Base

From Alpha Centauri Wiki
Jump to: navigation, search

Bases are the cornerstone of your faction in Alpha Centauri. These manufacture your units, collect your energy for your economy and research, provide votes for planetary governor and supreme leader, and provide some defensive assistance. If playing with Do Or Die, taking all of a faction's basses results in game over for that faction. It is through your bases that everything your faction does gets implemented. Conquering a base has important effects.

Contents

Base Screen Overview

Most base management is done through the Base screen. This can be accessed by right clicking on a base and clicking on "Goto Base Screen." At the top are #Governor Settings. Down the left side are the nutrient tanks for #Growth, the commerce that your base is doing, and a box containing the mission year, your faction's energy reserves, and this base's #Eco Damage. The right side contains a list of #Base Facilities and #Secret Projects this base has produced. In the center is a screen where you can see this base's #Resource Production, #Support map, or #psych effects. Bellow this map are details of this base's #Budget.

At the bottom left is information on and controlls for this base's #Base Production. In the middle bottom is the name of this base, the #Citizens of the base and the list of Units occupying the base square. At the bottom right is a list of units supported by this base. By clicking the arrows next to the base name, one can jump to the base screen of other bases in your faction.

Citizens

At the bottom of the base screen is a list of citizens that live in the base. Each citizen is listed as an icon and has particular effects. There are various ways to lower the number of drones at a base or increase the number or talents.

  • Workers: are rendered yellow and are the working class of a base. These citizens can #work a square in the base's grid and contribute no special benefits or penalties.
  • Talents: are rendered blue and are the citizens of your base who for one reason or another have an abundance of leisure. These citizens can #work a square in the base's grid. Having more of these citizens than drones prevents a drone riot and having most of the citizens (including specialists) of a base these citizens and having no drones produces a golden age at the base.
  • Drones: are rendered red and are downtrodden citizens (for one reason or another). If there are any of these at a base, it prevents a golden age at the base and if there are more of these than talents in a base, the base experiences a drone riot. There are multiple ways for drones to be created:
    • Dependent on Difficulty every new citizen after a certain number at a base is initially rendered as a drone.
    • Dependent on Difficulty and a faction's Efficiency rating, once a faction controls a certain number of basses, each new base controlled adds a drone randomly at one base.
    • As a result of conquering a base, that base will have additional drones for the next 50 years. The number of extra drones is the minimum of either 5 minus 1/10 times the number of years since the conquest or the sum of base size and difficulty level minus 2 all over 4 and rounded up. <math>\min \left ( \left \{ \left ( 5 - 1 \over 10 \right ) * t , \frac {BaseSize + Difficulty - 2} {4} \rihgt \} \right )</math>.
    • For pacifism resulting form a low Police rating.

Talents and Drones can also be created as the result of Faction effects.

In addition to these citizens, you can create Specialists at your bases. These citizens no not work base squares and thus don't contribute to nutrients, minerals, or pre-budget base energy. This means that they need other citizens to feed them and they won't help the base build things. What they do is that they is they add energy at this base to the different energy allocations at the end of the #budget. When there are no base squares a citizen can work, any new citizen must be a specialist. They do impact the calculation for whether a base is in a golden age. Because of this, a golden age is imposable a base that has more than 40 population even if it has 20 talents and 21 transcendi.

To create a specialist, left click on a citizen and assign it to a particular specialty. To change a citizen's specialty or to turn it into a worker, do the same. Any citizen can be a specialist and turning all citizens into specialists can prevent any of them from being drones but could cause a crash in base production, mass starvation, and stranding units (causing them to disband).

There are several specialists who become more special with advancing technology. Once a specialist replaces a particular specialists the more ordinary specialist is no longer available.

