to-mid game scaling because ports cost more base gold (around 300,000 to 500,000 gold) and do not increase standing land troop maximums like cities do. Warships can be deployed from ports to defend sea routes or raid enemy trade lanes.
- Diplomatic Risk: Forming early alliances provides safety and trade income, but breaking an alliance incurs a severe penalty—the game applies an immediate 50% debuff upon betraying a partner.
Protecting Your Industrial Hubs
An unprotected industrial sector is an easy target for enemy strikes. Once your gold reaches stable six-figure generation, immediately fortify your core:
- Deploy Surface-to-Air Missile (SAM) Launchers: Build SAM launchers on the outer edges and directly beside your high-level factories. Unupgraded SAMs help intercept incoming hydrogen bombs and conventional air strikes.
- Level Up Central SAMs: Upgrading a SAM launcher situated directly adjacent to your primary city/factory hub to high levels (such as level 15 to level 30+) provides the heavy defense required to survive MIRVs (Multiple Independently Targetable Reentry Vehicles).
- Establish Secondary Hubs: Stacking all your infrastructure into a single tile creates a catastrophic single point of failure. Establish a second regional hub once your initial core is fortified, ensuring you maintain income even if one sector is wiped out by surprise nuclear bombardments.
Frequently Asked Questions
What is the default hotkey to build a factory in FrontWars?
In the desktop and browser interfaces, factories are bound to key 2 on your keyboard (with other buildings and units mapped across keys 1 through 8, such as key 6 for SAM launchers).
Can trains travel across nuked territory?
Yes. Delivery trains continue running across damaged, nuked territory along established track corridors, allowing surviving hubs to sustain income while you rebuild destroyed outer structures.
What happens if an ally breaks your trade alliance?
If an alliance expires or a player chooses to betray you, the shared trade routes stop yielding cooperative bonuses. The betraying party is struck with a temporary 50% debuff, giving you an opening to retaliate using missile silos or troop offensives.
