1. How faction traits work
Every faction is a bundle of four things:
- Bonuses and drawbacks — percentage modifiers that apply everywhere the relevant activity happens. A mineral bonus speeds up both ship mining and colony passive mining; a solar bonus boosts ships in flight and colony solar arrays alike.
- A starting fleet — each faction opens with a different mix of ships (roughly equal total value) that points toward its intended playstyle. Every fleet includes one Destroyer escort.
- A starting cargo load — the freighters launch pre-loaded with faction-flavored supplies (miners carry extra ore, the military carries extra iron, and so on).
- A personality — when a faction is played by the AI, numbers for aggression, expansion, and exploration decide how it behaves. This is why playing against a faction feels different from playing as one. Each game the AI rolls its own temperament around those numbers: up to a tenth more or less aggressive, expansive and warlike, a liking of its own for particular worlds, and, about one game in three, a scout as its first UN-yard purchase instead of a second freighter. The table size pulls aggression too: in a duel every faction plays harder (there is only one rival, and every loss it takes is yours to gain), and at six or seven players a little warier (a fight in a crowd helps the onlookers). So a faction plays to type, but its opening and its first colony are not the same every game.
No faction changes the rules of the game. Everyone wins the same three ways — the table's Victory Point target (115 in a duel, down to 70 at seven players), a Sovereignty Charter from 200 Earth Influence, or the launch of a Lens telescope — and everyone runs the same colonize-and-grow engine described in the New Player Guide. A faction just tilts the board toward one road to victory.

3. Why the number of players changes everything
The game's own balance testing (about 4,600 AI-vs-AI matches, remeasured for v1.28.0 with the Victory Point target scaling by table size — 115 VP in a duel down to 70 at seven players — the AI's scouts, garrison battlestars and faction doctrine, piracy and escorts on the approach lanes, Reaver nests at the frontier, destroyers that claim sites, Jupiter's moons Europa and Ganymede, which the other factions contest, the UN yard closed until every faction has its colony grant, AI ships that use their faction's collection bonuses, science, with the Deep Sky Institute in the Mining Guild's place, the Lens telescope, a third way to win, since v1.27.0, and — since v1.28.0 — AI temperaments that differ from game to game) produced a striking pattern: which factions win depends heavily on how many factions are playing. Win rates against a random field, by total player count:
| Faction | 2p | 3p | 4p | 5p | 6p | 7p |
|---|---|---|---|---|---|---|
| United Defense Force | 50% | 30% | 16% | 15% | 10% | 9% |
| Free Traders Union | 59% | 40% | 33% | 20% | 18% | 18% |
| Titan Industries | 65% | 50% | 34% | 26% | 14% | 6% |
| Mars Colonial Authority | 47% | 24% | 22% | 18% | 19% | 12% |
| Outer Reach Explorers | 40% | 31% | 33% | 26% | 26% | 25% |
| Deep Sky Institute | 61% | 38% | 23% | 15% | 10% | 6% |
| Solar Dynamics Corp | 28% | 21% | 16% | 21% | 20% | 24% |
The story behind the numbers:
- Small games reward tempo. With one or two rivals, whoever grabs planets (or throats) fastest wins before anyone can out-produce them, and a duel's high VP target gives a science faction time. Titan wins 65% of its duels and leads the three- and four-player tables; the Deep Sky Institute wins three duels in five, many of them by launching its telescope, and the Free Traders win 59%. The Defense Force and the Mars Authority win about half their duels, the Outer Reach two in five.
- Nobody buys an extra ship in the opening. The UN yard takes no orders until every faction has its Colonial Initiative colony ship (around turns 14–20), so the factions that start with scouts — the Outer Reach and Solar Dynamics — get the first look at the system, and everyone else orders on the day the yard opens.
- Big games reward economies. With four or more rivals, the land rush splits the map thin and wars make you a target for everyone. The Outer Reach, built for the far worlds, holds above the balance line from four players up (a third of its games at four, a quarter after that), and it leads at six and seven, with Solar Dynamics (Mercury is its own) close behind; the Deep Sky Institute, the Defense Force and Titan fade in a crowd. (With more rivals, more of them come to blockade the Institute's telescope, and its own fleet can't guard the telescope and its colonies at once.) Jupiter's moons are contested: once one faction holds two worlds in Jupiter's system, the other AI factions race it for the rest, raid its lanes and go to war at its colonies. These numbers are AI-against-AI, so expect a real race for the lead. They will move as the factions' doctrines are tuned.