Psych

Psych is a measure of how devoted a base is to making its citizens happy. A base that invests in psych should have few to no drones and several to many talents. Through different processes a base's energy, nutrient, or mineral output can be invested in psych. Energy can be spent on psych by a faction's factionwide budget, nutrients can be spent to support psych generating specialists, and minerals can create #Base Facilities, #Secret Projects, and Police units.

By clicking on the "psych" tab on the base screen one can view the psych effects on the citizens of the base. These effects are calculated in a specific order and is given bellow.

  1. First the base calculates its base citizenry. The non specialists start as workers and are changed into drones and talents per the above descriptions. The total population in a base (including specialists) are included in this calculation and faction effects come last.
  2. Second the base changes workers into talents based on this base's #psych spending. The final spending from the #budget and the input from specialists is included here. 2 energy spent on psych changes a worker into a talent. If there are no more wokers than 2 energy spent on psych changes a drone into a worker (with 4 changing a drone into a talent).
  3. Third the base includes the effects of #Base Facilities. These mostly change drones into workers but they can also change citizens into talents or drones depending on the facility.
  4. Fourth the base includes the effects of Police. Ordinarily one or more combat units (up to the maximum allowed for your faction) acts as police with each police unit turning one drone into a worker. A high police rating can see a police unit turning another drone into a worker, and Non-Lethal Methods can turn another drone into a worker.
  5. Fifth the base includes the effects of pacifism from low Police ratings and having combat units outside your faction's territory. Note that a faction cannot have both police and pacifism at the same time.
  6. Sixth the base includes the effects of #Secret Projects. These effects are the same factionwide and not limited to a particular base.
  7. Seventh the base turns all talents and drones into workers if your base has built a Punishment Sphere.

The result after these calculations are the base's population composition. Specialists are not effected.

Drone Riots

If a base has more Drones than Talents then it will be in a state of a Drone Riot. While a base is experiencing a drone riot, the workers still work base squares but all #Minerals after supporting units are lost. #Energy and #Nutrients are collected and used as normal and maintenance is still payed on facilities. The base operates normally except production is stopped. This can make it harder to manage drones as one cannot build more police or facilities to help manage them. The exception is that one can switch production to a unit or facility that has 0 or negative turns to complete (after the mineral penalty when switching #Base Production there are sufficient minerals to complete the item).

If a drone riot continues, the riot can destroy #Base Facilities. This can destroy facilities that will make the riot worse (e.g. the rec. commons) by increasing the difference between drones and talents and making it a larger task to bring the base under control. If a base that is rioting for long enough and if the faction has a Police rating of less than -2, the base can defect to a rival faction. The faction that is chosen is likely to be the Drones or one whose leader has a poor impression of you. This defection can happen after one turn. Drone riots do not destroy secret projects.

There are a few ways to handle a riot. One can increase the policing in a base. One can increase psych spending either factionwide or by turning citizens into specialists. One can commit an atrocity such as destroying the rioting base or nerve stapling its citizens. One can change production to a facility that shows negative time to complete on the Base Production grid that can help quell the riot (eg. the rec. commons) or to a colony pod to reduce population. One can build or gain control of a Secret Project that will quell or help with the riot.

Long term, base facilities should be built, police should be added, or factionwide effects should be changed to make a drone riot harder to happen at this base.

The The Telepathic Matrix prevents drone riots at all basses belonging to the controlling faction no matter the difference between the number of drones and talents at a base and ends any riots that are currently ongoing.

Golden Age

If a base has no drones, at-least half of its population are talents, and has a base population of at-least 3, it is in a golden age. Golden ages are determined base by base and while unlikely, it is possible for a faction to have 1/3 of its bases in a golden age and 1/3 in drone riots. While a base is in a golden age, that particular base is considered to have the social effects of +2 growth and +1 economy over what your faction would otherwise provide for that base.

Resource Production

Your workers, talents, and drones work base squares. There are twenty squares surrounding a base which can be worked by these workers. A worker that works one of these squares collects nutrients, energy, and minerals from the square dependent on the underlying terrain, Terraforming, and technology. The square the base is in also provides resources and never has anyone work it. Faction benefits, social engineering, base facilities, and secret projects determine the productivity of this base square.

