Once a technology has been fully researched, it unlocks new base facilities or unit improvements. Bases are the cornerstone of a Faction.
Analogous to Cities in Civilization, they build units, collect resources, can be captured or destroyed. Bases are built from units equipped with a Colony Pod and can be built, with few restrictions, on both land and water.
Its primary elements are its resource squares, Citizens and Production Queue. A base collects resources from the surrounding resource squares by assigning one Citizen to a square.
Thus the more Citizens a base has, the more squares it can work and the more resources it can gather.
Each square can produce three types of resources, Nutrients, Minerals and Energy, and may be improved to increase its yield.
Nutrients support the existing Citizens each Citizen deducts two units of harvested Nutrients ; any surplus at the end of each turn is added to existing stockpile, and once you have enough, an additional citizen is made.
If you have a shortfall, then citizens will begin leaving. Minerals are used to build Units, Facilities and Secret Projects.
The more minerals a base harvests, the fewer turns it takes to complete its production. A base can support between zero and four units for free, depending on social engineering.
Beyond the free support limit, each unit requires mineral support and will use up one or two minerals of production from its home Base, depending on social engineering.
Energy is used to maintain base facilities once they are built. Any surplus energy is automatically converted into any combination of Psych points, Lab points and Energy credits, depending on your Social Engineering settings to where the excess goes to.
Lab points feed into the faction's accumulated technology research. The more lab points are generated, the faster new technologies are discovered.
Energy credits are banked and can be spent to hurry a Base's production item, upgrade military units or fund their activities, or as currency to trade with other factions.
Each citizen of a Base is one of three types: Worker, Drone, or Talent. In the beginning, everyone is a Worker. If the workers become unhappy, they turn into a Drone, and this can cause drone riots.
To keep them happy you can build certain base facilities, put more of your surplus energy into "psych" in the social settings menu, switch some workers to Talents, build certain Secret Projects to help, or use as many police units as your social settings allow.
You can also nerve staple them, with some consequences. Some talents give you more psych bonuses than others. As the base population grows very large, there may be no empty squares for Workers to use, but as Talents the citizens can still contribute research and wealth.
Workers and Drones harvest resources from the surrounding squares. Talents stay within the base and do not harvest raw materials energy, nutrients, minerals ; instead they directly produce Economy, Labs and Psych in varying amounts depending on the type of Talent.
More advanced Talent types are unlocked by Tech progress. At first Doctors are available, which produce two Psych each.
It costs two Psych to convert one Worker to a Talent, so you need the same number of Doctors as you have Drones.
Once a base reaches a certain size, determined by the difficulty level, number of bases, social engineering choices and base facilities, each new citizen is a Drone.
During a Drone Riot no one does any work, and facilities can be destroyed, and if it goes on long enough, the entire base can revolt and join another faction.
Drone Riots are ended either by creating an adequate number of Talents, by reducing the number of Drones using police or base facilities, or by nerve stapling.
New citizens spawn when a base accumulates excess nutrients. The amount of nutrients needed to create growth becomes higher as the population multiplies.
Social engineering choices or facilities can help reduce this required amount during each stage of growth. If the base's population reaches i.
Lab points from all bases are "banked" at the end of each turn. When the accumulated points reaches a threshold set by the current technology being research, the technology is discovered.
A Base can build units, facilities and secret projects. Facilities, analogous Buildings in Civilization , improve some aspect of the base it is built in: Secret Projects, comparable to the Great Wonders in Civilization, confer faction-wide benefits but are expensive and can only be built once; once built, no other faction may build it and if destroyed it cannot be rebuilt.
A unit is made up from different components such as chassis, weapon, armor, reactor, and special ability slots. Unlike the Civilization series proper, units come in default designs but can also be customized by the player.
As new technologies become available, old designs may be brought up to date and existing units upgraded.
Generally, only friendly units the player's own or those of a pact ally can occupy the same square. Enemy units must be eliminated or, in some cases, forced to withdraw in order to move into their square.
Many factors affect the outcome of combat, including:. Researching certain new technologies unlocks progressively better equipment. Possessing certain support infrastructure such as Command Centers , creating units with certain special abilities such as High Morale , and having a positive morale rating in social engineering will all confer morale bonuses to new units, effectively enhancing their strength multiplier; conversely, a negative morale rating will incur morale penalties on new units.
Also, gaining access to the mysterious alien monoliths that dot the planet, or defeating enough enemies to gain experience, will upgrade an existing unit's morale.
Psionic combat ignores conventional components and circumstances, focusing instead on morale, and gives a bonus to the attacker if the combat takes place on land.
It is resolved normally. Native life forms fight psionically, and some components enhance a unit's psionic ability or permit it to make psionic attacks.
It is also possible to cultivate native life forms under a player's control. Here the equivalent of morale is determined by ecological status and breeding techniques, rather than infrastructure.
Psi combat also takes priority over regular combat, so that if either attacker or defender is psi-capable then psi combat occurs in place of regular combat.
Attacks that occur from a distance, such as missile strikes and artillery or naval bombardments, are an exception to this priority.
There are a number of different unit types on land, sea and air, each with specific special properties and movement speeds.
Air units are not initially available and require considerable technical development. Conventional missiles are a special type of single-use unit.
