== Colony worlds ==
A '''colony world''' is a [[Celestial Bodies|planet or moon]] that allows tier-4 habs '''and''' has at least '''4 [[Hab Site List|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.

|}
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 [[TI Space Nations/Colony Nations|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.

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 [[TI Space Nations/Technologies and Projects|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 [[TI Space Nations/AI|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.
