Ethereal Invasion (Area 51 Expansion Pack)-ver1.65

Alien invasion begins later in the game through Barbarian and Free City. This adds a menacing late game crysis.



When the first XCOM squad units were added to the Civilization 5 Brave New World, we began to dream of an 'alien invasion'. And that dream gradually materialized with the addition of an alien faction in the Red Death scenario. But Firaxis is not working, so it's time for us to move on our own.

This mod is compatible with the Area 51 wonder mod, allowing for a very lethal alien invasion late in the game. Panic levels all over the world are skyrocketing, and if you are not prepared, all civilizations will be destroyed by invaders with mind control abilities. Or maybe you could use this invasion in a useful way.

Systematically, this only makes minor changes to JNR's Area 51 alien units set up as Wonder-only units. But the consequences are very fatal.

0. Added Civilopedia
"Adds Civilopedia of Area 51 and alien units left blank by JNR based on historical context and XCOM canon."


1. The Alien Infiltrator becomes the barbarian's recon unit.
Appears on the map when someone researches satellite technology
Esasically, they get a Hive Mind bonus even if they don't have a U.F.O. (You know this needs no explanation, right?)

2.Capture aliens and extract knowledge from them or confuse your enemies.
The following two features are added to Alien Infiltrators:
- Use them like engineers to support your Spaceport and Campus districts.
- Can build barbarian camp improvement.


3. Upon arrival in future Era, an all-out alien invasion begins!
Barbarian U.F.Os appear on the map when someone researches Offworld mission technology.
the moment the barbarian U.F.O appears on the map -5 Loyalty to Every city in a whole civilization

4. Witness the advent of THE ADVENT.
U.F.O and Alien Infiltrator will spawn in Free City that has left due to lack of loyalty.(After Satellite technology)

All these changes will be visible when you activate the Barbarian Clan Mode. You can 'consider' the elder chosen as the new leader of the barbarians and use it as a force, or you can induce their aggression.

before that, you'll have to prepare for the massive psionic mind control that takes place around the world and the rebellion that ensus.



This mod will be added with updates and add-on mods. The ultimate goal is to implement XCOM into CIV 6.

* New Secret Society: The Bureau
"Designed around MIB and conspiracy theories, this secret society grants players allegiance to their own country, control of the barbarians, and new capabilities for the Recon Class."
(The function under consideration at this time is immediately revived in the dedicated Improvement when the Recon class unit dies)