- The full seven-player table is a shorter game — with the target at 70 VP it is decided in about 430 turns, when most factions hold two or three colonies.
These numbers are how AI opponents behave, not a verdict on you — a human who plays a faction's strengths well beats its statistics. But they're a good guide to how hard a faction's road is at a given table size, and the setup screen uses this same data to label opponents as easy or hard for your chosen matchup.
Solar Dynamics Corp
Energy specialists with advanced solar collection technology
Strengths
- Energy is the game's real currency — it fuels travel, orbit entry, and the biggest share of every build cost — and SDC simply has more of it. Everywhere.
- Colony solar arrays and ship collection both benefit, so SDC colonies bank surpluses that refuel visiting freighters for free.
- The fusion bonus (+25% output, so 125 energy/turn per reactor) makes SDC the second-best outer-system faction after Outer Reach, and it arrives without Outer Reach's combat fragility. On an icy world local ice covers a quarter of the reactor's fuel, so SDC's ore lasts longer — but a colony running a Regolith Hydrogen Plant burns ore only; it makes water or burns it, never both.
- Mastered Regolith Hydrogen Plants: on Mercury and Venus, SDC turns sunlight into settler water at 4 energy per unit (everyone else pays 10) from cheaper plants — the energy faction's answer to the awkward fact that sun-rich worlds are dry.
Weaknesses
- The mineral drawback slows everything built from iron and silicon — ships, stations, upgrades — and shrinks Earth remittances, so Sovereignty is an uphill road.
- No head start: the fleet is modest, and none of the bonuses grab territory by themselves.
Playing as SDC
Colonize sun-drenched worlds and let energy do the buying. Mars or Eros first, then build Solar Arrays early and often — they pay double for you. Your freighters should always be moving: with fuel nearly free in the inner system, an SDC hauler runs routes other factions can't afford. Cover the mineral drawback by parking a Mining Operation over a rich reserve, and consider delivering energy to needy colonies — UN trade charters pay influence for energy too, and you're the faction with spare watts. Late-early game, your boosted fusion reactors make a Jupiter or Saturn colony practical while rivals are still hugging the belt.
Playing against SDC
The AI plays SDC cautiously (low aggression) and it starts slow — it wins fewer than one duel in three (28%) and one four-player game in six (16%), and it is near the top at a full table (24%). Deny it easy mineral income by claiming iron-rich worlds first and it struggles to convert sunlight into structures. Its colonies, though, are well-powered and their lasers never run out of energy — bring real numbers if you besiege one.
Deep Sky Institute
Scientists first, settlers second: labs, surveys and the long view
The Institute took the Asteroid Mining Guild's place in v1.26.0. Its game is science: studying worlds from orbit (S), building Research Labs in its colonies, and in the end launching a Lens telescope, the science victory.
Strengths
- Faster studies: 5 turns at an inner world, 6 in the belt, 8 at the giants and 9 beyond, where everyone else needs 6, 8, 10 and 12. In a race for a world's finding, the Institute usually gets there first, and every first finding pays Earth Influence (3 to 8) on top of the data.
- A Scout from turn one: it explores, and studies each world it reaches.
- A quarter more data from everything: labs make 2.5 a turn each instead of 2, and findings pay 50 to 113 instead of 40 to 90.
- The Heavy Freighter (960 cargo, 9000-energy tank), the best hauling and expedition hull in the game, on turn one.
- The shortest road to the telescope: anyone can build one, but the Institute gathers the data first, and the data counts toward catch-up and the time-limit standings even before the telescope starts.
Weaknesses
- −10% in combat, attacking and defending: its ships and colonies lose even fights.
- No edge in energy or ore, and Research Labs are silicon-hungry (120 each), so every lab is silicon not spent on a settler, a station or a delivery to Earth.
- A scout that studies isn't exploring, and a hauler that studies isn't hauling. Science pays slowly.
- The telescope is announced to everyone the turn it starts, and it takes at least 60 turns. Rivals come to blockade it, and with −10% combat the Institute is the worst faction at driving them off.
- A small-table faction: it wins 61% of its duels and 38% at three players, but 23% at four and 6% at a full table, where too many rivals come for the telescope at once.
