OpenFront Nation Difficulty: What Easy, Medium, Hard and Impossible Actually Change

The short answer: the difficulty selector offers four options — Easy, Medium, Hard and Impossible — and it changes exactly one thing: how strong the AI Nations are. It never touches your own account or the human Bots; only the Nations you fight get retuned. Read the three numbers it moves — Nation starting troops, their cap multiplier, and their growth rate — and your choice becomes a decision instead of a guess you discover mid-match.

Direct answer: the difficulty only retunes the AI Nations

The single-player and private-lobby difficulty selector has four options, and the first thing to internalize is that it is a one-sided dial, not a global power button. It changes the strength of the AI Nations and nothing else. Your own starting troops, your gold, your build times, your unit costs, and the human Bots in the lobby are all completely independent of the setting — a human always starts with 25,000 troops and runs the standard cap formula at full strength, no matter which level is selected. Only the Nations are retuned, and they are retuned in three linked ways at once. First, their starting troop count changes: 12,500 on Easy, 18,750 on Medium, 25,000 on Hard, and 31,250 on Impossible. Second, the multiplier applied to their maximum troop cap changes: x0.5, x0.75, x1.0 and x1.25 across the same four levels. Third, the growth rate at which they refill after a fight changes: x0.9, x0.95, x1.0 and x1.05 applied after the ordinary growth formula. These three effects are not independent; they compound. A Nation on Impossible does not merely “have more troops” — it starts with a bigger army, is allowed to keep a bigger army, and refills a little faster, and those three effects stack on every tile and every city it accumulates. The headline consequence is that Hard is the level where the Nations fight on exactly human terms: the same 25,000 start, the same x1.0 cap, the same x1.0 growth as you. Easy and Medium are deliberately softened so that the Nations start below you and hold a lower ceiling; Impossible is deliberately amplified so that they start above you and hold a higher one. The reason most of the confusion in the community exists is that people treat the setting as a flat “250% income cheat.” It is not. It is a controlled set of multipliers on the Nations’ opening strength, their ceiling, and their refill speed. Read those three numbers, look at how many Nations the chosen map actually places, and the choice becomes a decision you can reason about. Once the level is set, the rest of your plan is ordinary single-player play: understand the refill calculation the difficulty scales, and decide whether buying peace with a Nation is worth the rising gold price at higher levels. The next step after choosing a level is figuring out how to actually put that Nation under pressure and win the borders it holds, which is covered in the companion guide on how Nations put you under pressure, and if you are aiming specifically at the campaign medal at the top level, the campaign and medal path on Impossible is its own focused guide.

The four-tier table: the exact v0.34.21 numbers

This is the verified data from the tagged configuration, not the rounded community folklore. Use it as the reference you check every wiki and video against, because the widely published figures have drifted from the source and several players have built strategies on numbers that are no longer true. The table below is what a v0.34.21 game actually loads for each level.

Your human baseline, for comparison, is 25,000 starting troops and a cap multiplier of exactly x1.0. Bots are separate and untouched by this setting: whether you count them as allies or as noise, they always start with 10,000 troops and run at one third of the normal cap, so they are a constant across every level and you can plan around them without re-reading the table. Now notice what the table does and does not do, because that is where the misconception lives. The setting does not change your starting gold, your build timers, your unit costs, or the number of Nations the map places; the selector retunes the Nation side only. That means a Nation on Impossible is not “a bigger number” in a single sense — it starts with a larger army, is permitted to keep a larger one, and refills slightly faster, and those three effects compound on every tile and every City it owns. A same-sized Nation on Impossible can therefore outlast an exchange that would be even at Medium, purely because its ceiling and its refill let it absorb the same hit and come back bigger. That compounding is the entire reason the level matters, and it is the entire reason the published wiki table and the popular “Hard adds a 50% bonus” claim are both wrong. The real value of Hard is a multiplier of 1.0, which is human parity, not a 50% bonus. If you have been losing at Hard and assumed the Nations were secretly running a 1.5x or 2x economy, that assumption is costing you: the actual gap is a modest, compounding advantage in starting strength and refill speed, and a modest, compounding advantage is exactly the kind of gap that a structural edge — more Cities, more Ports, a walled region, Nations busy fighting each other — can overcome, whereas a phantom 2x economy would have made the level unwinnable. The table is the floor; understanding the compounding is what turns it into a plan.