The squares workers at a base can work are called that base's grid and are visible when one clicks the "resouce" tab in the base screen. It is possible for the base rid of two bases to overlap. If a worker at another (or this) base is working a square, no other worker from any base can work the same square. Squares worked by a worker at this base show the number of nutrients, minerals, and energy that worker is generating. Drones, Workers, and Talents all collect resources with equal efficiency.

Everything that is collected goes into the #Base Budget

Base Budget

The base budget is given bellow the map. These two screens shows how all of the nutrients, minerals, and energy collected by a base's workers and at the base square are allocated and spent. These amounts can be changed and adjusted by moving workers around for different #Resource Production and changes in your faction's Social Engineering.

Nutrients

There are no nutrients lost during collection and distribution though each citizen (no matter the #type) eats two nutrients each turn. Any surplus is added to the base's nutrient tanks and any deficit is subtracted from the nutrient tanks effecting #Growth.

Minerals

There are no minerals lost during collecting and distribution though units may require support depending on the number of units call this base home and your faction's Social Engineering. The surplus is added to base production and any deficit results in supported units being disbanded. #Base Facilities increasing mineral production do so before the minerals are taken to support units.

Energy

Energy is lost during collection. The amount lost called loss to Inefficiency and is impacted by this base's distance from the faction headquarters and the faction's Efficiency rating. The amount of energy lost to inefficiency is given by Inefficiency = (Energy × Distance ÷ (64 - (4 - Efficiency) × 8)) or <math> \frac {Energy*Distance} {64 - 8 \left ( 4 - Efficiency \right ) } </math>. If a faction headquarters does not exist, Distance=16.

Distance is calculated by finding the shortest path from the base to the headquarters by moving along two diagonals (square to square by squares that share a vertices but not an edge). The distance is the number of squares moved in the longer diagonal plus half the number of squares moved in the shorter diagonal.

The ratios are given in this table. A base can never lose more to inefficiency than it collects in energy and there is never any inefficiency at a faction headquarters (regardless of any other effect).

Inefficiency Table
Efficiency Rating Percent Lost to Inefficiency
4 Distance/64
3 Distance/56
2 Distance/48
1 Distance/40
0 Distance/32
-1 Distance/24
-2 Distance/16
-3 Distance/8
-4 100%

The energy accumulated after inefficiency is taken into account is allocated to economy, labs, and psych according to your faction's social engineering. Bonuses given by #Base Facilities and some #Secret Projects then take effect. These bonuses stack additively for base facilities and geometrically for secret projects. For example two 50% bonuses to economy count as one 100% to economy and not a 125% bonus. Economy and Labs spending is covered in Faction Economy which economy enlarging your energy reserves and labs progressing in research. #Psych spending contributes to the well being of this base's citizens and is covered above.

Your #base's facilities (for the most part) require maintenance. At the beginning of a turn, each base in turn contributes its economy spending to the faction energy reserves. When all bases have contributed their energy, maintenance is payed out of energy reserves for base facilities. If there is not enough energy to maintain all facilities, a facility is randomly scraped (with your faction collecting the energy reserves to help pay maintenance at other bases) until your faction has enough energy to maintain its facilities.

Growth

The nutrient tanks in the upper left determine population growth. The surplus or deficit of #nutrient production gets added to or subtracted from the nutrient tanks. When the nutrient tanks are full a new citizen is produced (who immediately needs to eat. If, for example, population grew with one nutrient and the new citizen cannot produce new nutrients, it is not created and the nutrient tanks are emptied) and when nutrient tanks are empty and there is a nutrient deficit (whenever the tanks would go negative) a citizen is destroyed leaving the nutrient tanks empty for the next turn.