Playing as DSI
Send the Scout out at once, and let it study each new world it reaches: the inner worlds take it only five turns. Settle somewhere worth a lab, build Mining Drills first, then a Research Lab or two. Keep the Destroyer with the Heavy Freighter once the truce ends, and don't let a hauler sit studying when it should be carrying ore. Watch the Science panel under Earth Influence: a rival with more findings than you is studying the same worlds you want. Before you start the telescope, build a finished Station somewhere you can defend and bank materials in your colonies: it pays as it goes, and every colony helps. Then keep enough warships at the station to outgun a blockade, but not so many that your other colonies sit bare: the AI raids them.
Playing against DSI
The Institute is the weakest fighter at the table, and its scouts sit still for turns at a time while they study: an easy mark for a lurker. Beat it to the nearest findings with a scout of your own, or simply out-settle it; its labs cost the silicon it would otherwise have spent on colonies. When its telescope starts, don't wait: park warships in that station's orbit to slow the work (declare war there to stop it), or raid the colonies that pay for it.
Mars Colonial Authority
Colonization experts with efficient settlement techniques
Strengths
- Starts with a Colony Ship — you can have a producing colony by roughly turn 10–15 (Eros in as few as 9 turns, Mars in about 16), while everyone else is still waiting for the UN grant at turn 12–20 and won't colonize until the mid-20s. And you still get the UN grant too: a second colony while most rivals are settling their first.
- Cheap settlers (800 E / 240 Fe / 160 Si / 80 W instead of 1000/300/200/100) make every expansion wave cost less, which compounds hard once your mature colonies start building their own colony ships at the five-year mark.
- Colonies are the biggest VP source in the game, and MCA simply gets more of them sooner. It wins nearly half its duels (47%) and sits a little below the balance line from three players up, closest to it at five and six (18% and 19%; 12% at a full table).
Weaknesses
- Every ship is 10% slower. Short hops barely notice; deep-space expeditions genuinely hurt. The faction motto might as well be "we said Mars, not Neptune."
- Wide empires are thin empires: many young colonies with 150 hull and three lasers are a buffet for an aggressive neighbor once the truce ends.
- Fades in crowded games — with six rivals the land rush splits too many ways for a head start to decide it.
Playing as MCA
Play the land rush you were built for. Send the starting Colony Ship to Mars or Eros immediately; aim the UN grant at Vesta or Ceres. Flag your third target with a Scout before rivals get ideas. Prioritize each colony's economy just enough to fund the next settler, and let the snowball roll — your win condition is hitting the VP target (115 in a duel, 70 at a full table) through sheer colonized acreage, plus stations at 25% each. The travel drawback says: stay compact. A dense, connected inner-and-belt empire beats a scattered one, and it's easier to defend when the knives come out around turn 24. A Defense Battery in each border colony is cheap insurance.
Playing against MCA
Speed is your advantage — MCA is literally 10% slower than you. Race it to the contested worlds: a Scout flag denies a planet outright, and every world you claim first cuts its VP engine. If it has snowballed anyway, its far-flung colonies are individually weak; an armed faction can convert two or three of them into its own VP (captures pacify from 50% toward 85% over time). Don't let the early game go quietly — a Mars Authority left alone for thirty turns is the hardest faction to catch.
Outer Reach Explorers
Pioneer explorers with deep-space technology
Strengths
- Two Scouts on turn one, aimed at the game's 47-VP exploration pool: the first faction to orbit each planet banks +2 VP (inner) or +3 VP (outer), permanently.
- Cheap fusion (600 E / 300 Fe / 225 Si per reactor) unlocks the outer system early — and the outer worlds carry the biggest colony VP in the game (Saturn 15, Neptune 22, Makemake 27), plus most of its water, and local ice now covers a quarter of a reactor's fuel there: an ORE outpost among the ice giants provisions its own settlers.
- Reliable engines mean less wear on every burn and safer use of higher thrust — exactly what a faction living in deep space needs. The Heavy Freighter rounds out a real expedition kit.
Weaknesses
- The worst mineral income in the game (−15%) — ORE settles only as fast as it can afford to.
- Fragile in a fight (−10% defense) with no warship heavier than a Destroyer to start.