The growth curve: why Nations feel faster early and slower near their cap

Troop refill is not a flat rate, and this is the detail that most players miss because it is not printed anywhere in the UI. The base formula adds 10 + troops^0.73 / 4 per tick, then multiplies that by 1 - troops/max, so the gain shrinks as you approach your ceiling and trends toward zero as your army reaches its maximum. The same curve applies to Nations, with the difficulty multiplier applied afterward, and two consequences follow that directly shape how you should play each level. First, refill is steepest early in the game, when troops/max is low and the ratio is close to 1, and it flattens as the army nears its cap. An Impossible Nation that starts at 31,250 and holds a 1.25 cap is at a lower fraction of its ceiling at the open than a Medium Nation at 18,750 against a 0.75 cap, so it starts bigger and refills harder in the first minutes — the two effects, the high start and the high ceiling, line up to make the early Impossible pressure feel much sharper than the raw starting number suggests. Second, because the curve is concave, two Nations of similar size refill at nearly the same rate, but a Nation that has been pushed well below its neighbors can rebuild faster than one that is already sitting at its ceiling. That is why a hard early exchange that drops you below your rivals leaves you slowly refilling a bigger deficit rather than a smaller one: the curve is doing work against you the further below your ceiling you sit. The practical read is that at Medium and below, the Nations start small enough that their early curve advantage is modest and you can outrun it with early land; at Hard and Impossible, the Nations start at or above your own troops and refill at human or faster-than-human speed, so the early pressure is real and the margin you must manufacture with Cities, Ports and territory is larger. The cap itself is computed as 2 * (tilesOwned^0.6 * 1000 + 50,000) + cityLevels * 250,000, so Cities are the lever that raises your ceiling in absolute terms, while the difficulty scales that same ceiling up or down on top. Land and Cities set the size of the reservoir; the difficulty sets how full you are allowed to fill it. A player who has more Cities at the mid-game has the bigger reservoir regardless of multiplier, which is why the winning shape at high levels is to convert early territory into Cities quickly, because every City you own raises your absolute ceiling by 250,000 of the formula and the difficulty multiplier applies to yours and theirs equally, meaning the side with more Cities ultimately holds the larger reservoir and the larger refill base.

Behavior: the level changes how Nations think, not just how big they are

Beyond the three headline numbers, the difficulty retunes how the Nations actually make decisions, and this is the effect that is easiest to underestimate because it is the least visible in a single match. Nations do not attack on a fixed timer — they decide per decision step whether a strike is worth it, and the gates that decide that tighten with difficulty: an Easy Nation skips about three of every four attack checks against a human and never betrays one, a Medium Nation still skips about one in four, but a Hard or Impossible Nation never skips and will only commit a strike it judges strong enough (on Hard and Impossible a strike that falls below roughly a fifth of your force is treated as too weak to be worth it), so a single Nation’s frontier pressure at Impossible is a sustained, repeated hammer rather than the occasional push you get at Easy. The number of Bots a single Nation will call into a coordinated strike climbs steeply with the level: one on Easy, one to two on Medium, about three on Hard, and up to the full available pool on Impossible. That is the difference between a Nation that nudges a border at Easy and one that concentrates a multi-Nation push at Impossible, and it is why the failure mode at high levels is not a single bad trade but a coordinated multi-front hit that you cannot answer from one side. The relationships are retuned the same way: the gold offering required to improve your standing with a Nation climbs from roughly 1x on Easy to roughly 10x on Impossible, and on Hard and Impossible Nations will refuse to ally with a player who already holds too many alliances. That last rule quietly changes the whole alliance game at high levels — on Easy you can be friends with almost everyone, but on Impossible you cannot buy your way into a full set of alliances and you have to choose which Nations to keep and which to let burn. The ballistic behavior also sharpens: at Hard and Impossible the Nations try to avoid trajectories that their own or a neighbor’s SAM would intercept, and Impossible Nations evaluate far more nuke-target candidates and will even strike a SAM installation with an over-leveled nuke if no safe spot exists. On Easy, by contrast, the Nations do not betray a human at all. Read all of this as a single point: the low levels give you slower, smaller, more forgiving opponents, and the high levels give you faster, more coordinated, more demanding ones. The numbers in the table are the floor of that gap; the behavior is what makes Hard and Impossible qualitatively different, not merely larger. A common trap is to lose at Hard, look at the starting-troop table, see that the Nations start at exactly your 25,000, and conclude “Hard is just Medium but the numbers are the same,” when in fact the real differences at Hard are the no-skip, strength-gated attack behavior, the three-Bot coordinated strikes, and the alliance-refusal rule — the numbers are parity, but the behavior is not, and that behavior is what separates a Hard win from a Hard loss.

