''This page is part of the [[TI Space Nations]] mod.''

In vanilla Terra Invicta the [[Aliens|aliens]] rarely attack anything inside Jupiter's orbit. [[TI Space Nations]] makes them react to humanity spreading into space: founding nations angers them, and a faction they hate enough is hunted everywhere. Each part has its own setting and can be switched off.

== Alien hate from space nations ==
Founding a space nation provokes the aliens once, and holding it keeps angering them every month.

{| class="wikitable"
! Nation !! When founded !! Every month (to its executive faction)
|-
| Colony nation || +100 || +2
|-
| Planetary union || +150 || +5
|-
| United Nations || +200 || +5
|}
* The one-time gain uses the vanilla rules: ±20 % random, × 0.6 while the aliens are still quiet, capped by the difficulty. The aliens' proxy and appeaser factions resent it too.
* For comparison: vanilla alien hate decays by about 0.8 per month, war starts at 50 and total war at 200. A '''second colony nation''' can already push a faction to the total-war line.
* AI factions pay the same.

== Hunted factions ==
''Setting: Aliens hunt their enemies everywhere (total war or hate 200+)''

A faction is '''hunted''' as soon as the aliens declare total war on it, '''or''' its alien hate reaches '''200''' without an alien truce - on every difficulty and in every year. The aliens' proxy and appeaser and strongly pro-alien factions are never hunted.

For a hunted faction:
* all of its habs and fleets count as intruders everywhere - also at Mercury, Mars, Luna and in Earth orbit - and destroying them no longer reduces the aliens' anger;
* the alien war planner keeps all its attacks on every difficulty, plus '''2 extra attacks''', and only calls attacks off below half the war threshold;
* alien attack fleets may be up to '''1.5 ×''' larger;
* alien hate never falls below 200 - the hunt does not end by itself.
On Easy, alien hate stays capped near 70 until year 25.

=== Combined strikes ===
Against a hunted faction the aliens launch '''combined strikes''': up to 8 free alien fleets from one staging system join for one attack.
* '''Strength needed:''' the vanilla estimate of the target's defense × (1.25 + 0.25 per AU of distance, at most 3), and never less than 4 typical alien ships. Against bases they also bring 1.5 × the bombardment strength.
* '''Targets:''' the faction's habs (higher tier, cities, colony worlds of hunted nations and defended habs score higher; distance lowers the score) and its fleets of 3 or more ships that are parked at a world without an own hab, outside the Earth system.
* At most '''3 strikes''' at a time and '''2 new ones per month''', never two on the same world, preferably in different systems.
* A strike that is not ready after 45 days is called off, as is one that cannot catch its target fleet within 45 days.
* When the hunt is on, a base the aliens raze is taken over by them.

== Alien war production ==
''Setting: Aliens mobilize once loud…'' - the full level also needs the hunt setting.

The aliens get '''no extra income and no cheaper ships'''; only vanilla's brakes on their build-up are loosened.

{| class="wikitable"
! Lever !! Level 1 (aliens are loud) !! Level 2 (loud and hunting)
|-
| Idle shipyards build ships || half of the yards, 1 ship per day || all yards, 3 ships per day
|-
| Saving rule for warship upkeep || vanilla || relaxed: keep 15 % of a year's upkeep and 10 % of propellant, 180 days of reserves
|-
| War reserves || - || up to 3 shipyard systems, together as strong as the strongest hunted navy
|-
| Number of alien bases / outer-body limit / delay for the middle system || +2 / +1 / −1 year || +6 / +2 / no delay
|-
| Forward bases || - || at most 2 at a time, within 1 AU of systems with hunted habs inside Jupiter's orbit
|}

{{icon|warning}} Before removing the mod from a campaign, turn this setting off and play one month, so the war reserves are retired.

== Invasions of colony nations ==
''Setting: Aliens invade colony nations (spares pro-alien controlled ones)''

Once the aliens are loud, they can open up to '''2 invasion fronts''' against colony worlds, one per world. Each front is a vanilla Earth-style invasion aimed at a colony world.
* A front needs a reason: the invasion of Earth is under way, or a hunted faction holds the executive or a control point of a colony nation there. Such nations are 3 × more likely targets, undefended nations 2 ×.
* '''Spared:''' nations run by pro-alien factions (majority control or executive, for example Protectorate or Servants), alien-run nations, regions with space defenses or an existing landing, and unclaimed land.
* Alien fleets in Earth orbit still only land on Earth.

== Aliens and space nations ==
* The aliens never found, unify, settle or grow space nations.
* A nation whose executive is the aliens loses its Living Space and Frontier Settlement priorities.
* If the aliens hold only some control points, the human controllers pay for and grow the nation alone.
* Pro-alien AI factions value space nations 3 × as mission targets.

== The Servants' victory ==
The Servants' victory condition gets an extra requirement: ''Every space nation must be under the majority control of a pro-alien faction (met when no space nation exists).'' Nations controlled by the aliens themselves count as pro-alien.
