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.
No faction changes the rules of the game. Everyone wins the same two ways — 100 Victory Points, or a Sovereignty Charter from 200 Earth Influence — 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 4,400 AI-vs-AI matches, remeasured after the trade, wildcat-mining, and water systems landed) 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 | 76% | 42% | 29% | 15% | 16% | 13% |
| Free Traders Union | 72% | 49% | 26% | 28% | 20% | 18% |
| Titan Industries | 71% | 46% | 31% | 29% | 16% | 14% |
| Mars Colonial Authority | 57% | 49% | 42% | 29% | 21% | 11% |
| Outer Reach Explorers | 49% | 38% | 33% | 23% | 13% | 13% |
| Asteroid Mining Guild | 11% | 9% | 9% | 12% | 19% | 17% |
| Solar Dynamics Corp | 11% | 2% | 4% | 4% | 12% | 16% |
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. The Defense Force wins three duels in four (repossession rights let its victims strike back); Mars Authority — its young colonies under UN colonial protection — leads the three-to-five player middle.
- Big games reward economies. With five or six rivals, the land rush splits the map thin and wars make you a target for everyone. The Guild's ore trade and Solar Dynamics' slow engine climb steadily with table size.
- The full seven-player table stays close — every faction lands within 11–18% of the balanced 14.3%, so faction choice there is about playstyle, not power. (Solar Dynamics is even third there — the slow engine finally pays in a crowd.)
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.
- 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 — its measured win rates are the lowest in the game at small table sizes. 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.
Asteroid Mining Guild
Expert miners focused on mineral extraction
Strengths
- The best mineral income in the game, applied to ship mining and colony drills alike — and minerals are what stations, fleets, and Earth remittances are made of.
- Starts with the Heavy Freighter (960 cargo, 9000-energy tank): the single best hauling and expedition hull, on turn one.
- The natural Sovereignty faction: ore flows to Earth at 0.04 (iron) and 0.08 (silicon) influence per unit, and nobody fills a freighter faster.
Weaknesses
- Slower refueling everywhere; the solar drawback stings most on long hauls.
- The Heavy Freighter is worth 85% of its cargo in salvage to whoever destroys it — pirates and warlords notice. Escort it once truces lapse.
- Needs time and space: measured win rates are dismal in duels (11% at two players) and only climb in crowded games.
Playing as AMG
Head for the belt. Ceres (iron + silicon, 12 VP) is the Guild's spiritual home, with Psyche's 6000 iron next door. Colonize, stack Mining Drills, and set up the loop the faction is named for: colony fills its warehouse, Heavy Freighter hauls to Earth, influence ticks up, repeat. Silicon is worth double iron at Earth, so weight your cargo toward it. Keep your deliveries steady rather than occasional — influence decays 1.5% per turn, so Sovereignty is won by a sustained trade rhythm, not one big load. And keep the Destroyer with the Heavy Freighter; losing it to a raider is the classic Guild disaster.
Playing against AMG
Watch the Earth Influence standings — the Guild wins quietly while everyone else fights. If its influence is climbing, you have three counters: out-deliver it (hard), beat it to 100 VP first (usually the answer), or disrupt the trade route itself — its heavy freighters are slow, fat, and precious. Remember that attacking costs your influence, so the VP race is the cleaner answer.
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 leads the three-to-five player tables (29–49%).
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 100 VP 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 41-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 18, Neptune 22, Makemake 27), plus most of its water: 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 genuinely competitive at small and mid tables (49% duels, 38% at three players).
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 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 toward the pack in big games (~13%): 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 0.85) 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: strong in duels (71%), ordinary in crowds.
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 (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, spot trades, missions, and proposed trades (U) — FTU buys ore cheaper and sells it dearer than anyone.
- 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.
- The best all-round measured performance: above the balance line at every table size, from 72% duels to 18% at a full table.
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
Like the Guild, the Traders win on the influence track while others brawl — but faster, because of the rate bonus. 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 Asteroid Mining Guild. Feel how one game is a sprint and the other wants a crowd it doesn't have.
- As UDF in a sandbox (0 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 41-VP pool is nearly half of a 100-VP win.
