Start With Decisions, Not a Script

A strong openfront build order matters because a fast purchase can still weaken your position if it leaves your army thin, your borders exposed, or your gold tied up in the wrong job. The best opening is not a fixed sequence of buttons. It is a repeatable decision process that responds to your nearest danger and most urgent limitation.

OpenFront has separate balances that can be easy to confuse. Gold pays for buildings, upgrades, ships, and nuclear capability. Troops pay for expansion and combat, while maximum troops is only your storage capacity, not your current fighting strength. Territory creates space and borders, and contributes a sublinear part of troop capacity.

That means an affordable building is not automatically the right building. A City does not solve an immediate problem when current troops are far below the existing cap. A Port is not useful simply because you can buy it if no safe foreign destination can complete voyages. More land can be a liability if it creates borders that cost more to defend than the land is worth.

Use this guide as a practical opening framework: expand carefully, identify the current constraint, make one purposeful purchase, then test whether it improved the position.

Build a Compact Opening Position

Your opening goal is controlled momentum. Start in a compact area with room to expand, one useful coast when possible, and few exposed directions. Claim nearby neutral land before competing for distant prizes, because neutral land is usually an opening resource while enemy land creates a political and military commitment.

Do not measure early success by the size of your color on the map. Measure it by whether the new territory leaves you with a usable troop reserve and a border you can still understand.

A useful early loop is:

  • Expand into nearby neutral territory.
  • Pause to read troop availability, gold, and border shape.
  • Keep enough troops at home to make attacks expensive.
  • Identify the main danger: a neighbor, a narrowing neutral strip, or a new coastal route.
  • Expand again only when the new border remains worth defending.

The key stopping rule is simple: stop growing when the next expansion would make your border harder to defend than the new land is worth. This avoids the common failure of creating several thin fronts that cannot support one another.

| Opening signal | What it means | Practical response | |---|---|---| | Nearby neutral land | Growth is available without committing to war | Claim it while keeping the position compact | | Narrowing neutral strip | Another player may soon compete for the same space | Reassess borders and keep a troop reserve | | Quiet neighbor | The threat may not be immediate, but can change | Watch the border rather than assuming safety | | New coastal route | Trade or naval access may become relevant | Consider a Port only if a safe route can complete | | Several exposed directions | New territory may be weakening the shape | Pause expansion and stabilize |

A compact position does not mean refusing all expansion. It means converting empty space into a stable economy before spreading into territory that creates more obligations than options.

Use LIMIT for Each Major Allocation

Instead of copying a strict opening, use LIMIT before every meaningful purchase or large attack:

| LIMIT step | Question to ask | Result | |---|---|---| | Lock | What is the nearest way this position can fail? | Protect against the most credible loss first | | Identify | Which resource is limiting me now? | Separate gold, current troops, troop capacity, and territory | | Measure | What route or combat job will this purchase perform? | Give the investment a specific purpose | | Invest | What is one reversible increment? | Buy or commit only enough to test the idea | | Terminate | What signal means this branch should stop? | Avoid adding more spending to a failing plan |

This framework produces different correct orders from the same start. One player may need a Defense Post, then a City, then a Port, followed by a reserve. Another may need a City, Factory, defense, and then expansion. The difference is the map, border pressure, troop level, and whether the economic route is actually usable.

Plan one purchase ahead rather than several purchases ahead. Attach a test to every branch. If the test fails, stop the branch instead of defending the original idea with more gold.

For example, a City test is whether current troops repeatedly approach the old cap and then use the added headroom. A Port test is whether an eligible route completes enough safe arrivals. A Factory test is whether its connected City or Port stations actually settle Train Gold. A Defense Post test is whether its zone covers the expensive approach.

This method also protects your liquid reaction money. The next 250,000 gold cannot simultaneously become City capacity, another trade engine, several first-price Defense Posts, and a reserve for an unexpected border problem. Choosing one means declining the others for now.

