What OpenFront Is and Why the Basics Matter
OpenFront explained starts with one practical idea: you control territory, manage population, and choose when to commit troops. Small interface decisions can determine whether an attack expands your position or leaves your border exposed.
OpenFront is an open-source, browser-based RTS. The community wiki organizes its knowledge around mechanics, combat, gold, bots, nations, buildings, ports, atom bombs, warships, transport ships, trains, and settings. That range matters because the game is not only about clicking an opponent: movement, access, economy, alliances, and map shape all affect the choices available to you.
The safest way to learn is to treat every action as a question of access and commitment. Before attacking, check whether you share a border. Before using water, check whether you have water access. Before expanding, consider whether the new territory improves your position or creates another vulnerable edge.
| Area | What the sources identify | |---|---| | Game type | Open-source, browser-based RTS | | Core topics | Combat, gold, bots, nations, buildings, ports, ships, trains, settings | | Beginner focus | Learn controls and expand during the opening minutes | | Current community wiki label | Latest: v0.34.0 |
The game’s guide directory also highlights decisions that commonly become important after the opening: whether to grow tall or wide, how to form a team spawn, how to defend an island, when to build a Defense Post, and how to assess threats across the board.
For a new player, the useful priority order is simple:
- Learn the click and menu controls.
- Understand which targets are legal.
- Adjust troop commitment before repeated attacks.
- Keep enough defense for the borders you already own.
- Use diplomacy deliberately, because ending an alliance has a stated penalty.
Controls, Menus, and Legal Targets
The basic controls determine what you can do before strategy even enters the picture. Left-click attacks the selected player, but it does not work unless you share a border with that player. This makes borders a hard requirement for ordinary attacks.
Right-click opens the Radial Menu. Space hides nation borders so you can see the terrain those nations occupy. At the bottom left, two sliders control your troop-to-worker ratio and the share of your troops used per attack.
| Control or icon | Reported function | Important restriction | |---|---|---| | Left click | Attacks the selected player | Requires a shared border | | Right click | Opens the Radial Menu | None stated | | Space | Hides nation borders | Lets you view occupied terrain | | Sword icon | Attacks the selected area | Disabled for yourself, water, inaccessible land, or an ally | | Boat icon | Sends a transport boat to attack | Disabled without water access | | Red X icon | Exits the Radial Menu | None stated | | Wrench icon | Opens the Build Menu | None stated | | Gray info icon | Shows selected-player information | Additional interaction icons may appear |
The radial menu is especially useful because it makes unavailable actions visible rather than forcing you to guess. A grayed-out Sword icon tells you that the selected target is not a valid ordinary attack target. The source lists several reasons: you selected yourself, water, land you cannot access, or an ally.
The player-information view supports diplomacy. You can send an emoji, request an alliance with the handshake icon, or mark a player to allies with the target icon. Once allied, the available interactions change: you can donate troops with the donation icon or betray the ally with crossed swords.
Do not treat betrayal as a casual shortcut. The supplied guide says it ends the alliance, gives a permanent traitor debuff that makes others less likely to ally with you, and reduces your defenses by 20%. If you are relying on a border arrangement for safety, that defense loss can matter immediately.
Population, Territory, and Attack Decisions
Territory has value because it contributes to maximum population. An older attacking guide, marked as potentially out of date and last updated for v23.0, describes maximum population as depending on tiles owned, city levels, game difficulty for certain players, and player type. Use its formulas as historical mechanics reference rather than a guarantee for the current client.
For human players outside “infinite troops” mode, that guide gives the following structure:
| Component | Formula or stated effect |
|---|---|
| Maximum population | 2 × basePop + cityBonus |
| Base population | numTilesOwned^0.6 × 1000 + 50000 |
| City bonus | sumOfCityLevels × cityPopulationIncrease |
| City population increase | 25,000 per city level contribution |
| Other influences | Difficulty and whether the player is human or a bot |
The practical lesson is not that you should expand without limit. More tiles raise capacity, but expansion can also create new borders. The newer guide directory specifically frames the decision as “tall versus wide,” asking players to test liquidity, access, need, and deadline before turning a compact core into a second foothold.
Population growth is also described in the older guide as balancing current population against maximum population. Its stated per-tick formula is:
(10 + currentPopulation^0.73 / 4) × (1 − currentPopulation / maxPopulation)
The same source says the formula is optimized at roughly 42% of maximum population. Since that source warns that its accuracy may be compromised, avoid making exact current-game decisions from the percentage alone. Instead, use the broader principle it illustrates: troops, workers, current population, capacity, and attack commitment are connected.
| Decision | What to check first | |---|---| | Ordinary attack | Whether you share a border | | Water attack | Whether you have water access | | Repeated attacks | The slider controlling troops used per attack | | Expansion | Whether it improves access and shape | | Building capacity | Territory and city-level contribution | | Alliance break | The permanent traitor debuff and 20% defense loss |
A strong early-game habit is to make smaller commitments until you understand the situation. The guide directory recommends small probes when trying to close a pocket, verifying the inland-cluster rule, keeping a second route after a transfer, and avoiding overextension. Even without relying on undocumented details, that mindset is sound: preserve options while confirming what the map allows.
Water, Teams, and Changing Modes
Water changes which attacks are possible. The Radial Menu’s Boat icon sends a transport boat to attack the selected area, but only if you have access to water. The guide directory further describes transport landings as a process of choosing a reachable coast, capping each wave, placing a Warship screen, building a beachhead, and canceling a failing operation before it drains the home front.
That advice points to an important distinction: reaching a coast is not the same as holding it. A transport operation can pull resources away from your original territory, so assess the security of your home front before committing to a crossing.
| Situation | Relevant reported guidance | |---|---| | Planning a water landing | Choose a reachable coast and cap each wave | | Landing defense | Use a Warship screen and establish a beachhead | | Failing operation | Cancel before it empties the home front | | Island defense | Screen transports, place a Port and Defense Post | | Disconnected sea route | Fall back to land | | Warship condition | Yellow stripes relate to veterancy and repair decisions |
Teams introduce another set of tradeoffs. The guide directory recommends reading teammate rings, preserving one neutral lane per player, and choosing between a connected edge arc or a deliberate split. It also advises teams to reserve space for Cities, Factories, Ports, and rail corridors, name the payer, and stop when a shared route no longer survives.
The current community wiki notes recent additions including trusted-only lobbies, public profiles, player reporting, a full lobby browser, cosmetics inventory, and four new maps. It also lists Doomsday Clock as a battle-royale zone gamemode in v0.33.0. For mode-specific rules, consult current in-game information and up-to-date wiki pages, because older pages may not reflect later releases.
FAQ
What does “openfront explained” mean for a beginner?
It means understanding the basic loop: control territory, manage troop commitment and workers, choose legal targets, and avoid exposing your borders. Start with the controls before attempting complex water or team strategies.
Why can’t I attack a player with left click?
The supplied controls guide says left-click attacks require you to share a border with the selected player. If you do not share one, the attack will not work.
What does the Boat icon do?
The Boat icon sends a transport boat to attack a selected area. It is unavailable if you do not have access to water.
What happens if I betray an ally?
Betrayal ends the alliance. The source says it also gives a permanent traitor debuff, makes other players less likely to ally with you, and causes you to lose 20% of your defenses.
Should I always take more territory?
No. More territory can increase maximum population capacity, but the guide directory recommends weighing liquidity, access, need, and deadline before expanding from a compact core.
