List of Technologies


Technologies Edit

During the game all nations will race to discover more powerful technologies. A few advances provide immediate benefits, such as making new actions available to your units. Many introduce new units or buildings you can construct. Most are gateways to further technology. Beware that some advances also make things obsolete. While obsolete units merely become impossible to make, obsolete buildings are immediately sold, and obsolete wonders lose their effect.

There are a few ways to gain advances from other civilizations: you will sometimes discover enemy technology when you capture a city; you can steal advances with Diplomats and Spies; and another player might grant technology in the terms of a pact.

By default, each player starts with no technology (this can be changed with a server option). You direct your research toward one advance at a time. Research progress is measured in research points (bulbs), which can be generated both through trade and by scientists. The cost for each technology is fixed and depends on the number of its 'parent techs'. See below the total cost (including parents' cost) for each technology.

Instead of selecting each new advance manually, you can establish a long-term goal that is several technologies away, and your scientists will work through all the prerequisite advances automatically.You can open the research window to view science progress and select new goals. The online help system displays a very helpful technology tree for every item and technology in the game, allowing you to explore the advances they require.

The Space Race Edit

If the server option is enabled, the game may be won peacefully by building a spacecraft and becoming the first civilization to reach Alpha Centauri. One civilization must start the space race by completing the Apollo Program wonder. This allows every civilization with the necessary technology to begin building spacecraft components:

B.space modules Space Module

cost:320 upkeep:0

requires:Superconductors

B.space structural Space Structural

cost:80 upkeep:0

requires:Space Flight

B.space component Space Component

cost:160 upkeep:0

requires:Plastics

The skeleton of your spacecraft consists of structural components, each of which can hold in place either a component or module. Components provide fuel and propulsion systems, and decrease the amount of time your craft will require to reach Alpha Centauri; you can install up to sixteen, though they must be installed in pairs. Modules themselves come in three flavors: a habitation module provides living space for ten thousand colonists; a life support module can keep ten thousand colonists alive; and a solar panel provides the power required by any two other modules.

Use the spaceship window to observe your progress as you build your spacecraft. You may manufacture spacecraft elements anywhere with a factory; they will automatically be assembled in your capital city. As you add components you improve the craft's probability of success and travel time; you may launch as soon as you find these satisfactory. If several civilizations are building spacecraft, they are faced with the decision of whether to launch quickly and start their craft on its way, or continue building in the hopes of launching a faster spacecraft later, or one with a higher probability of success.

Both during construction and after its launch, the spacecraft is considered a building of your capital city, and will be lost if your capital is taken or destroyed.