Population at a base cannot change by more than one from turn to turn due to these effects. The number of columns is 10 minus your factions Growth rating and the number of rows is 1 + the base's current population (the population the base will be at after growth). The exception is if a faction has a -3 growth rating. The base has nutrient tanks as if it had a -2 growth rating (12 columns) and the mechanics work the same except that if population growth were to occur everything happens the same except the base population number doesn't change.

A base that has built a Children’s Crèche is considered to belong to a faction that has a growth rating of 2 greater than what it is. If a faction is at a -3 rating, the base grows normally with 11 columns. If a faction has a -3 rating (but would have lower if allowed) then it grows normally with 12 columns or it stays at a -3 raiting. If a faction has a growth rating of 4 or more than it is in a population boom. For all other situations the base grows normally with 2 fewer columns in its nutrient tanks.

A faction (or base) that has a +6 Growth rating or controls The Cloning Vats is considered to be in a population boom. During a population boom, if a base produces a nutrient surplus of at-least 2, it adds one population. Bases with a growth rating of +6 have nutrient tanks of 5 columns (used to store food for leaner times). A base still does not grow by more than 1 population each turn from these mechanisms.

Support

A unit normally requires a unit of minerals to support. This value can be modified by the clean reactor ability or by a faction's social engineering. The base that is designated a unit's home base pays this mineral meaning that base has less than one mineral available for manufacturing. Pictures of the units supported by a base are at the bottom right of the base screen and clicking on a unit's picture activated that unit. A map of where all the units supported is available by clicking on the "support" tab. Orders can be given to a unit to change its home base to the one it is currently in.

Base Production

In the bottom left there is the base production controls. Any #Minerals collected that don't go to support units go towards this production. Units, #Base Facilities, #Secret Projects, and Stockpiling Energy can be produced. At the top of this box is an image of the thing being produced. In the middle is the mineral progress for the current production. At the bottom is the number of turns until the current production is finished.

The number of columns in the production for a thing is 10 minus the faction's Social Engineering#Industry rating and the number of rows is determined by what is being built. Unit costs are here while #Base Facility and #Secret Project costs are bellow. While Stockpiling Energy, the number of minerals going towards production is divided by 2 and rounded up. This amount gets added to your faction's energy reserves.

At the start of a turn the computer goes through each base and progresses production. If production finished during this check, the Unit or Facility is completed and the base moves on to the next item in the queue, what the governor decides, a repeat of the item it finished, or stockpile energy. The computer prioritizes this choice in that order. If less than one row of minerals is left after production, all of these minerals are applied to the new item under production. If more than one row of minerals is left after production, the new item under production has one row of minerals applied to it and half of what minerals above one row are left over. On Citizen or Specialist Difficulty, all of the minerals left over are applied to the next thing under production.

To the right of this box is the queue list, change, and hurry controls. Clicking hurry allows you to finished an item sooner. The hurry cost is different for different items and making a partial payment is possible. The costs are given in the table bellow. Hurrying an item won't immediately finish it but if all minerals are purchased for an item it will be produced at the start of the next turn. A partial payment gives the number of minerals to produce an item in proportion to the payment made to the cost to complete the item. These rules mean that it can be advantageous to make the smallest partial payment so that the item can be produced in one turn rather than completing it.

The minerals cited in this table are the number of minerals needed to complete the item.

Hurry Costs
Item Cost to make a full payment. Adjustments
Unit 2 times the number of minerals plus the number of minerals squared divided by 20. Rounded down
Base Facility 2 times the number of minerals Doubled if less than 10 minerals already filled
Secret Project 4 times the number of minerals Doubled if less that 4 mineral rows already filled.

