AI Brains

AI Brains

The AI button on the war setup screen chooses which AI runs your enemies and which runs your allies, per race. Its text reads: "TITANS: base game AI / QUELLER: greater challenge at the cost of performance / PENCHANT: increased personality / An AI that does not know a race is not offered for it." The table has one row per installed race and two columns, Opponent and Ally. From the next release it has a third column, Co-op, and the text adds "CO-OP: the AI players a host adds to a co-op session".

Brain	Races it knows	Character
Titans	Every race	The base game's AI, following the faction's unit mix and the commander's personality
Queller	MLA and Legion	A harder AI that costs more processing. It fights with the faction's preferred arm and has its own behaviour in an FFA
Penchant	MLA only	The base game's AI given a distinct flavour on top of its personality

Opponent is the brain your enemy factions use. Ally is the brain your Sub Commanders and any allied Commander use. You can pick different brains for each, and different brains for each race.

Co-op, from the next release, is the brain the host's AI players use. Until you pick one, it follows the Opponent brain.

Queller

Queller does not use the faction production shares on Factions. Instead it takes the faction's arm: Legonis Machina tanks, Foundation air, Synchronous bots, Revenants orbital, and Cluster land. In an FFA system it switches to its FFA behaviour. Ten personalities never appear under Queller: the eight faction specialists (Armor, Roboticist, Air Force, Navy, Grunt, Dragoon, Space Invader, and Astronaut) plus Fabber and Swarm. Sub Commander Fabber Tech is never offered while your Sub Commanders use Queller.

Penchant

Penchant is the Titans brain with a flavour added, shown after the personality name in Planetary Intelligence and on the Sub Commander card. A flavour adds extra units to what the personality builds, so an "Aggressive Artillery" commander attacks early and also builds artillery.

Flavour	Favoured units
Vanilla	None: the personality alone
Artillery	Pelter, Lob, Holkins, Catapult, and Unit Cannon
Fortress	Single Laser Defense Tower, Laser Defense Tower, Advanced Laser Defense Tower, Galata Turret, Flak Cannon, Torpedo Launcher, Advanced Torpedo Launcher, Umbrella, Anti-Nuke Launcher, Pelter, Lob, and Catapult, plus everything Minelayer builds
All-terrain	Dox, Slammer, Locusts, Drifter, and Kaiju
Assault	Ant, Leveler, Dox, Slammer, Kestrel, Orca, Barracuda, Leviathan, and Kraken
Boomer	Boom and Locusts
Heavy	Inferno, Vanguard, Slammer, Spark, Mend, Wyrm, Horsefly, Angel, Orca, Leviathan, and Barnacle
Infernodier	Grenadier, Gil-E, Bluehawk, Spark, Inferno, Vanguard, and Sheller
Raider	Stryker, Dox, Slammer, Boom, Locusts, Kestrel, Piranha, Kraken, and Typhoon
Sniper	Grenadier, Gil-E, Bluehawk, Sheller, Drifter, Hornet, Orca, and Leviathan
Nuker	Nuclear Missile Launcher
Tactical	Catapult, Flak Cannon, Bluehawk, Hornet, and Stingray
Platoon	No favoured units: it attacks in smaller numbers of larger armies
Minelayer	Land Mine and Stitch

Personalities

Every enemy commander and Sub Commander has a personality, shown in Planetary Intelligence. In the descriptions below, "advanced tech" is the point where the AI starts building advanced factories, and "self-assessment" is how it rates its own army against yours before attacking. An AI that overestimates itself attacks sooner and with less.

Specialists (Titans and Penchant only)

Personality	Faction	Behaviour
Armor	Legonis Machina	Builds almost only vehicles
Roboticist	Legonis Machina	Builds almost only bots
Air Force	Foundation	Builds almost only air
Navy	Foundation	Builds almost only naval
Grunt	Synchronous	Builds almost only bots
Dragoon	Synchronous	Mostly air, with the rest in bots
Space Invader	Revenants	Builds only orbital
Astronaut	Revenants	Half air and half orbital

Generic personalities

Personality	Behaviour
Baseline	The faction's own unit mix, unmodified
Original	The personality the base game's Galactic War gave that faction
Boss	The faction boss: two fabbers per factory at both tiers, three times the fabbers when alone on a planet, and at least four basic and one advanced fabber
Uber	The personality behind Queller's top difficulty. Spends a little more freely, two advanced fabbers per factory, three times the fabbers when alone on a planet
Absurd	The personality behind the base game's top difficulty. Reaches advanced tech a little later, with at least two basic and three advanced fabbers
Fabber	Two fabbers per factory at both tiers and far fewer factories when alone on a planet. Not used by Queller
Defender	Reacts sooner to running out of resources but tolerates unmet demand. At least four basic fabbers
Luddite	Reaches advanced tech three times later than normal, twice as late when alone on a planet
Technologist	Reaches advanced tech twice as early, three basic fabbers per factory, at least four basic and one advanced fabber
Cautious	Underestimates its own strength, so it attacks only with a clear advantage. At least four basic fabbers
Aggressive	Overestimates its own strength by double, so it attacks early and often. At least two basic and one advanced fabber
Rush	Overestimates its strength by half and reaches advanced tech twice as late
Turtle	Rarely attacks, reaches advanced tech twice as early, three fabbers per factory at both tiers, and allows up to eight basic and six advanced fabbers. It defends and techs
Factory	Half a fabber per factory and almost ignores resource demand, so it builds factories over fabbers and keeps spending
Swarm	Ten basic factories for every advanced one and three advanced fabbers per factory: an endless stream of basic units. Not used by Queller
Economist	Reacts sooner to running out of resources and almost ignores unmet demand. At least four basic fabbers
Random	Drawn each war from the faction's other personalities

The Cluster faction's Workers and Security use the generic personalities only. The Guardians on the treasure planet have the personality "Unknown".

Modifiers

Difficulty tiers apply a personality modifier on top: Slower Expansion on Beginner, Casual, and Iron, and Prevent Waste on Platinum, Diamond, and Uber. A Custom war can pick its own (see Difficulty).