- The strategy is a slow burn: deep-space payoffs take years to arrive — though wildcat-era explorer appetite and supply logistics have made ORE a contender at every table size (40% of duels, 33% at four players), and above the balance line from four players up (25% at a full table).
Playing as ORE
Open with the great scattering: both Scouts outbound on day one, sweeping first-orbit VP and flagging the worlds you'll want later. Survey missions from the UN pay influence for trips you were making anyway. Still, don't skip the boring part — you need one solid inner or belt colony (Vesta or Ceres) as an economic anchor, because your mineral drawback makes bootstrapping slow. Mid-game, do the thing only you can do cheaply: a fusion-powered colony at Jupiter or Saturn, supplied by the Heavy Freighter's enormous tank, while rivals fight over Mars. Avoid wars; you're bad at them, and your VP comes from places nobody else has reached yet.
Playing against ORE
Contest the scout race in the first ten turns — every first-orbit you take is permanent VP it never gets. The AI plays ORE peacefully (aggression about 0.2) and it defends poorly, so its far-flung, thinly-guarded outposts are vulnerable — but they're also far away, which is its own defense. Usually the winning move is simpler: outgrow it in the inner system while its investment is still in transit to Neptune.
United Defense Force
Military faction focused on dominance through force
Strengths
- The only faction that can bombard and capture from turn one — the starting Battlestar is the game's premier warship, and conquest is a real VP engine (captured colonies start at 50% of planet VP and pacify to 85% if held).
- The combat bonus applies to attack and defense, so UDF wins fair fights and shrugs off retaliation better than anyone.
- The Battlestar doubles as a mobile base: it can build Scouts, stations, Mining Operations, and Military Outposts anywhere.
Weaknesses
- The worst economy in the game: −12% on everything. Every turn spent not fighting is a turn UDF falls behind.
- Unreliable engines wear the fleet down between battles.
- War has legal bills: breaching a truce brings UN peacekeeper waves, and every kill multiplies your Earth Influence decay 5× for 10 turns — Sovereignty is effectively closed to a warring UDF.
- Fades fast in bigger games (15% at five players, 9% at a full table): fighting everyone means everyone fights back — and repossession law means conquests must be garrisoned through a years-long contest window before the UN recognizes them.
Playing as UDF
Even the war machine needs a peacetime economy — the opening 24-turn truce is your buildup phase, and you should use it exactly like everyone else: colonize with the UN grant, mine, and get a station started (Mars or Eros; the colony will fund it). The difference is what happens at turn 24. Pick one neighbor — ideally a fat, soft target like an overextended Mars Authority — and take a colony or two with bombardment (K) and capture (G) — but check the founding date: colonies under two years old are under UN colonial protection, and touching them brings peacekeepers even in declared war. Seizing one anyway goes on your permanent record — each offense slows the pacification of all your ill-gotten conquests and escalates the UN's response. Once may be worth it; a habit never is. And garrison what you take: until a conquest pacifies to 75%, its former owner can retake it lawfully — no truce, no protection, no peacekeepers will stop them. Don't breach truces; declared war carries no UN penalty. Consolidate, repair at your station, let captures pacify, then pick the next target. Serial wars, not parallel ones. In small games this tempo is devastating; in large ones, restraint and target selection are everything.
Playing against UDF
The AI UDF (aggression about 0.85, a little higher in a duel) is the faction that will actually besiege your colonies after the truce ends. Prepare like it's weather: Defense Batteries at exposed colonies, a Destroyer garrison (best point-defense in the game), and a finished station — tuned so a lone raider can never crack it. Then remember UDF's secret: it's poor. Every siege it mounts costs energy and iron it collects 12% slower than you. Turtle, trade, and outgrow it — or accept the local truce it's offered at your planets and let it exhaust itself on someone else.
Titan Industries
Manufacturing giants with rapid ship production
Strengths
- Everything with an engine comes off the line faster — freighters, warships, even colony ships. Over a long game that's a permanently larger fleet for the same resources.
- The most reliable engines in the game (tied with no one at +25%): less hull wear per burn, and the safest faction to push the thrust slider with.
- Two Destroyers on turn one make TI surprisingly hard to bully early, without the UDF's economic penalty.
Weaknesses
- The build bonus needs a shipyard to apply to — and TI builds its own stations 20% slower (roughly 19 turns instead of 15). The faction's engine has a slow ignition.
