TI Space Nations/Colony Worlds and Cities

This page is part of the TI Space Nations mod.

Colony worlds

A colony world is a planet or moon that allows tier-4 habs and has at least 4 hab sites. Only these 29 worlds can have cities and colony nations. Each hab site is the core of one region of the world, and each region is divided into provinces.

World	Hab sites	Provinces per site	Provinces in total
Mars	25	4	100
Ganymede, Callisto, Titan	16 each	4	64 each
Luna, Io, Europa, Triton, Pluto, Eris	9 each	6	54 each
Mercury	8	7	56
Ceres, Tethys, Dione, Rhea, Iapetus, Titania, Oberon, Umbriel, Ariel, Charon, Quaoar, Makemake, Haumea, Orcus, Salacia, Achlys, Máni, Gonggong	4 each	10	40 each

In total there are 1,392 provinces and 207 possible colony nations.

Not colony worlds: Enceladus and Vesta (only 2 hab sites), Phobos and Deimos (tier-3 limit), Lagrange points and orbital stations (stations stay at tier 3).

On colony worlds the body panel and the hab screen show tier 4 as the maximum (This space body is large enough to support up to Tier 4 habitats.).

The possible colony nations are named after their hab site, for example Arcadia Planitia Colony (Mars), Kraken Mare Colony (Titan) or Shackleton Crater Colony (Luna).

Cities

A city is a surface base on a colony world whose City Core is finished (and not destroyed). The City Core makes the base a tier-4 hab, which unlocks the other tier-4 modules. A city with enough crew can declare a nation.

Tier-4 modules

Each tier-4 module is an upgrade of a vanilla tier-3 module (see Hab Module List). They can only be built in bases on colony worlds.

Module	Upgrades from	Research	Crew	Power	Build time	Mass	Effect	Monthly upkeep
City Core (one per hab)	Colony Core	City Core project	1,000	0	180 days	1,600 t	Makes the base a tier-4 city. Mission control −6.	40 , 1 , 1
Arcology	Civilian Complex	Arcology project	5,000	−240	240 days	4,800 t	+90 , +25 , stability 20	2 , 20 , 12 , 4
Colonial Administration (one per hab)	Administration Complex	Colonial Administration project	2,000	−240	300 days	2,400 t	+45 control point capacity, mission control +4, efficiency 0.15	140 , 16 , 1 , 1 , 1

For comparison, the tier-3 modules they replace: Colony Core 125 crew, mission control −4 · Civilian Complex 2,500 crew, +40 money, +10 influence, stability 12 · Administration Complex 1,000 crew, +30 control point capacity, mission control +2, efficiency 0.1 · Marine Battalion Barracks 750 crew, +12 ops, marines 40 · Agriculture Complex 25 crew, farm 3,000.

The research projects are listed on Technologies and Projects.

Rules

• The City Core needs a tier-3 base. All other tier-4 modules need a City Core.
• Modules that are limited to one per hab stay limited: a hab with a Colonial Administration cannot have a second Administration chain. Arcologies can be built several times.
• The aliens never build city modules. AI factions build them only while the setting AI declares colony nations and pursues whole worlds is on - see AI.
• A destroyed tier-4 module leaves a Destroyed Module ruin like a tier-3 module.
• Crew for a nation: a City Core (1,000) and two Arcologies (2 × 5,000) give 11,000 crew - enough for the default threshold of 10,000.