Correcting the circulating numbers: the wiki and the “bonus” claims

Two widely shared figures are wrong as of the tagged source, and they are worth naming explicitly because players will encounter them in wikis, videos, and threads and will quietly lose trust in the real table if they are not corrected. The first is the community wiki’s Difficulty page, which lists Nation starting troops of 2,500, 5,000, 20,000 and 50,000 with cap multipliers of 0.5x, 1x, 1.5x and 2x. Those are outdated values from an earlier version of the game; the v0.34.21 source uses 12,500, 18,750, 25,000 and 31,250 with multipliers of 0.5, 0.75, 1.0 and 1.25. If you have been building a strategy around “Impossible Nations have double the cap,” you have been overestimating their ceiling and underestimating how much of the gap is starting strength and refill speed rather than a flat 2x. The second misconception is the popular Reddit-style claim that “Hard adds a 50% bonus to troops and growth” and “Impossible adds 100% or 250%.” The source refutes both: the Hard multipliers are exactly 1.0, which is human parity, and the Impossible multipliers are 1.25 on cap and 1.05 on growth. Neither is a 50% or 100% addition, and the “250%” figure does not correspond to any real multiplier in the configuration. A third, subtler correction is useful for anyone who has read a video suggesting that choosing a harder level also buffs the human: the setting never changes your human numbers, and a harder level makes you exactly as strong as the medium one while making the Nations stronger, so a harder level is strictly harder for you, never easier. The honest read is that the difficulty axis is a Nation-only dial, and the single most important correction for someone who has been losing at Hard is to stop treating it as a cheat code and start treating it as a human-parity game. You are meant to beat Nations that are exactly as strong as you, so the gap between a Hard win and a Hard loss is skill, not numbers, and the winning play is to manufacture a structural edge — more Cities, more Ports, a walled region, and Nations that are kept busy fighting each other — rather than to look for a number that the setting is not giving you. Once you internalize that the numbers are parity at Hard and a modest compounding advantage at Impossible, the strategy stops being “survive the buff” and starts being “out-position and out-City the opponent,” which is a far more actionable frame and a far more likely path to a win at the levels that have been frustrating you.

Scenario 1: an Easy or Medium run where the goal is a clean, fast win

Suppose you are playing a single-player game on the World map with the default Nation count, in FFA, and you select Medium. You start with 25,000 troops, and every Nation starts at 18,750 with a 0.75 cap. The decision frame is simple: take land quickly, keep your core behind one or two defensible frontiers, and use your size advantage to trade up. Because the Nations start below you and refill at 0.95 of the human rate, every border fight you open is one you open larger. The plan is to secure a first pocket, push the weakest visible neighbor in the first few minutes while the Nations are still at 18,750 and far from their cap, and convert that opening into the land that raises your own ceiling through the 2 * (tiles^0.6 * 1000 + 50,000) term. Cities are still the ceiling lever, so place your first City behind the pocket rather than on the exposed edge. The numbers that matter here are the margin: at a 0.75 cap, a fully strong Nation holds less than you, so even a 1,000 to 2,000 troop advantage at a border is recoverable if you keep adding land. The failure mode is the opposite of the Impossible one — it is over-committing to one Nation and exposing a second frontier while the first is still contested, which at Medium can put you on two fronts against Nations that refill at nearly your speed. On Medium the Nations still skip about one attack check in four against you and can pull one to two Bots into a strike, so hold a reserve rather than flattening every border at once. If you want the fastest clean win, Medium with early land-taking is the level where the math favors the human most, because the Nations’ early curve advantage is modest and your size lead is real from the open. If you instead select Easy, the frame is even cleaner: the Nations start at 12,500 with a 0.5 cap, attack slowly, and never betray you, so Easy is a forgiving sandbox for learning the mechanics with minimal pressure, and the only way to lose is to be genuinely careless with your frontiers. The useful discipline at both of these levels is the same: do not let the low pressure tempt you into ignoring border management, because the moment a second Nation grows behind your first, the margin that made Easy and Medium winnable evaporates and you are fighting two refilling opponents with one reserve.

