An authoritative guide to the unique characteristics of the 'advances slots' that intertwine to make the Civ2 technology tree.

Version 1.4.

The Advance Slots

Creating an engaging scenario or mod-pack for Civ2 will in all likelihood involve modifying the advances or technology tree as set out in scenario's rules.txt file. The tree itself can be modified, however a large number of 'slots' (row position in the table) have unique characteristics and care must be taken to ensure that tribes begin with and if appropriate discover technologies appropriate to their circumstance.


Version Changes

Version 1.1 clarifies several differences between FW scenarios and ToT scenarios where known. ToT research in no where near complete so there may be several omissions.

Version 1.2 corrects a long standing misconception about the effects of technology on temples. The effects of advances on the literacy demographic have been revised. ToT advance properties have been removed from this guide and now have their own guide.

Version 1.3 clarifies the properties of Democracy, Explosives, Fundamentalism, Nuclear Fission, Magnetism, Radio and Refrigeration.

Version 1.4 identifies the special unit obsolescence rule associated with Gunpowder and lists the affects of that Flight, Invention, Navigation, and Rail Road have on the gold and science payoffs that caravan deliveries produce.


How to Use this Chart

Slot is the order in which the technologies are listed in the rules.txt. The events.txt file sometimes refers to technologies by slot number.

Code is the abbreviation used to refer to the technology slot in the rules.txt file.

Trigger Effects of Discovery are all hard coded in the software and unchangeable by scenario designers. Effects that are event driven, like winning the game by discovering Transcendence, have been purposely excluded from this chart.

References to other parts of the rules.txt file (improvements, trade items, units) and support files (cities.gif, people.gif) always refer to the appropriate slot in the given section not necessarily the named item. For example if your renamed temples to cathedrals and cathedrals to museums then the discovery of theology would make museums more effective rather than cathedrals.

18 Cst Construction Construction allows settler units to build Fortresses.
19 Cor Corporation
20 Cur Currency

Courthouses make one content citizen happy if the nation is operating under Democracy. However, the Democracy advance is not required for this effect to take place.

22 Eco Economics

24 E2 Electronics After the discovery of Electronics an additional citizen in each city is made content by coliseums.

Electronics works with Automobile to change city pictures to the modern style (6th row in the cities.bmp file).

Electronics works with Automobile to change the look of people to the modern style (4th row in the people.bmp file).

25 Eng Engineering
26 Env Environmentalism Decreases population based pollution.
27 Esp Espionage
28 Exp Explosives Contrary to popular belief, Explosives does NOT inherently allow transformation orders or display the "New Order: Transform" message.

The ability to transform is inherent to unit in the Engineer slot of the RULES.TXT file. When this unit first becomes available the message will be displayed.

29 Feu Feudalism
30 Fli Flight Reduces by one third the amount of gold and science produced by caravan delivery. This affect is cumulative with all other modifiers.
31 Fun Fundamentalism Allows the government type of the same name.

The Fundamentalism advance does NOT inherently allow Fanatics to be build. Only nations operating under the Fundamentalism government can build the Fanatics unit once the advance making the Fanatics available has been discovered.

Upon changing government type from Fundamentalism to any other type all cities producing Fanatics will switch to producing the unit in the Riflemen slot whether or not the nation has the prerequisite advance to build this unit.

32 FP Fusion Power Eliminates the threat of Nuclear Power Plant meltdown.

Adds 25% to spaceship mass/thrust paradigm.

33 Gen Genetic Engineering

Changes the look of people to industrial (3th row in people.bmp).

Changes the types of land-based random Barbarians units produced.

Increases population based pollution.

Upon discovery the Industrialization advance oil appears as a supplied trade commodity in most cities.

38 Inv Invention Reduces by 50% the amount of gold and science produced by caravan delivery. This modifier is NOT cumulative with Navigation or the Turn 200 effect, but is cumulative with the reductions of Railroad and Flight.

Free advances can no longer be gained from goody huts.

Invention works with Philosophy to change the citizen look to the renaissance style (2nd row in the people.bmp file).

39 Iro Iron Working Changes the types of Barbarians produced by Goody Huts.

Changes the types of sea-based random Barbarians units produced.

58 NF Nuclear Fission Upon discovery the Nuclear Fission advance uranium appears as a demanded trade commodity in most cities. Uranium begins appearing as a supplied trade commodity in new founded cities.
59 NP Nuclear Power Nuclear Power increases the movement allowance of ships by one.
60 Phi Philosophy The civilization that first discovers Philosophy gains a free advance.

Invention works with Philosophy to change the look of people to the Renaissance style (2nd row in the people.bmp file).

61 Phy Physics
62 Pla Plastics Increases population based pollution.
63 Plu Ultrastring Theory
64 PT Polytheism Changes the types of Barbarians produced by Goody Huts.