- No collection bonus of any kind: TI's economy is strictly average, so its advantage only shows once resources are flowing into hulls.
- Tempo fades with scale: it wins 65% of its duels and leads at three and four players (50% and 34%), and falls well below the balance line at a full table (6%). The AI's first order at the UN yard is a Colony Ship, built 20% faster than anyone else's — the fast second colony is where TI's yard pays off.
Playing as TI
Your goal is to get a station running, because that's where the +20% starts compounding. Colonize early (Mars or Vesta), start the station immediately and let the colony bankroll it — yes, it takes roughly 19 turns; start it sooner to compensate. While it builds, the UN Station at Earth is your interim yard. Once your own yard opens, out-produce everyone: freighter fleets for logistics, a Battlestar in 9 turns instead of 10, and replacement hulls faster than rivals can sink them. TI can pivot to whatever the game demands — trade fleet, settler wave, or war machine — it just does it with more ships.
Playing against TI
TI is weakest before its first station finishes — that's your window to claim the contested planets, or (if you're the aggressive type) to raid. A half-built station is capturable; a finished one is a fortress. Once its yards are humming, avoid attrition wars — it replaces losses faster than you — and race it on VP instead: its middling aggression (about 0.5) means it hunts ships but rarely besieges well-defended colonies.
Free Traders Union
Commerce-focused faction with enhanced cargo capacity
Strengths
- Three bonuses — the biggest kit in the game. Freighters hold 455 (Light) and 1248 (Heavy) instead of 350/960, and the +25% trade rate improves every deal: Earth remittances, UN trade charters, missions, proposed trades (U), and the AI market — FTU buys ore cheaper and sells it dearer than anyone, and as the faction most willing to run merchant errands it is the one most often seen selling a colony's surplus to a neighbour.
- Cheap settlers (750 E / 225 Fe / 150 Si / 75 W — the cheapest in the game) mean the caravan can found colonies while it trades, fixing the classic trader problem of ending the game rich and landless.
- A strong small-table record (59% of duels, 40% at three players, 33% at four), and above the balance line even at a full table (18%).
Weaknesses
- The worst engines in the game (−30% reliability): FTU ships nick themselves constantly and need repair stops. Keep them near colonies and stations that can patch them up.
- Militarily meek: a small attack penalty, no starting warship beyond the Destroyer, and a fleet of fat, valuable freighters that pirates dream about.
Playing as FTU
Run both engines at once — that's the whole trick. Engine one: the trade loop. Mine and haul ore to Earth (press E at Earth to deliver), fill UN charter requests to needy colonies at 1.5× rates, complete missions — all at your +25%. Engine two: the settler loop. Your discounted colony ships should be founding a modest empire — two or three colonies for ore supply, VP, and freighter repair bays along your routes. Influence decays 1.5%/turn, so steady beats spectacular: a regular shuttle rhythm to Earth wins the Sovereignty race at equilibrium. Stay out of wars; combat kills traders and 5× influence decay kills charters.
Playing against FTU
The Traders win on the influence track while others brawl, and the rate bonus makes them fast at it. Check the standings regularly; if FTU's influence is compounding, the clock is real (it also needs colonies on 3+ planets and a 10-year-old colony, so early denial of territory slows the charter). Its physical empire is soft — weak escorts, fragile engines — but raiding it costs you influence and invites UN complications if truces are involved. The reliable counter is pace: win the VP race before the trade engine matures.
4. Things to try
- Play the same two-opponent map as Mars Colonial Authority, then as the Deep Sky Institute. One race is for land, the other for findings: count how much Earth Influence your findings alone bring in.
- As UDF in a Tourist game (no opponents), practice a siege on a UN-neutral world's timing: how many turns does your Battlestar need to bombard a station down, and what does the return fire cost you?
- As FTU, track your Earth Influence for twenty turns of steady deliveries, then stop delivering and watch the decay. Equilibrium — income versus decay — is the whole Sovereignty game in miniature.
- Set up a 6-player game and watch the AI factions from the sidelines with a passive faction like SDC. Who attacks whom after turn 24, and who's ahead at turn 100, usually matches the win-rate table above.
- As ORE, count how much of your final score came from exploration firsts alone. The 47-VP pool is about two-fifths of a 115-VP duel win.