Choose Buildings by Their Job

Buildings are placed on individual map tiles and cost gold. They take a few seconds to construct and show a progress bar unless the lobby uses the Instant Build setting. You can open the radial menu by right-clicking a tile or long-pressing on mobile.

At the current v0.34.3 boundary described in the source material, Cities add 250,000 maximum troops. City prices follow their own exponential ladder. Ports and Factories use the same price sequence, but they share one counter with each other. Defense Posts have their own separate ladder.

| Building | Main opening job | Price progression | |---|---|---| | City | Adds 250,000 maximum troops | 125,000; 250,000; 500,000; then 1,000,000 | | Port | Supports trade ships and route-based trade | Shares Factory pricing: 125,000; 250,000; 500,000; then 1,000,000 | | Factory | Supports connected City or Port stations that settle Train Gold | Shares Port pricing | | Defense Post | Covers an approach with a 30-tile zone | 50,000; 100,000; 150,000; 200,000; then 250,000 |

A City is a capacity purchase, not an instant army purchase. Prioritize it when current troops repeatedly reach the old maximum and can use additional headroom. If current troops are well below the cap, another City may be a delayed benefit while your immediate problem remains defense, expansion, or route access.

A Port should have a real route job. The source material warns against buying one merely because it is affordable: it needs a safe foreign destination that can complete voyages. Ports spawn trade ships, and trade ships can be stolen, so route safety is part of the investment decision.

A Factory needs connected City or Port stations that actually settle Train Gold. Do not treat it as automatic income without checking that its connected network performs the intended job.

A Defense Post is strongest when its 30-tile zone covers the expensive approach. Place it to defend a meaningful border problem, not simply because it is the cheapest available building.

Commit Troops Without Emptying Your Position

Troops are both your expansion resource and your combat resource. Spending gold does not refill them on demand. This is why an economically rich position can still fail after an overcommitted attack.

The tagged client’s default attack amount is one fifth of the attacker’s current troops, but players can deliberately choose a different commitment. Treat the displayed amount as a risk decision rather than a recommendation.

For an early push, send the smallest amount that proves the route or tests the target. Keep enough current troops to survive the next credible response and preserve growth. A successful attack that leaves the economic core undefended can still be strategically losing.

| Situation | Safer troop decision | Why | |---|---|---| | Neutral expansion nearby | Commit enough to claim land while retaining a reserve | New land should not hollow out the home position | | Uncertain enemy border | Use the smallest push that tests the route | Enemy territory is a military and political commitment | | New exposed front | Hold troops back and stabilize | More territory can create a weak border | | Sudden neighbor pressure | Preserve a reserve for response | You should not abandon the economic core | | Faster-changing battle information | Recheck conditions before escalating | Player-versus-player attacks became roughly 10% faster in v0.34.2 |

Watch borders more closely than the center of your territory. Troop movement, repeated border pressure, an alliance change, or a neighbor running out of safer targets can all be warnings. Faster attacks mean stale information expires sooner, so use clear stop signals instead of committing every available troop.

FAQ

What is the best openfront build order?

There is no single fixed best order. Use LIMIT to identify whether your current constraint is border safety, troop capacity, current troops, gold, or a usable trade route. Then make one purchase that addresses that constraint and test it.

Should I buy a City early?

Buy a City when current troops repeatedly approach the existing maximum and will use the extra capacity. A City adds maximum troops, not immediate current troops, so it is less urgent when your army is far below the cap.

When should I build a Port or Factory?

Build a Port when an eligible, safe route can complete voyages. Build a Factory when connected City or Port stations actually settle Train Gold. Ports and Factories share their price counter, so buying one raises the cost of the next one in either category.

When is a Defense Post worth it?

A Defense Post is worth considering when its 30-tile zone covers an expensive approach. Use it to protect the border that would be costly or dangerous to lose, rather than placing it without a specific defensive job.

How much should I send in an early attack?

The default attack amount is one fifth of current troops, but you can choose a different amount. Send the smallest commitment that proves the route, while retaining enough troops to survive the next credible response and continue growing.