Scenario 2: a Hard or Impossible run where the goal is to actually finish the game

Suppose the same World map, but you select Impossible this time. You start with 25,000 troops, and every Nation starts at 31,250 with a 1.25 cap and a 1.05 refill. The honest read is that you start below the Nations, below their ceiling, and behind on refill, so the winning frame is not “out-trade them head-on” but “manufacture a structural edge they cannot refill past.” That usually means three things. First, choose a spawn that lets you wall a region or an island so you face only one or two Nation borders at a time instead of the default spread, because at Impossible a single Nation can concentrate up to the full Bot pool into a coordinated push and you want to answer one front at a time. Second, race to the Cities and Ports that raise your absolute ceiling, because the cap formula only grows with land and City levels and the 1.25 multiplier works on yours and theirs — the player who holds more Cities ends up holding the larger reservoir regardless of the multiplier, so Cities are the single most important mid-game objective at Impossible. Third, use the relationships economy deliberately: at Impossible the gold offering to improve a relationship is roughly 10x, so buying peace with a specific Nation is expensive, and it usually pays to let the Nations fight each other rather than paying to keep every border friendly. The numbers that decide the win: if you can get your land and Cities to the point where your 1.0 ceiling exceeds a rival Nation’s effective ceiling, you have turned the multiplier against them, because their 1.25 advantage is a fixed fraction while your City count is a variable you control. The failure mode is trading head-on at a border and losing slowly, because the 1.05 refill means the Nation you just damaged rebuilds faster than you can close the same gap. On Impossible you are not overwhelmed by a 250% cheat; you are overwhelmed by a modest, compounding advantage, and a single structural edge — more Cities, more Ports, a walled region, and Nations busy with each other — can overcome it. The practical tempo is to survive the first two or three minutes without a large head-on exchange, wall your core, and convert every safe tile into a City, because the game at Impossible is a mid-game cap race, not an early-game troop exchange, and the player who holds more Cities at the half-hour mark is usually the player who wins.

Failure modes, and picking the level by mode and map

The most common defeat at Easy and Medium is boredom-induced over-extension: the Nations are weak enough that players stop managing their borders, let a second Nation grow behind the first, and get flanked. The counter is the same at every level — never flatten every border at once, hold a troop reserve, and check the weakest-neighbor rule before each attack so you trade up rather than trade flat. The most common defeat at Hard is assuming the Nations are “slightly stronger” when they are actually at human parity: same start, same cap, same growth, but with no-skip, strength-gated attack behavior and three-Bot coordinated strikes. The counter is to stop measuring yourself against the Nations and start measuring yourself against your own ceiling — a Hard win is won by holding more land and more Cities than the Nations around you, not by matching their troops at a single border. The most common defeat at Impossible is the early all-in on a Nation that started at 31,250 and refills at 1.05; the counter is to avoid the first big exchange, wall your region, and let the Nations spend on each other while you build the City and Port base that raises your ceiling above theirs. A fourth, cross-cutting failure is misreading the map’s Nation count: because the difficulty dial only scales the Nations, a map that places many Nations multiplies the number of opponents you must out-cap, so the same Impossible is far harder on a dense map than on a sparse one. Check the actual Nation count of the map you are playing before you trust a difficulty label, and treat “Impossible on a populated map” as a different challenge from “Impossible on a small map” even though the selector value is identical. Now the level choice itself: the selector is a tool, not a ladder, so pick the level that matches what you are trying to do. If the goal is to learn the game quickly or to finish a low-pressure run, Easy is the cleanest setting — Nations at half your ceiling, starting at 12,500, attacking slowly, and never betraying you, which makes it a forgiving sandbox. If the goal is a normal single-player win with some real pressure, Medium is the default and the level where the human math favors you most, because the Nations start at 75% of your troops and hold a 0.75 ceiling. If the goal is to test whether your skill holds against opponents who are exactly as strong as you, Hard is the honest benchmark: human parity on every number, plus the added pressure of faster, more coordinated Nation attacks. If the goal is a deliberate challenge against amplified Nations, Impossible is the setting, and it is a compounding advantage — 1.25 cap, 1.05 refill, 31,250 start — not a flat cheat. Two cross-cuts matter. First, the mode matters: in Teams the Nations on your own team also scale with the setting, so a higher level gives you stronger allies but also stronger enemies, and the net effect depends on whether your team has more Nations than the opposing team, which makes the level more neutral on a balanced Teams map than in FFA. Second, the Nation count matters more than the label: a sparse map on Impossible is beatable by a structural edge, while a dense map on Hard can feel as hard as a dense Impossible, because the difficulty multiplies the number of Nations you must out-cap. Pick the level, then verify the map’s Nation count and the mode, and only then trust the setting to do what you expect — the selector is the dial, the map and the mode are the amplifier.