Planetbuster missiles blast holes in continents, but provoke extreme global warming , a frenzied assault from native life, and causing all other human factions to declare vendetta upon you.
The Datalinks, similar to Civilization' s Civilopedia, contain information crucial to playing the game. Most important is the tech tree, which shows a complete system of all technologies available in the game, along with prerequisite technologies and all benefits the technology gives new chassis, weapon, armor, reactor, or special ability types, along with new terraformer abilities, base facilities and secret projects, bonuses to xenofungus squares, social engineering choices, etc.
In all technology trades the game allows consulting the Datalinks to find exactly what is being offered or demanded.
In addition, the Datalinks store the quotes involved with all technologies and secret projects. Many Alpha Centauri fans enjoy the quotes in particular and the thought behind them.
The game's creators developed the personality and ideology of all the faction leaders through these quotes, as well as thoughts on human psychology.
For instance, the Virtual World secret project is accompanied by Chairman Yang's view that reality is only what one perceives it to be, while Provost Zakharov denounces the general simplistic views on genetics when such technologies are discovered.
The game is represented on an isometric map of the planet surface, upon which bases are built and units deployed.
Over centuries, this causes their apparent positions to slowly change. Most assumed that the stars are immortal and permanently fixed on the celestial sphere , as stated in the works of the philosopher Aristotle.
Thomas Henderson in the s at the Royal Observatory at the Cape of Good Hope discovered the true distance to Alpha Centauri by analysing his many astrometric mural circle observations.
The velocity in the western direction is Using spectroscopy the mean radial velocity has been determined to be around Other conjunctions will also occur in the coming decades, allowing accurate measurement of proper motions and possibly giving information on planets.
As the stars of Alpha Centauri move closer to the Solar System, their measured proper motions , trigonometric parallaxes and radial velocities slowly increase.
For example, in the apparent size of the semi-major axis of the orbital ellipse will increase by 0. Based on the system's common known proper motion and radial velocities, Alpha Centauri will continue to change its position in the sky significantly and will gradually brighten.
For example, in about 6, AD, Alpha Centauri's true motion will cause an extremely rare first-magnitude stellar conjunction with Beta Centauri , forming a brilliant optical double star in the southern sky.
It will then pass just north of the Southern Cross or Crux , before moving northwest and up towards the present celestial equator and away from the galactic plane.
In August , the European Southern Observatory announced the discovery of a planet slightly larger than the Earth orbiting Proxima Centauri.
In , a planet around Alpha Centauri B was announced, but in a new analysis concluded that it almost certainly does not exist and was just a spurious artefact of the data analysis.
The existence of a planet, Alpha Centauri Bc, was announced in This planet would most likely orbit Alpha Centauri B with an orbital period of The median of the likely orbits is Its orbit would likely have an eccentricity of 0.
Like the probably spurious Alpha Centauri Bb, it likely has lakes of molten lava and would be far too close to Alpha Centauri B to harbour life.
Because both the principal stars are fairly similar to the Sun for example, in age and metallicity , astronomers have been especially interested in making detailed searches for planets in the Alpha Centauri system.
In , computer simulations showed that a planet might have been able to form near the inner edge of Alpha Centauri B's habitable zone, which extends from 0.
Certain special assumptions, such as considering that Alpha Centauri A and B may have initially formed with a wider separation and later moved closer to each other as might be possible if they formed in a dense star cluster would permit an accretion-friendly environment farther from the star.
In addition, the lack of any brown dwarfs or gas giants in close orbits around A or B make the likelihood of terrestrial planets greater than otherwise.
Here, the comets provided the inner planets with their own source of water and various other ices. The sky from Alpha Centauri would appear much as it does from the Earth, except that Centaurus would be missing its brightest star.
Procyon would be displaced into the middle of Gemini , outshining Pollux , whereas both Vega and Altair would be shifted northwestward relative to Deneb , giving the Summer Triangle a more equilateral appearance.
Depending on the binary's orbital position, the binary stars would be resolvable to the naked eye, but occasionally and briefly, as a single unresolved single star.
Rigil Kent is short for Rigil Kentaurus ,  which is sometimes further abbreviated to Rigil or Rigel , though that is ambiguous with Beta Orionis , which is also called Rigel.
To the Australian aboriginal Boorong people of northwestern Victoria , Alpha and Beta Centauri are Bermbermgle ,  two brothers noted for their courage and destructiveness, who speared and killed Tchingal "The Emu" the Coalsack Nebula.
Alpha Centauri is a likely first target for manned or unmanned interstellar exploration. Using current spacecraft technologies, crossing the distance between the Sun and Alpha Centauri would take several millennia, though the possibility of nuclear pulse propulsion or laser light sail technology, as considered in the Breakthrough Starshot program, could reduce the journey time to decades.
Breakthrough Starshot is a proof-of-concept initiative to send a fleet of ultra-fast light-driven nanocraft to explore the Alpha Centauri system, which could pave the way for a first launch within the next generation.
An objective of the mission would be to make a fly-by of, and possibly photograph, planets that might exist in the system.
This upgrade will greatly increase the likelihood of planet detection in the system. From Wikipedia, the free encyclopedia. For "a Centauri", see HD For "A Centauri", see A Centauri.