One can change the object being produced. On Citizen and Specialist Difficulty no minerals are lost from changing production but on higher difficulty, half of the minerals more than the first row of production are lost. This can hit twice if one changes what a governor starts to produce after another item has finished production. Switching from a Secret Project to another Secret Project does not lose minerals but switching from a Secret Project to something else does. Clicking on change brings up the production screen for the base. The screen is arranged in a grid with the units at the top, base facilities in the middle, and secret projects at the bottom. The number of turns listed are the number of turns until the base finishes that item given the current mineral investment (while considering the losses from switching). Clicking on an item switches production to that item. If you want to build a unit that is not available click on "workshop" to bring up the Design Workshop.

Clicking on the "queue" button brings up the queue controls. This brings up the base's production grid which is the same as if one were to change production except the turns are the number of turns to finish the production from 0 minerals at the base's current mineral production. Clicking on "workshop" brings up the Design Workshop, "delete" removes the currently selected item from the queue list, "replace" replaces the currently selected item in queue list with the currently selected item in the production grid, "insert" puts the currently selected item in the production grid in the currently selected slot in the queue list moving all items currently in the queue list in the currently selected position and bellow down, "cancel" leaves the queue list reverting it to what it was when you clicked on the "queue button," and "ok" leave the queue list as it currently stands.

Eco Damage

Mineral production and terrifying in a base's grid increase a base's "Eco Damage." The higher a base's eco damage the more likely it will cause fungus to grow during the aliens turn and the greater chance this growth releases multiple native lifeforms. The sum total of all eco damage at all basses contributes to a total number for the planet. Once this number surpasses a certain number, the sea level will start to rise. The game will inform you of how much higher the sea level will be in 20 years given the current impact. During this 20 years there will be occasions where all land tiles have a number subtracted from their altitude possibly turning land tiles into water tiles. Ocean tiles will also become deeper during these events. These events can destroy land bases that don't have a Pressure Dome. Volcanoes can also randomly erupt on Planet based on this sum total of eco damage.

The eco damage at a base is complicated to calculate and one should note that the description given in the datalinks is incomplete. Generally speaking the more terraforming exists in a base's grid and the more minerals are being produced at a base, the more eco damage occurs and the more forest and fungus squares in a base's grid, the less eco damage occurs. There are #Base Facilities and #Secret Projects that decrease eco damage (as well as some that indirectly increase it).

For specifically there are a number of factors that impact eco damage:

  • Atrocities: The number of atrocities your faction has (ever) committed while the UN charter is in effect not counting nerve stapling and fungal payloads.
  • Mitigators: The number of the following at this base: Centauri Preserve, Temple of Planet, Nanoreplicator plus the number of the following a faction controls: The Pholus Mutagen, The Singularity Inductor.
  • Minerals: Total minerals produced by this base (after mineral bonuses) minus the number of minerals this base receives from space.
  • Terraforming: (for all squares in a base's grid). 2 times the number of worked improvements (excepting kelp farms), plus 1 times the number of unworked improvements, plus 8 times the number of boreholes, plus 6 times the number of echelon mirrors, plus 4 times the number of condensers, plus 1 if the base is a sea base, minus the number of forests. This number is divided by 8, divided again by 2 if the base has a tree farm, and set to 0 if the base has a hybrid forest.
  • Bonus: The base number is 16. Each fungal bloom that occurs in your faction and each Tree Farm, Hybrid Forest, Centauri Preserve, and Temple of Planet produced by your faction after its first fungal bloom increases this number by 1.
  • Intermediate: If Teraforming is non-negative, the lower of Teraforming and Bonus, and otherwise 0.
  • Clean: Bonus - Intermediate
  • Factor: Teraforming - Intermediate + (Minerals - Clean +5*Atrocities)/(1+Mitigators) and rounded down.
  • Perihelion: 2 if active and otherwise 1.
  • Techs: The number of techs known to the faction
  • Life: 1 for a planet with rare life, 2 for normal life, and 3 for abundant life (the maps of "Planet" are 2)
  • Difficulty: 5 for Thinker or Transcend and 3 otherwise
  • Planet: The faction's Planet rating minus 3 or 1 whichever is greater

The eco damage at a base is Factor, times Perihelion, times Techs, times Life, times Difficulty, times Planet, and divided by 300. It is rounded up to 0 if negative.

Governor Settings

There are several governor settings available. If the governor is active and manages population, the governor will assign citizens to work squares or become specialists each turn before their contributions impact the rest of the base functions. If the governor controls production, the governor will select something new to build upon the completion of production if there is nothing in the queue. Otherwise the production will revert to building the same thing or Stockpile Energy if that is imposable. The other settings from the governor menu are self explanatory. When a base is built it inherits the governor settings of the base the colony pod building the base had as its home base.

It is possible to influence the choices the governor makes with the four area buttons on either side of the governor button.

  • Explore: The governor focuses on growing your faction's population by building colony pods and facilities to help this base grow
  • Discover: The governor focuses on advancing your faction's research by building labs enhancing base facilities. It also has a penchant for building probe units and secret projects.
  • Build: The governor focuses of building infrastructure through building base facilities and former units.
  • Conquer: The governor focuses on building military units and sometimes builds a militarily useful base facility.

Combat Effects

There are a number of effects affecting Units involved with units in the base square or attacking the base square.

  • Units with at-least one movement point can always enter a friendly base.
  • Infantry gain a +25% combat advantage when attacking a base.
  • Land units gain a +25% combat advantage when defending a base.
  • Sea units gain a -50% combat advantage when defednding a land base.
  • Base Facilities (Perimeter Defense, Tachyon field, Naval Yard, Aerospace Complex, Children's Creche, Brood Pit) further modify combat (see bellow).

Base Facilities

Base facilities are things at a base that impact how it operates. Each base can only have one and they cannot travel between bases. Satellites are built as base facilities and have factionwide impacts but there is no limit to the number of satellites that can be built. To see a summary of the satellites all factions have built, press the "F6" key from nearly anywhere. Facilities that are free based on faction ability are given to each base built and conquered during the course of the game. These facilities can be scraped or destroyed through the various mechanisms and if so they need to be rebuilt as normal. Bases given facilities on a faction ability do not pay maintenance for those facilities even if they are rebuilt.

Facilities can be destroyed through mindworm attack, base conquest, #Drone Riots, or scrapping them. When a base is conquered, half of its facilities are destroyed. These are randomly chosen. One can scrap a base facility by clicking on the facility and choosing to scrap from the dialog box. A scraped facility no longer provides its benefits (or detriments) but no longer requires maintenance and gives a sum of energy credits when scraped. No more than one base facility may be scraped at a particular base each turn. Facilities given through #Secret Projects cannot be scrapped but those built prior to the secret project providing the facility can be.

Secret Projects

Secret Projects are impressive facilities. Only one of each can ever be built on Planet in each game and they usually have factionwide and significant benefits. They tend to be more expensive than facilities though they are built in the same way. If a secret project is ever destroyed (which can only happen if the base that built it is destroyed), it can no longer be built by any faction in the game. When conquering a base with a secret project, your faction gains immediate benefit of the project.

When a faction is building a secret project, such information is known to all players even if there is no communication possible between them. Switching production from a secret project to another secret project does not lose minerals. A summary of the secret projects built and under construction is available by pressing the "F5" button from almost anywhere. Often building a particular project is a race between multiple factions with the first one to complete it gaining its benefits. The losing factions often switch to other secret projects if they can meaning a losing faction could get the biggest benefit.

Base facilities are sometimes given by secret projects. When this happens, each base has a maintenance free version of the facility that cannot be scraped. Facilities of this type built prior to the base being given it by the secret project (either built before secret project completion or by conquest) still have the original facility. These two facilities only provide one benefit but the original facility still takes up maintenance. This original facility can be scrapped to ease the maintenance burden of your faction and to provide a onetime deposit of energy credits. The original facility can also be left for the event if your faction loses control of the relevant secret project, the base still has the benefit of the facility.
